[0001] BACKGROUND OF THE INVENTION The present invention relates to making transfer makeup. BACKGROUND It is difficult to obtain a makeup of keratin materials, especially the skin, by transferring an ink deposit printed on a substrate. Indeed, the known inks are such that, once the impression is made, they dry so fast that the transfer to the keratin materials is not achieved. One way of solving this problem is to moisten the transfer surface or the area to be treated with a suitable solvent such as water. However, this method may be unacceptable in that it is not always possible to accurately determine the amount of solvent to be applied, which can lead to "drooling" phenomena making the transfer to keratin materials irregular. and / or unspecific and thus leading to unsatisfactory makeup result. Furthermore, it is desirable to benefit from a makeup system 15 capable of providing a satisfactory makeup transfer in the case of a transfer made immediately after printing, or in the next half-hour, but also in the case of a transfer made a few days or even a few months after printing. In addition, it is also desirable that, once transferred to keratin materials, especially on the skin, the pattern remains relatively stable. In other words, either immediately after transfer, or for example in the hour following the transfer, it is advantageous for the masked area to be touched in particular with the fingers without damaging the pattern produced. However, the makeup coverings conventionally made may not have satisfactory stability in this respect. This lack of stability is not necessarily a problem if a high precision of the makeup pattern is not desired. On the other hand, in the case of precise patterns obtained by printing, it is important that the makeup obtained after transfer is stable. Finally, it can still be advantageous for the user to be able to retouch the transferred pattern in the minutes following the transfer, for example in order to soften the contour and smooth the demarcations with the unmasked area. There is, therefore, a need to benefit from a makeup process allowing makeup to be carried out by single contact transfer, without addition of solvent, that the user seeks to transfer the pattern just after printing or after a period of storage of the device used more or less long.
[0002] There is also an interest in having a transfer makeup device allowing the user, in the minutes following the transfer, to retouch the transferred pattern on keratin materials, if necessary. It is still desirable to have a transfer makeup device for obtaining, in the hour following the transfer, a stable pattern.
[0003] Moreover, the surface of the human body has substantially flat areas such as the back, surfaces which have a generally cylindrical shape (arms, legs) as well as recesses and curved parts, in particular the area of the lips, the nose, underarms, feet ... Now, the transfer by known systems is usually via flat transfer surfaces, for example printable plastic sheets, which hardly adapt to the curved parts of the body. There is therefore a need to benefit from a makeup transfer device adapted to different parts of the body, including those with reliefs. For the latter, it is important that the pattern is applied faithfully while following the relief of the skin.
[0004] The invention aims to meet all or part of these needs. SUMMARY According to a first of its aspects, the present invention relates to a process for making up an area of human keratin materials using a makeup device comprising a deformable substrate having a transfer surface, intended to receive a cosmetic ink. and to come into contact with the keratin materials, the method comprising the steps of: a) depositing, using at least one digital printer on the transfer surface, a layer of at least one cosmetic ink, b. contacting the transfer surface with the area to be makeup by mechanical action, in particular by exerting pressure on a surface of the substrate opposite to the transfer surface, c. move the transfer surface away from the area to be made after transferring the ink. By "human keratin materials" is meant the skin including the scalp, lips, nails, hair, eyelashes and eyebrows; and preferably the skin.
[0005] By digital printer is meant a machine to print in the form of pixels from digital data, different from a machine having a form of printing. The implementation of at least one layer of cosmetic ink obtained by printing with a digital printer advantageously makes it possible to obtain, with great precision, a complex and customizable make-up.
[0006] Thanks to the deformable substrate, the transfer surface easily adapts to the relief of the area to be made up. The flexible and deformable substrate makes it possible to obtain a good transfer even on hollow or projecting areas of the body, in particular the areas of the lips, the nose, the armpits or the feet. The invention advantageously makes it possible to directly print the layer 15 of cosmetic ink on a non-planar transfer surface, corresponding in particular to the outer surface of a roller or a buffer, which facilitates the subsequent transfer to the zones of the body with reliefs. The roller is particularly advantageous for large areas and the buffers are adapted to smaller areas. Ink and printed pattern 20 Preferably, the ink is capable of transferring to keratin materials without the addition of a fluid compound, especially a liquid, third. In other words, the ink can transfer to the keratin materials simply by contacting the area to be made up with said ink without requiring the application of a third liquid to improve the transfer of the ink, as in the case of decals. The ink may be deposited on the printing transfer surface in the form of weft dots and / or weft lines, so as to form a semitone image, for example, monochromatic or polychromatic. The pattern formed by printing on the transfer surface may be of any type. This pattern can reproduce the appearance of relief and / or color heterogeneities of the skin, for example freckles or a skin texture. The pattern formed on the transfer surface can be colored under white light observation in the visible range (400 nm 800 nm). Alternatively, the pattern is colorless in white light in the visible range but may appear as colored after submission to a chemical and / or energetic stimulus, such as UV exposure (365 nm - 400 min) for example when the coloring ink contains a photochromic or fluorescent dyestuff.
[0007] The dyestuff may comprise one or more dyes as described below. The coloring material may be present in the ink in a mass content ranging from 0.01 to 60%, relative to the total mass of the ink, preferably ranging from 0.1 to 40%, or even 0.1 at 30%, preferably ranging from 0.5 to 20%.
[0008] The coloring ink may comprise one or more dyestuffs chosen from water-soluble dyes, fat-soluble dyes, pulverulent dyestuffs such as pigments, in particular nacres, and flakes, or even coloring polymers. By "pigments" it is necessary to include particles of any shape, white or colored, mineral or organic, insoluble in the cosmetic medium, intended to color the cosmetic ink. By "nacres", it is necessary to understand particles of any iridescent form, in particular produced by certain shellfish in their shell or else synthesized. The pigments can be white, black or colored, mineral and / or organic. Examples of inorganic pigments are titanium dioxide, optionally surface-treated, zirconium or cerium oxides, as well as oxides of zinc, iron (black, yellow or red) or chromium, violet manganese, ultramarine blue, chromium hydrate and ferric blue, metal powders such as aluminum powder, copper powder. Among the organic pigments, mention may be made of carbon black, D & C type pigments, and lacquers based on cochineal carmine, barium, strontium, calcium, aluminum. The pearlescent pigments may be chosen from white pearlescent pigments such as mica coated with titanium, or bismuth oxychloride, colored pearlescent pigments such as titanium mica coated with iron oxides, titanium mica coated with, for example, ferric blue or chromium oxide, titanium mica coated with an organic pigment and pearlescent pigments based on bismuth oxychlortre.
[0009] Among the water-soluble dyes, mention may be made of the disodium salt of a culvert, the disodium salt of alizarin green, quinoline yellow, the trisodium salt of amaranth, the disodium salt of tartrazine, the monosodium salt of rhodamine and the disodium salt. fuchsin, xanthophyll, methylene blue.
[0010] Among the liposoluble dyes, mention may be made of Sudan Red III (CTFA: D & C Red 17), lutein, quinizarin green (CTFA: D & C green 6), SS alizurol purple (CTFA: D & C violet No. 2) , Sudan brown, DC Yellow 11, orange DC 5, quinoline yellow, curcumin, carotenoid derivatives such as lycopene, betacarotene, bixin or capsanthine, and mixtures thereof. The coloring polymers are generally copolymers based on at least two different monomers, at least one of which is a monomeric organic dye. Such polymeric dyes are known to those skilled in the art. For example, it is possible to refer to the documents: US Pat. No. 5,032,670; U.S. 4,999,418; US 5,106,942; U.S. 5,030,708; US 5,102,980; US 5,043,376; US 5,104,913; US-5,281,659, US-5,194,463; U.S. 4,804,719; WO92 / 07913, or alternatively EP1048282. The coloring ink may comprise one or more dyestuffs, in particular pigments, photochromes, ie dyestuffs which have the property of changing color when they are irradiated by a light source of a certain frequency, then of resume their initial color, or a close color, when stopping the irradiation. Amongst the photochromic dyestuffs, there may be mentioned: - photochromic, inorganic and complex compounds and more particularly doped aluminosilicates and oxides and hydrates of metal oxides, such as those described in WO-A-02/36083, - compounds photochromes of naphthopyrans, in particular 3H-naphtho- [2,1-13] -pyrans or 2H-naphtho- [1,2-M-pyranes, for example 3,3-di (4-methoxyphenyl) -6- morpholino-3H-naphtho [2,1-1)] pyran, 3-phenyl-3- (4-morpholinophenyl) -6-morpholino-3H-naphtho [2,1-b] pyran e, 3-phenyl- 3- (4-piperidinophenyl) -6-morpholino-3H-naphtho [2,1-b] pyran, 3-phenyl-3- (4-piperidinophenyl) -6-carboxymethyl-N-dimethyl-3H-naphthoate [2,1-Bipyran, 2-phenyl-2- (4-piperidinophenyl) -5-carboxymethyl-9-N-dimethyl-2H-naphtho [1,2-b] pyran. Such compounds are described in application EP-A-1410785, diarylethene or fulgide compounds such as those described in application EP-A-938887. The coloring ink may further comprise one or more fillers, especially in a content ranging from 0.01% to 50% by weight, relative to the total weight of the coloring ink, preferably ranging from 0.01% to 30% by weight. By "fillers" it is necessary to include particles of any shape, colorless or white, mineral or synthetic, insoluble in the medium of the coloring ink regardless of the temperature at which this ink is manufactured. These fillers serve in particular to modify the rheology or the texture of the coloring ink. The fillers can be mineral or organic of any form, platelet, spherical or oblong, irrespective of the crystallographic form (for example sheet, cubic, hexagonal, orthorhombic, etc.). Mention may be made of talc, mica, silica, kaolin, polyamide (Nylon®) (Orgasol® from Atochem), poly-13-alanine and polyethylene powders, tetrafluoroethylene polymer powders (Teflon). ®), lauroyl-lysine, starch, boron nitride, polymeric hollow microspheres such as those of polyvinylidene chloride / acrylonitrile such as Expancel © (Nobel Industrie), acrylic acid copolymers (Polytrap® from Dow Corning) and silicone resin microbeads (Toshiba Tospearls®, for example), elastomeric polyorganosiloxane particles, precipitated calcium carbonate, magnesium carbonate and hydrocarbon, hydroxyapatite; hollow silica microspheres (Silica Beads® from Maprecos), glass or ceramic microcapsules, metal soaps derived from organic carboxylic acids containing from 8 to 22 carbon atoms, preferably from 12 to 18 carbon atoms, for example, zinc, magnesium or lithium stearate, zinc laurate, magnesium myristate. The coloring ink may comprise in addition an additional polymer such as a film-forming polymer. The term "film-forming polymer" means a polymer capable of forming, by itself or in the presence of a film-forming auxiliary agent, a continuous and adherent film on a support, in particular on keratin materials. Among the film-forming polymers that may be used in the coloring ink, mention may be made of synthetic polymers, of radical type or of polycondensate type, polymers of natural origin and their mixtures, in particular acrylic polymers, polyurethanes, polyesters, polyamides, polyureas, cellulosic polymers such as nitrocellulose. Of course, those skilled in the art will take care to choose this or these optional additional compounds, and / or their quantity, in such a way that the advantageous properties of the coloring ink are not, or not substantially, impaired by the addition envisaged. . The coloring ink may be in fluid or powder form when carried by the transfer surface and before application to the keratin materials. When it is fluid, the coloring ink has for example a viscosity ranging from 10 1mPa.s to 500 mPa.s, and preferably from 1mPa.s to 300 mPa.s at 25 ° C. The viscosity of an ink of the invention may be measured according to any method known to those skilled in the art, and in particular according to the following conventional method. At 25 ° C using a Rhéomat 180, equipped with a mobile rotating at 200 rpm, the skilled person can choose the mobile device for measuring the viscosity, among the mobile, M1 or M2 or 15 M3 or M4 on the basis of his general knowledge, so that the measurement can be carried out. The coloring ink may be in the form of an emulsion. When the ink is in the form of a cosmetic toner, this toner may further comprise a coloring agent, an electric charge control compound, a particular additional filler, a lubricant, a wax and / or a binder. Preferably, the toner particles have an average size of between 1 and 16 μm. The toner comprises, for example, pigments having a particle size of between 1 and 10 μm. In a particular embodiment, the ink is brought to a temperature of between 30 ° C. and 60 ° C. before it is applied to the substrate or to the keratin materials, in order to thin it; the ink can be formulated to produce a solid material after printing and cooling to a temperature of 20 ° C. The printing can implement several different inks, including inks of different colors. The printing may employ at least three, including at least four, five, six, seven, eight, nine, ten, eleven or twelve coloring inks of different colors.
[0011] Printing can only use coloring inks that produce primary colors. Alternatively, the printing uses both coloring inks producing primary colors and at least one coloring ink producing a non-primary color.
[0012] The printing of the coloring ink can be a tri-color or four-color printing. The pattern obtained by printing may have several different color areas. Alternatively, the pattern obtained by printing is a solid color. The coloring ink can be deposited in several printing passes. In other words, one can first print a first fraction of the coloring ink on the transfer surface and then a second fraction of the coloring ink on all or part of the first fraction. Printing can also follow geometric rectification rules. Since the transfer surface is deformable, during application the pattern may be geometrically deformed (eg extension in one of two dimensions). As a result, the pattern is printed with a geometric deformation (in this case reduction according to the deformable dimension (s)) so that after application, the pattern is at the desired scale. Geometric rules can be applied: either universal or specific to the pattern to be printed on the transfer surface so that the pattern has the desired shape after transfer to the zone of the keratin materials to be treated. The use of such rectification rules is particularly advantageous with a substrate having a transfer surface having reliefs, in particular to marry an impression, as seen below. In particular, it is possible to use specific geometrical rules adapted to the zone to be treated and / or to the desired pattern. In an exemplary embodiment, the substrate is coated with a dry colored coating, the coating comprising a pigment and / or a colorant, the colorant ink being printed on the coating and a third compound assisting the transfer being then optionally applied, for example an oil and / or a pressure-sensitive adhesive. Substrate The substrate is preferably non-absorbent. The substrate is advantageously non-porous, at least on the transfer surface intended to receive the cosmetic ink.
[0013] The substrate comprises or consists of a deformable material, in particular thermoplastic and / or elastomeric material. Preferably, the substrate is elastically deformable. The substrate may be monolayer or multilayer.
[0014] The substrate is advantageously compressible. The substrate, in particular to increase the compressibility thereof, may comprise one or more porous layer (s), especially in its core. The substrate may comprise a material incorporating cells or microspheres. Preferably, the substrate is made in such a way that, during the transfer of the ink onto the keratin materials, the substrate is easily deformable by simple pressure exerted on the face opposite to the transfer surface, which improves the contact of the the latter with the keratin materials. The transfer surface defines for example at least one cylinder or sphere portion. The transfer surface may be defined by all or part of: the outer surface of an applicator roller, a surface of an applicator pad, a sheet element, a patch, the surface of a porous foam, in particular a sponge or a wipe. The transfer surface may be defined by a mixture of elastomers. The transfer surface is defined for example by at least one elastomer chosen from the following nonlimiting list: butadiene-styrene, butadiene-nitrile, isobutylene-isoprene copolymerized, chloroethylene-polysulfide copolymerized, polysulfides, EPDM (ethylene-propylene-diene monomer) or polyethylene-propylene diamine or polyurethanes. The substrate comprises, for example, an elastomer, in particular a silicone elastomer, for example VMQ or MQ, FVMQ, PVMQ; (described in the book of rbsimpson 2002, rubber basics p96 - ISBN 1-85957-307-X). As an example of elastomer can be used that sold under the name Patsile GEL 10 by the company Polytek. The material defining the transfer surface may comprise at least one additional filler, a plasticizer (eg glycol ethers, phthalates or silicone oils), a coloring agent (pigment or dye), a protective agent to increase the resistance to light (UV filters), a vulcanizing agent and / or a vulcanization accelerator (sulfur, zinc oxide).
[0015] The additional compound (s) present in the material defining the transfer surface may serve in particular to improve the resistance to oils and solvents, present in the ink or used for cleaning the substrate. The transfer surface can be brought into its final form by molding (especially for crosslinkable materials), machining, laser machining, sintering, sanding, calendering of a substrate, etc. The transfer surface is preferably smooth and has a roughness less than or equal to 1 mm, especially between 1 and 100 jun. The roughness is measured using a rugosimeter, whose tip has a radius of curvature of 10 mm and whose force, applied to the material to be characterized, is 6 mN. The substrate may have a hardness of between 1 and 30 Shore A, preferably between 5 and 20 Shore A, and more preferably between 8 and 15 Shore A, for example equal to 10 Shore A, measured according to DIN 53 505 standard. , ISO / R868 The thickness of the substrate may be adapted to the keratin materials to be made up. The thickness of the substrate corresponds to its dimension measured perpendicularly to the transfer surface. Depending on the location on the transfer surface, the thickness of the substrate may be constant or not. For example, when the coloring ink is intended to be applied to the cheeks and / or the nails, the substrate may have a thickness of between 1 mm and 3 mm, or even greater than 3 mm. In an exemplary embodiment, the coloring ink is intended to be applied to the periocular zone and / or to the lips and the substrate has a thickness of between 3 mm and 1 cm, or even greater than 1 cm. In another embodiment, the coloring ink is intended to be applied on the nose and / or in the area of the ears and the substrate has a greater thickness, between 1 cm and 3 cm, or even greater than 3 cm. In a variant, the substrate is made in a "pre-molded" form in order to facilitate its adaptation to the relief of the keratin materials, for example the negative of the lips or of the ocular orbit.
[0016] The substrate may be in the form of a printing blanket, in particular as used in the field of printing, comprising, in a known manner, a carcass intended to ensure mechanical performance and a decalcographic layer, also called a top, defining the surface of the printing surface. transfer and charged to bring the transfer performance. In an exemplary embodiment, the substrate is at least partly covered with a coating, which can be colored and itself able to transfer to human keratin materials. The coating may be colored with a color that is difficult to print, for example white or black, or a color close to the complexion of the skin to be made up, such as a flesh color. Alternatively, the coating is not colored in itself The coating may comprise transfer enhancing adjuvants, such as oily bodies, and / or improving the hold and / or intended to protect the skin, such as sunscreens. This or these coatings may also be applied to the substrate after printing thereof by the coloring ink. In an exemplary embodiment, the substrate comprises at least one translucent or transparent zone. The translucent or transparent zone allows a user to see through the substrate and thus to visualize more easily the surface to be made up before transfer of the coloring ink. The presence of a translucent or transparent zone thus advantageously contributes to facilitating the obtaining of a precise makeup. The translucent or transparent area may be superimposed in whole or in part with the coloring ink layer, and in particular overflow thereof. The entire dye ink layer may be superimposed on the translucent or transparent area. Alternatively, only a portion of the coloring ink layer is superimposed on the transparent area. The substrate may be made entirely of a transparent or translucent material. In this case, the translucent or transparent zone extends over the entire surface of the substrate. In an exemplary embodiment, the coloring ink is printed in a predefined pattern, the method comprising a step of choosing and / or producing the pattern by a user and transmission, by an apparatus connected to at least one printer carrying out the printing. impression, of information associated with this motif. The device can be a computer, an advanced mobile phone, also called "smartphone", or a touch pad. The apparatus may be physically connected and / or through a data exchange network to said printer. During the printing step a), the system can be at least partially assembled to the printer. At least during step b) of bringing the transfer surface into contact with the zone to be made up, the substrate may be supported on a support element of the system. During printing, the substrate is for example supported by a removable substrate holder. Support The substrate may be fixed for printing and / or transfer to the keratin materials on a support independently, in particular by friction, the support being able to assist in the handling of the substrate. The substrate can conform to the shape of the support. The substrate can be glued directly to the support, for example being self-adhesive. A self-adhesive substrate is particularly easy to handle, especially when its dimensions are relatively small. The substrate may be tubular. 11 may be symmetrical or not about a longitudinal axis. The support can be cylindrical. The support can be full or hollow. In an exemplary embodiment, the substrate is plated on the support, in particular by virtue of its elastic properties. The substrate may have been plated on the support at the time of attachment thereto. Alternatively, the substrate is plated on the support only during use, for example under the action of a depression. The support may have the shape of a sphere or cylinder part, in particular of right cylinder. In a variant, the support has a flat surface on which the substrate is pressed. The support may have a convex outer surface.
[0017] The support may have a concave outer surface, for example a developable surface facilitating the plating of the substrate. In one variant, the support has an advantageous hourglass outer shape for pressing a tubular substrate of variable thickness, which is thinner at the ends and whose greater thickness in the center facilitates application to raised body surfaces. the shape of an applicator roll or a tampon. A roller shape facilitates a regular distribution of pressure and a homogeneous transfer of the pattern. It makes it possible to easily cover flat or rounded areas such as the back, the belly, the limbs or even the cheeks. The substrate may deform upon transfer due to the force that the roll exerts on the face of the substrate opposite to the transfer surface. The dimensions of the roller are adapted to the area to be made up and / or the size of the desired patterns. The outer diameter of the roll is for example between 0.5 and 20 cm or even between 1 and 10 cm. The width of the roller, measured parallel to its axis of rotation, is for example between 0.2 and 40 cm, or between 10 and 200 mm. These dimensions are particularly suitable for making up the cheeks, the arm, the eyelids, the back, the ankle and the scalp. Roll and buffer According to another aspect, the present invention relates to a roll intended to be used on a printer according to the invention as described above, the roll carrying a deformable substrate defining the transfer surface, intended to receive a particular cosmetic ink to transfer by contact in particular with the keratin materials, the transfer surface forming at least partly the outer surface of the roll. The substrate may be fixed on the roll by any appropriate means known to those skilled in the art, in particular by friction or gluing.
[0018] In a variant, the roller comprises means for fixing the substrate, in particular at least one clamp or one fixing jaw. The roll may further comprise a removable substrate holder. The substrate can marry the reliefs of the roll, for example being molded on the roll. In a variant, there is a space between the substrate and the roll, especially at the moment of printing. During the transfer the substrate is pressed against the roll and the transfer surface is deformed to coincide with the relief of the area to be made up.
[0019] The roll may be in the form of a straight cylinder. In a variant, the roller has the shape of an irregular cylinder, for example the shape of an hourglass. In a variant, the roll is "pre-molded", that is to say that it has a non-planar initial shape corresponding to the general shape of the zone to be made up, for example the lip-negative, of an ocular orbit , ankle or forearm. The roll may comprise a holding system, in particular a handle to be housed removably in the printer at the time of printing. The holding system thus serves to hold the roll at least during its implementation for printing and in a preferred variant also during the transfer.
[0020] The handle comprises for example two symmetrical jaws configured to be assembled at both ends of a roller. The handle may comprise a device for indexing and / or locking in rotation of the roller. Preferably the holding system is removable. The holding system is in particular arranged to be used with several rollers. The roller can be heated. The roller can be full. In a variant, the roll is hollow and in particular arranged to house a heating element.
[0021] According to yet another of its aspects, the present invention relates to a buffer door for use with a printer according to the invention. The buffer holder is arranged to carry at least one buffer carrying a substrate with a transfer surface, in particular intended to come into contact with the keratin materials.
[0022] The buffer can carry a single tampon. The buffer holder can be arranged to simultaneously carry several buffers, the buffer holder can carry in particular between 1 and 5 buffers, for example 3 buffers. A buffer may thus correspond to a portion of a cylinder, for example defined by an angle of between 100 and 210 °. The part of the cylinder is in particular between 1/10 and 4/5 of cylinder, in particular between 1/5 and 3. / 4 cylinder, or even correspond to a quarter cylinder or a half cylinder.
[0023] In a variant, the substrate fixed on the pad is pre-molded, for example for make-up by transfer onto an eyelid. The buffer holder may include a holding system to be housed with the pad (s) removably in the printer at the time of printing.
[0024] The holding system of the buffer holder is preferably removable. It can be identical to the maintenance system described above. In particular it can be used interchangeably with a roller or with a buffer door according to the invention. In a variant, the transfer is carried out by positioning the substrate without bearing on the keratin materials, a direct manual pressure on the external face, opposite to the transfer surface, thus facilitating makeup by transfer of the cosmetic ink. In a variant, to facilitate the adaptation of the transfer surface to the relief of the zone to be made up, after the printing of step a) and before step b) of contacting the transfer surface with the zone to be made up, the substrate is pressed against an impression forming part of the support by the action of deformation means. The shape of the impression may correspond to the area of the keratin materials to be made up. The substrate is then deformable, between: a first configuration in which the substrate is fixed on the support and defines with the cavity a space, and a second transfer configuration, in which said substrate is pressed onto the substrate; impression under the action of deformation means. The substrate thus passes from the first configuration, in which it has a smooth, particularly planar or cylindrical surface of revolution, which is easily printed, in the second configuration, in which the substrate can be shaped so as to take the form of keratinic make-up. The first configuration may correspond to a print configuration or not. The substrate is preferably reversibly deformable between the first and the second configuration, the reversibility being provided preferably by the inherent elasticity of the substrate. In the second configuration, the relief of the support may correspond to the relief of the area to be made up, thus forming a counter-mold of said zone. The method may comprise a preliminary step of producing the imprint. The impression may in particular be made by direct molding of the area to be made up or from such a molding, indirectly, for example using an intermediate mold. The molding is for example made of plaster, particularly with plaster strips, with alginate or silicone. In a variant, the impression is made by a 3D printer, for example, by processing relief data of the area to be made up, for example stereoscopic images thereof; these images may include a projection of fringes. This embodiment is particularly advantageous for areas for which it is difficult to take a direct impression, especially the area of the eye. The impression can be fixed and correspond for example to a particular body area of a given user. In another exemplary embodiment, the imprint is variable, which makes it possible to change at will the shape that the substrate will take for the transfer.
[0025] The support may comprise a system for varying the shape of the impression, making it possible to modify its shape, in particular by means of at least one actuator, in particular in the context of a computer-assisted system. The shape variation system of the imprint may include any type of actuator. This system comprises for example an assembly of several movable rods, in particular between 10 and 4096 rods, or even between 64 and 4096 rods, in particular between 64 and can be controlled in displacement independently of each other. In the first configuration, the transfer surface is for example flat or curved. In a preferred variant, the transfer surface is "pre-molded", that is to say that it has a non-planar initial shape corresponding to the general shape of the zone to be made up, for example the negative of lips, d an ocular orbit, ankle or forearm. The space between the substrate and the cavity that extends in particular between the face of the substrate opposite the transfer surface and the cavity, can be filled with a fluid, for example air, compressed or not, or of a liquid. A fluid is for example injected into the space between the impression and the substrate to create an overpressure during printing. The substrate appears inflated. In such an example, the substrate is preferably pre-molded.
[0026] In the second configuration, the substrate is pressed onto the impression due to a mechanical action of the deformation means. Preferably, the mechanical action is performed without contact with the transfer surface. The deformation means may exert a force on the face of the substrate 5 opposite to the transfer surface. The deformation means may be pneumatic or hydraulic. The deformation means can still be arranged to create a suction vacuum. The deformation means comprise, for example, suction means for emptying the aforementioned space. The method may also include a step of finishing a pattern formed by at least one ink carried by the transfer surface. This finishing step of the pattern can be performed for example with the fingers or a special tool. For example, pressure is applied to certain areas where certain areas are heated. Once the ink has been transferred to the keratinous material, the transfer surface is moved away from the area of said material and the substrate is preferably removed from the support, if any. The deformation means may be reversible and facilitate the separation of the substrate from the support, in particular to facilitate cleaning after transfer to the keratin materials. The method may further comprise a step of finishing the makeup obtained on the keratinous materials, for example so as to blur the boundaries between a first zone made up with a first ink and a second zone not made up or made up with a second ink. . The makeup finishing step is performed for example by exerting friction on all or part of the transferred pattern. According to another of its aspects, the present invention relates to a cosmetic device for the makeup of human keratin materials by a method according to the invention as described above, the device comprising: a deformable substrate defining a surface of transfer, intended to receive a cosmetic ink to be transferred by contact with the keratin materials, - a support located at least partially opposite the transfer surface, on which the substrate is fixed and against which the substrate bears at least during the transfer of the cosmetic ink to the keratin materials, - support holding system on a digital printer.
[0027] The device may comprise a substrate and / or a support as described above. With the device holding system, the support can be assembled completely or not with the printer at the time of printing on the transfer surface. The holding system may or may not be integral with the support during transfer to the keratin materials. The carrier may be at least partially assembled to the printer when ink is removed by printing. The holding system can be configured to associate all or part of the carrier with the printer by attaching it to the printer or feeding it into the printer. The holding system can be configured to assemble at least one frame of the support to the printer, the substrate being fixed to the frame, in particular stretched. The frame may be of elongated shape, for example rectangular. The device may comprise a removable part, called a "substrate holder" in the context of the invention, present at least at the time of the removal of the ink on the transfer surface, to support the substrate and thus facilitate the accurate printing of the pattern. Preferably, the support with the impression is secured to the substrate at the time of printing and the holding system is configured to assemble the complete device to the printer. The substrate holder may be used for printing and removed manually or automatically after printing. The substrate holder is for example a roller whose axis protrudes on each side to be able to slide the roller along two rails of the frame and approach the printing area. In exemplary embodiments, only a portion of the device is assembled to the printer. For example, only the substrate, the frame, and the optional substrate holder are attached to the printer during printing, then separated from the printer and attached to an imprint of the medium. The transfer surface can follow the shape of the substrate holder, in particular be flat or curved at the time of printing and then be deformed with the substrate 5 under the action of deformation means. During the printing step, the substrate is for example supported by a substrate holder in the form of a plate, which is removed before the makeup transfer step on the keratin materials. Alternatively, the support directly supports the substrate with sufficient dimensional stability when depositing the ink without the need for a substrate holder. In a variant, in particular when a fluid is injected into the space between the cavity and the substrate, as explained below, in order to create an overpressure sufficient to support the substrate at the time of printing, a "carrier" substrate "is not necessary. Advantageously, the substrate is reusable. Thus, after use, the transfer surface can be cleaned. The cleaning of the transfer surface can take place while the substrate is removed or not from the support. Preferably, the substrate is removed from the substrate and the substrate holder for cleaning in order to take advantage of the flexibility of the substrate, and then the substrate can re-enter the device that is ready for re-printing. The device may comprise a layer of at least one cosmetic ink deposited on the transfer surface. The coloring ink present on the device just before the transfer may not be completely dry. The application of a not completely dry coloring ink on the keratin materials facilitates the transfer of the ink. The device may comprise a heating element, in particular for thinning the dye ink layer and facilitating its transfer to the keratin materials. In an exemplary embodiment, the device, in particular the substrate, comprises an indication printed with the same ink or not as that intended to transfer. The indication specifies, for example, the nature of the keratin materials intended to be made up by the coloring ink or illustrated on the scale, enlarged, reduced or not, and "on the spot" the pattern deposited "upside down" on the substrate. The device may also comprise a gripping member to allow holding and facilitate the contact of the transfer surface with the keratin materials during the transfer of the ink. Sets According to another of its aspects, the present invention relates to a cosmetic assembly comprising, within the same packaging, a plurality of devices according to the invention as defined above.
[0028] The devices of the set may or may not include a coloring ink, deposited on their transfer surface. The devices may differ in the form of the support, especially the footprint. The devices may differ in the form and / or composition of the substrate, in particular the transfer surface intended to come into engagement with the keratin materials. The devices may differ in the chemical nature of the coloring ink they bear and / or in the pattern formed by it. According to one of its aspects, the present invention relates to a cosmetic assembly comprising, within the same packaging, one or more devices as defined above, and at least one of a coloring ink cartridge and deforming means for pressing the substrate of a device onto an impression. The assembly may comprise a plurality of ink cartridges and deformation means of the substrate. The assembly may also include a suitable printer. Printer According to yet another of its aspects, the present invention relates to a digital printer configured to deposit by printing a cosmetic ink on a transfer surface of a device according to the invention. By digital printer is meant a machine for printing in the form of pixels from digital data, different from a machine having a printing form. The printer may be an inkjet ("Inkjet") printer, for example thermal or piezoelectric, a sublimation printer or a laser printer. In one example, the printer is a laser printer arranged to allow electrophotography or magnetophotogaphy formation of an ink layer having a pattern on a transfer surface from at least one cosmetic toner and to deliver the toner. present on the transfer surface in a sufficiently free state to allow its removal or transfer by contact with human keratin materials. By "cosmetic toner" is meant a powdery cosmetic composition compatible with image formation by an electrophotogaphic or magnetophotographic process as practiced within laser printers. Preferably, it is a toner that is suitable for electrophotographic processing. The toner is cosmetic in that it is compatible with application to human keratin materials. Depending on the surface to be made up, the formulation of the toner may be different. For example, for an application on hair or nails, it is possible to use certain compounds that could not be used for an application on the lips, for example. The printer may be a Gatocopy A426 food-grade inkjet printer for printing on non-planar objects. The use of such a printer is particularly suitable for certain exemplary embodiments as described above and makes it possible in particular to print on a "pre-molded" substrate OR directly on a device with an imprint, the nozzles of the printer. for example, at a distance from the transfer surface of between 0.1 mm and 5 mm, preferably between 0.1 mm and 2 mm. The printer may comprise a receptacle configured to cooperate with the holding system of a device according to the invention. The printer may advantageously comprise means for rotating a roller and / or a buffer support, hereinafter referred to as "roller drive means 30".
[0029] The roller driving means may comprise gears configured to synchronize the rotation of the roller with the scanning of the printing nozzles. The printer may comprise feet, especially adjustable, to avoid friction when the driving means of the roller rotate the roller or the buffer (s) carried by the buffer holder. The printer may comprise a receptacle for housing, at least at the time of printing, a roller or a buffer holder carrying at least one buffer. The receptacle may be used to removably accommodate the roll or the stamp medium. The receptacle may comprise at least one slide for setting up and removing the roller or the buffer holder by guiding them. With the slides, once the roller or the buffer holder inserted into the slides, the transfer surface arrives near the print nozzles. The printer may comprise a roller or a buffer support, which are removable for example to facilitate the cleaning of the transfer surface and allow to choose to use a buffer or a roller from an available range. In a variant, the printer has a window for access to the transfer surface and the transfer of the ink is possible while the substrate is present in the printer. The printing width is for example between 0.2 and 40 cm, preferably between 5 and 200 mm, especially between 10 and 120 mm, more preferably between 10 and 80 mm, or even between 10 and 60 min. Preferably, the printer comprises at least one cosmetic ink cartridge. The printer may have several cartridges including several cartridges of different colors. The invention will be better understood on reading the description which follows, examples of non-limiting implementation thereof, and on examining the appended drawing, in which: FIGS. 1A-1C represent, in perspective and in elevation, an example of a makeup device according to the invention, - Figures 2A and 2B show the device of Figures 1A-1C and a suitable printer, - Figure 3 illustrates a makeup process according to the The invention, using the device of FIGS. 1A-1C, - FIG. 4 is an exploded view of a variant of a make-up device according to the invention; FIGS. 5A-5F illustrate different stages of a make-up process according to FIG. FIGS. 6 and 7 show examples of cosmetic assemblies according to the invention; FIG. 8 is a block diagram illustrating various steps of a make-up process according to the invention; FIGS. 9A to 9C represent in elevation other example the devices according to the invention before fixing the substrate, - Figures 10A to 10D show in elevation of the device variants according to the invention, and - Figure 11 is a partial sectional view of a device variant according to the In the invention, FIG. 1A shows a make-up device 1 according to the invention, comprising a substrate 2 defining a transfer surface 3. The substrate 2 is made of a flexible, compressible and deformable material. The substrate 2 is constituted in the example illustrated by a printing blanket made of elastomeric material, plated on a support 20 in the form of a hollow roller 200 on which it is fixed by simple friction. The transfer surface 3 is smooth and has a roughness of less than or equal to 50 μm measured using a roughness meter as described above. The transfer surface 3 constitutes the outer surface intended to receive a layer of cosmetic dye 4, to make a make-up transfer. In order to deposit the coloring ink layer 4 on the transfer surface 3, a digital printer 500 illustrated in FIGS. 2A and 2B is used which deposits the ink dots in correspondence with the pixels of an image to be reproduced.
[0030] As illustrated in Figure 1B, a removable handle 80 may be secured to the support 20 to act as a gripping member to hold the device during the transfer of makeup. It is advantageous for the gripping member 80 to be removable; thus it can be removed as illustrated in Figure lA to more easily allow to press the substrate 2 on the support 20 and to clean it between two uses. The handle 80 comprises in the example in question two plastic jaws made of machining POM, intended to be assembled at both ends of the support 20 in the form of a roller. In the example under consideration, the gripping member constitutes the holding system 250 used during printing. Alternatively, the holding system is different. As illustrated in FIGS. 2A and 2B, during printing, the device 1 is assembled to the printer 500 thanks to the cooperation of a holding system 250 of the device 1 with a receptacle 520 of the printer 500, allowing by For example, snapping the applicator roll onto the printer 500. In these figures, the outer case of the printer 500 has been removed to illustrate the integration of a device according to the invention. While Fig. 2A shows the receptacle 520 in the absence of a device, Fig. 2B shows the printer 500 housing the device 1. The roll is not visible in the figure. In a variant, a handle has been assembled to the handle 80 bearing, for example, three buffers. The receptacle 520 comprises for example two slides 525 for accommodating and guiding the handle 80 assembled to the roller or the buffer door and thus facilitate their installation and removal from the receptacle 520. The transfer surface 3 is thus placed near the nozzles In order to provide good accuracy of the pattern formed by the ink layer 4, the distance between the nozzles and the transfer surface is, for example, between 0.5 mm and 1.5 mm. The printer 500 also includes drive means 535 of the roller with configured gears for scrolling the substrate 2 at the time of printing and synchronize the rotation of the roller 200 on the scanning of the printing nozzles. The driving means of the roller 525 are for example at least partly located in a flange to the left of the receptacle 520.
[0031] The printer also comprises four feet 530, for example adjustable, to avoid when printing friction of the roller or buffer (s) carried by the buffer holder and rotated. FIG. 1C shows the device 1 once removed from the printer 500, the transfer surface 3 carrying a layer of cosmetic ink 4. A pattern 40 inverted representing the image to be reproduced is printed directly on the transfer surface 3 using the printer 500. The ink layer 4 can form any type of pattern. The pattern may consist of several inks. The substrate 2 may carry information 7, for example formed by printing, to provide advice on a recommended positioning for makeup, or information on the nature of the keratin materials to be masked by the ink 4, or other . The device 1 may further comprise a heating element, not shown and located for example inside the support 20. FIG. 3 is a diagram of an example of a make-up method according to the invention. The roll 200 of FIGS. 1A-C, once the printing has been done, is for example exited from the receptacle 520. The makeup by transfer can be carried out just after printing or in the next half-hour, but also for a few days or even a few months after printing. By holding the handle 80, the user approaches the roll 200 of the keratin materials so as to bring into contact, as illustrated, the coloring ink layer 4 with the zone P to be made up, the forearm in the example illustrated, which is preferably dry, then the user rolls the transfer surface 3 by applying a pressure to perform the transfer of the dye ink 4 on the area to be painted P. As illustrated by the arrow f, the pressure s is applied via the support 20 to the face of the substrate opposite to the transfer surface 3. Upon contact with the keratin materials, the roll 200 advances in the direction of the arrow t and the substrate 2 is preferably not moved laterally so as not to affect the appearance of the transferred pattern.
[0032] The pattern transferred to the keratinous material corresponds in positive to the pattern 40 formed in inverted by the dye ink layer 4 when it is present on the substrate 2 (ie when it is not yet transferred to the keratin materials to make up) and faithfully reproduces the original image.
[0033] FIG. 4 illustrates a device 1 according to a second embodiment of the device 1 comprises an elastically deformable and compressible substrate 2 having a smooth transfer surface 3, configured to receive a layer of cosmetic ink 4 and can be fixed on a support 20 by a frame 6.
[0034] The device 1 also comprises a removable substrate holder 12 which allows the stability and maintenance of the substrate at least during the removal of the cosmetic ink layer 4. The substrate holder may be of rigid or semi-rigid material. The substrate holder may comprise a flexible plate. The support 20 may be configured to form an impression 60 of the zone of the keratinous materials to be made up. The support 20 can be transformable and adaptable to the relief of a zone P of the human keratin materials to be made up to form a suitable impression. In the illustrated example, the support 20 comprises a plurality of rods 601 movable along the double arrow S, for example between 10 and 500 rods, better still between 100 and 500 rods, each disposed in a hole 605 of a guide 610 which can be soft or hard. There are small stems in each of the holes. The length of the rods is greater than the thickness of the guide. The system is embellished with a means preventing the rods from coming out of the hole without preventing the rods from moving. For example, on the rear face, there may be another membrane blocking the output of the rods or each rod is retained by an elastic zone, or each rod has one or two lugs limiting the displacement beyond a certain race. The movable rods can be moved individually or in groups by mechanical pressure, especially when taking an impression directly on the area to be made up. In a variant, the movable rods can be moved by hydraulic pressure, or electromagnetic or electrostatic force, especially when direct molding is not possible or desired. The movable rods are for example displaced by an actuator system. The support may comprise a system for allowing the stems to be blocked, at least temporarily, after making the impression, so that they do not move before the transfer of the ink. This system can implement a mechanical force, an electromagnetic or electrostatic force. This system can be a brake system that is deactivated to move the rods and active to block them. Preferably, the presence of friction between the stems means that the force acting on the ends of the stems during substrate plating or during transfer is not sufficient to move the stems. The rods thus come into contact with the substrate during the plating and then give it protruding reliefs and depressions by pressure. In a variant not shown, the support further comprises a flexible membrane above the group of rods so that the rods do not come into contact with the keratin materials during the impression taking. In a variant not shown, the support comprises an outer surface formed of a movable membrane and a system of actuators, in particular cylinders, configured to deform the movable surface and / or maintain it in a position corresponding to the reliefs of keratin materials in particular after direct capture of the imprint or image processing. Each cylinder can be moved by means of an electromagnet or by a pneumatic or hydraulic force. In another variant, as illustrated in FIGS. 5A-E, the support comprises a fixed-form impression 60. The impression 60 is made, in particular of rigid or semi-rigid thermoplastic material, from a 3D printer. or by direct molding of the area to be makeup, for example plaster, alginate or silicone. Then a substrate 2 is fixed by a frame 6 on the support 20 and the device 1 is assembled to a printer to deposit an ink layer 4 on the transfer surface 3. When printing, the transfer surface is flat and held in position 30 with a substrate holder 12. Fig. 5B shows the device after printing, once separated from the printer. In a first configuration, the device has an air-filled space E between the cavity 60 and the face of the elastomeric substrate 2 opposite to the transfer surface 3. The substrate 2 has a flat transfer surface 3 at the time of transmission. impression. Alternatively, the space E is filled with compressed air or other fluid and the transfer surface has a domed appearance comparable to an air chamber. The substrate holder 12 is then removed, for example manually, and the air present in the space E is sucked by deformation means 25 not shown. The substrate 2 is thus deformable between the first configuration and a second configuration corresponding to the transfer of the ink to the zone to be made up, in which the substrate 2 is thus pressed against the imprint 60 and the transfer surface takes the form of the zone P to make up as illustrated in FIG. 5C. The device is then approached with keratin materials to bring the transfer surface 3 into contact with the zone P to be made up. Figure 5D illustrates the contacting of the device 1 having a frame 6 of rectangular section with the cheeks and the nose. The device of FIG. 5E differs from that of FIG. 5D in its shape. Figure 5F shows the transferred makeup. The invention allows a precise makeup, reproducible, easy to apply despite its complexity. Support 2 carrying substrate 3 and substrate holder 12 is assembled with a food-grade ink jet printer allowing printing on non-planar objects to print a layer 4 which reproduces a cosmetic ink pattern on the transfer surface. In the variant shown, the frame 12 serves both to fix the substrate 3 on the support 20 and the holding system 250 of the device 1 with the printer 500. In a variant only the frame 6 with the substrate 2 and the door Substrate 12 is configured to be assembled with a printer, for example introduced into a printer 500. FIG. 6 shows an exemplary embodiment of a cosmetic assembly 10 according to the invention. This comprises, within the same package, a plurality of devices 1 and 1 according to the invention differing in the type or form of the support 2.
[0035] In the illustrated example, each of the devices has on its transfer surface 3 a layer of coloring ink 4 forming a pattern 40, inverted with respect to the desired pattern. The package can be sealed to prevent drying of the inks. The packaging may be carried out with means to prevent contact of the inks with a surface other than the transfer surface, so as to reduce the risk of premature transfer. For example, the packaging comprises a thermoformed shell whose wall extends away from the transfer surfaces covered with inks. In addition, the devices 1 'having an imprint 60 are, for example, packaged in their second configuration, the substrate 2 being pressed onto the recess 60. FIG. 7 shows an alternative embodiment of a cosmetic assembly 10 according to the invention, which comprises a plurality of devices 1 and 1 'according to the invention, differing from the The first device 1 comprises a substrate 2 with a transfer surface 3 to be printed by the coloring ink, the substrate 2 being pressed onto a support 2 in the form of a roller 200 and a handle 80 also serving as holding means 250. The assembly 10 comprises for example a plurality of rollers 200 and a buffer holder 350 according to the invention. A first roll 200 is for example assembled to a handle e 80 can serve as a holding system 250 on a printer as seen above. The cosmetic assembly 10 comprises several rollers 200 arranged to carry substrates 2 of different thicknesses. All the rollers 200 of the assembly have the same diameter D, measured with the substrate fixed on the roll. Each empty roll diameter 200, i.e. prior to fixing the substrate, corresponds to a thickness e of substrate such that the transfer surface of the device defines a cylinder of diameter D, in particular of 60 mm. diameter. As illustrated in FIG. 11, the thickness e and the diameter d may vary along the longitudinal axis of the roll. Each roll 200 comprises a substrate 2 with a transfer surface 3 intended to be printed by the coloring ink, the substrate 2 being in particular plated on the roll.
[0036] The cosmetic assembly 10 also comprises a buffer support 350 adaptable to the holding means 250 as well as several buffers 300 and an elastomeric film strip to cut and stick as a substrate on the pads. Several devices 1 'have a footprint 60 corresponding to different areas to make up. The devices do not comprise an ink layer and the cosmetic assembly 10 comprises, within one and the same package, a printer cartridge 21 comprising one or more cosmetic dye (s) intended for ) to be deposited on the transfer surfaces 3 and deformation means 25 for pressing the substrates 2 on the cavities 60. In a variant not shown, the set comprises several cartridges, for example containing different inks. This cosmetic assembly can be provided to the user, if necessary, with the printer intended to use the cartridge. An example of a make-up method according to the invention will now be described with reference to FIG. 8. The method may comprise a step 111 of selecting a device adapted to the zone to be made up and to the pattern chosen from among a range of devices according to the invention. When the area P to make up has reliefs, the device 1 used preferably has a footprint 60 corresponding to said reliefs.
[0037] A makeup process according to the invention may thus comprise a preliminary step 110 of producing the impression. The impression 60 is made during step 110, for example by molding directly on the zone P of the keratin materials or by 3D printer and image processing.
[0038] In one variant, the impression 60 is fixed and intended to be used several times, in particular for a specific area of the keratin materials of a particular user. In another variant, the imprint can be modified and personalized before each make-up by transfer and thus adapt very modularly to the change of user and / or zone to make up. The method comprises printing a pattern to be transferred, and may also include steps 100 to 103 of choosing the pattern.
[0039] In a first step 100, different patterns are proposed to the user, for example by displaying on a screen of a device. The range of patterns proposed may correspond to several makeup areas requiring several different transfer devices.
[0040] The step 101 of choosing the pattern by the user may include an action such as pressing a touch screen to select the pattern to be printed. The apparatus may further provide the user with a simulation of the makeup result. Thus, the apparatus may display a simulation of the appearance of the keratin materials made up with the chosen or realized pattern. To do this, the apparatus 10 can acquire at least one image of the keratin materials to be made up. In a variant, the user makes a computer file with the pattern that he wishes to print. In this case, the user can use a drawing software to make such a pattern, and edit for example a file format image jPg. Once the pattern has been selected or realized, in step 102, the apparatus sends the printer the data necessary to print the pattern, in particular the device to be used. This may comprise a footprint made especially according to the area to be made up in step 110 or selected from a range of devices in step 111. The device is then in step 103, at least in part, assembled to the printer. Depending on the selected device all or part of the device is assembled to the printer through a holding system, for example the substrate and the substrate holder are attached to the printer. In a variant only the frame, the substrate and the substrate holder are attached to the printer. The apparatus can be physically connected and / or through a network to the printer performing the printing. Once the data received and the support, or even the complete device, assembled to the printer, in step 103 the pattern is printed inverted on the transfer surface 30 while the device is at least partially assembled to the printer. Figures 1C and 5B illustrate patterns thus printed on the transfer surface of different types of devices according to the invention.
[0041] The printer driver may include a menu for selecting a cosmetic ink cartridge from other cartridges in place in the printer and / or the nature of the substrate being printed. Alternatively, the printer automatically recognizes that the cartridge in place is a cosmetic ink and adjusts the operating parameters accordingly. The cartridge may thus comprise an identifier, for example an electronic chip, making it possible to supply the printer with information relating to the nature of the coloring ink that it contains, in particular that it is of a cosmetic nature. In an exemplary embodiment, the printer is configured to prohibit printing if the assembled device does not match the chosen pattern and / or the presence of a cartridge having a composition not intended to be in contact with the materials. human keratin, including skin, nails or lips, is detected. In a variant, the printer can perform printing even if the presence of a cartridge comprising a composition that is not intended to be placed in contact with human keratin materials, in particular the skin, the nails or the lips, is detected. non-cosmetic ink that can be used to print on the substrate an indication 7 relating to the cosmetic coloring ink carried by the transfer surface and / or the nature of the keratinous materials to be made up. Substrate printing can be done in multiple passes to effect successive ink deposits at the same location to increase the amount of ink deposited on the substrate. The substrate may for example carry out between 1 and 20 passes in the printer and the amount of dry matter of cosmetic ink deposited is, for example, from 0.1 mg / cm 2 to 10 mg / cm 2, better still 0.2 mg / cm 2 at 5mg / cm2. The pattern can be monochrome or, better, polychrome. In this case, one can print each pass through the printer with several cosmetic inks that are locally juxtaposed at the microscopic scale, depending on the color to be reproduced. The resolution of the print can be between 16 dpi and 2048 dpi. In a manner known to those skilled in the art, the printer can be arranged to detect whether the ink previously deposited on the substrate is sufficiently dry before printing a new ink layer. The printer and / or printer driver may be constructed to inform the user of the need to wait for a predefined time before re-printing the previously printed substrate. The printer and / or driver can automatically suspend the printing of a previously printed substrate until sufficient time has elapsed to induce sufficient drying. The printer is preferably arranged not to deliver the printed substrate until all the layers of ink to be printed have been. The device is then optionally separated from the printer so that the ink can be transferred to the keratin materials. In the case of an impression made on a substrate fixed on a support disengaged from the rest of the device, during a step 104 the device is reassembled, the frame is in particular repositioned on the support. The substrate is for example fixed on the support in a first configuration corresponding to FIG. 5B. When an embodiment of device with imprint 60 is used, before carrying out the transfer of the coloring ink to the keratin materials, the substrate 2 is pressed against the support 20 under the effect of a mechanical action of the means deformation during a step 120 to take a second configuration as shown for example in Figure 5C. It may be possible to first remove any substrate holder 12 and / or a protective film which has not been removed earlier in order to preserve the stability of the printed pattern, especially until the substrate is stamped onto the impression. Then the substrate 2 is then deformed under the action of deformation means 25, in particular suction means 75 of the fluid 25. For a device 1 corresponding for example to an applicator roll such as that of FIGS. 1A-C, the plating of the Substrate on the support is made prior to depositing the coloring ink on the transfer surface 3. The substrate 2 is in this embodiment directly plated on the support 20 and step 120 is superfluous. The transfer is done in step 130 by simple contact of the transfer surface 3 with the keratinous materials P, in particular by rolling the device on the keratin materials in the case of a device in the form of a roller 200 as illustrated in FIG. Figure 3, or application of the imprint 60 covered substrate 2 as in Figures 5 D and 5E. The transfer is facilitated by a pressure of the device against the keratin materials during step 130.
[0042] Step 130 may be preceded by a step 131 of finishing the pattern on the transfer surface. This finishing step of the pattern deposited on the transfer surface can be done with the fingers and / or a special tool or with a geometric grinding system. For example, pressure is applied to certain regions where certain regions are heated. Step 130 may be followed by a makeup finishing step 132. Step 130 may include heating the device. FIG. 9A illustrates an alternative device according to the invention before fixing the substrate on the support. The illustrated device comprises a handle 80 similar to the handle of the system of FIGS. 1A to 1C. This handle 80 can be used with several different rollers 200, adapted to different thicknesses of substrate and different modes of attachment. Whereas the substrate of the embodiment of FIGS. 1A to 1C was frictionally fixed to the support, a device according to the invention may comprise a means 25 for fixing a printing substrate on the support 20. The locking means 25 illustrated in FIG 9A comprise a groove 21 on the outer surface of the roller, a double gripper 22 whose opening is controlled by cams located at each end of the roller 200 and a system of springs, not shown, for keep the double clamp closed. In the example illustrated in FIG. 9B, the fastening means 25 of the substrate on the roll comprise a fixing jaw 26 arranged to be fixed, for example by screwing, in a housing 24 of the roll, keeping the substrate in position. The empty diameter d of the roll 200 is chosen to correspond to the thickness e of the substrate so that once the substrate 2 is positioned, the transfer surface 3 forms a cylinder of diameter D, for example equal to 60 mm. FIGS. 7A to 7D illustrate a buffer holder 350 intended to be assembled to a holding system 250, in particular to the handle 80. These figures illustrate, for example, a buffer holder 350 according to the invention that can simultaneously receive three buffers. A substrate 2 is adhered to the outer surface of each pad 300; the substrates 2 are, for example, cut from an elastomeric film bonded to the support.
[0043] In the examples of Figures 10A to 10D, a buffer support 350 has been added to the handle 80 of a holding system 250 in place of a roll. In a variant not illustrated, a buffer gate is configured to receive a single buffer.
[0044] A buffer support can accommodate for example between one and five buffers. Preferably, the buffer support 350 and the buffers 300 are configured so that the transfer surfaces of the pads belong to a cylindrical envelope surface, in particular 60 mm in diameter. FIGS. 10A to 10D illustrate various devices according to the invention comprising a support in the form of a buffer. The system 10 of FIG. 10A comprises a single device 1 in the form of a buffer, here illustrated, fixed on the holding means. Fig. 10B shows the same system, the buffer device being isolated from the holding means. The device comprises a handle member 85 in the form of a handle terminated by a square end piece 81 enabling it to be fixed in a housing 351 of the buffer support 350. The buffers may correspond to a portion of a cylinder, for example defined by an angle of between 100.degree. and 2100. The cylinder part is in particular between 1/10 and 4/5 of cylinder, in particular between 1/5 and 3/4 of cylinder, or even corresponds to a quarter cylinder or a half cylinder. Thus the buffer 300 illustrated in FIGS. 7A and 7B has a transfer surface 3 of oblong and cylindrical shape along its major axis, corresponding to an angle α of 100. FIG. 7C illustrates three buffers 300 whose transfer surface is a portion The buffers 300 shown in Figures 10A and 10B have an outer surface of oblong and cylindrical shape along their major axis. In Figure 10C, there are shown three buffers whose outer surface is a cylinder portion. The buffers of FIG. 10C are of oblong and cylindrical shape along their minor axis. The device variant of FIG. 10D comprises three spherical plugs.
[0045] In variants not shown, the outer surfaces of the buffers 300 are flat. In another example not shown the substrate fixed on the pad is pre-molded. A substrate 2 is adhered to the outer surface of each pad 300; the substrates 2 are, for example, cut from an elastomeric film bonded to the support. The handle 80 may include a rotational locking device 320 of the roller 200 or the buffer holder 350. EXAMPLES Example 2) (FIGS. 5C and 8) In this example, the roller is full, and hourglass-shaped. The empty diameter d in the center is 20 mm smaller than at the ends. An elastomeric silicone coating is molded around this roll so as to give the roll a cylindrical shape with a diameter D equal to 60 mm. The central portion of the substrate is softer than the side portions, making this type of roller particularly suitable for bump body areas such as the chin or arms. Example 3) for transfer-arm makeup An alginate composition was applied to one arm over a length of 20 cm and a width of 8 cm. After caking, roll the impression that has just been made so as to touch the two ends. The result is a flexible object in the shape of an hourglass. A mold is made from this object in two parts. The two parts of the mold are opened to remove the flexible object made with the impression. Then, a molded resin composition is introduced into the two parts of the mold through a hole. After curing, the molding of the mold is released. Then proceed as in the previous example by applying a flexible elastomeric composition so as to achieve a cylinder. This roller is specially adapted for arm printing. These examples correspond to the embodiment with a roller. A Canon IP 100 printer is used: The printer housing has been removed. While leaving the gears usually used to rotate the drive roller, the sheet drive roller system has been replaced by a drive system arranged to rotate a media in the form of a printing roll in such a way that synchronized with the scanning of the print nozzles. The printing roll of Example 1 is solid and cylindrical with a diameter of 60 mm and a length of 80 mm. it is made of Delrin-type hard plastic and covered with a substrate 2 formed of a 2mm thick silicone elastomer film. Upon printing, the printing roll is removably attached to the printer by a holding system as described above, to approach the printing nozzles (distance of about one millimeter ) and obtain a satisfactory print quality. The sheet presence system has been modified to not prevent printing from working. The body of the printer used has feet that allow it to be elevated to ensure the free rotation of rolls of different sizes while avoiding its friction on a portion of the printer. After printing, the device is removed from the printer to bring it into contact with the area to be made up. The roll of this example is particularly suitable for large relatively flat surfaces such as the back. Example 2) This example corresponds to the embodiment illustrated in FIGS. 1 to 3. The support is a regular cylindrical applicator roll 5 cm in diameter on which a 5 mm thick printing blanket substrate is plated. made of an elastomeric material, for example distributed under the name Patsie GEL 10 by Polytek. The applicator roll is assembled to a Canon 1P 100 printer adapted as described above for printing on such a roll. After printing, the system is removed from the printer to bring it into contact with the area to be made up.
[0046] The contact transfer of the roller is fast, easy, accurate especially on the nails, the cheeks. Example 3) This example corresponds to the embodiment illustrated in FIGS. 9C and 11.
[0047] In this example, the roller 200 is full and hourglass-shaped with a diameter of 20 mm dia empty peta in the middle of the roll at the ends (60mm diameter at the edges and 40mm in the center). An elastomeric silicone coating is molded around this roll so as to give the roll a cylindrical shape with a diameter D equal to 60 mm.
[0048] The central part of the substrate is softer than the lateral parts, which makes this type of roller particularly suitable for bump body areas such as the chin or the arms. Example 4) An alginate composition was applied to an arm portion to be enamelled over a length of 20 cm and a width of 8 cm. After caking, roll the alginate impression that has just been made so as to make touch both ends. The result is a flexible hourglass-shaped object from which a two-part mold is made. Then, through a hole is introduced between the two parts of the mold a polymerizable resin composition to produce an hourglass-shaped roller 20. After curing, an hourglass-shaped object is released which can serve as a support for a roll-shaped device. Then proceeding as in the previous example by plating an elastomeric substrate so as to produce a roller specially adapted for transfer to a portion of the arm. Example 5) A plaster impression is made forming a counter-mold of the area of the substrate. Then, the frame is surrounded by a support bearing a substrate in the form of a blanket of 2 mm thick printing. for example, an elastomeric material as used in Example 1. The device is then assembled to a Gatocopy A426 food ink jet printer with a cosmetic ink cartridge.
[0049] After printing, an internal substrate plate is removed (by unclipping the system holding the plate). The suction is then carried out, which will press the substrate against the impression and the whole is applied to the Peel zone. Then, the air is allowed to enter the system. The blanket returns to its original shape and the substrate plate is again placed. We can then make a new impression. EXAMPLE 6 In accordance with the preceding example, a plaster impression is made forming a counter-mold of the area of and then the frame of a support carrying a substrate in the form of a blanket of 2 mm thick in an elastomeric material. In this variant, no substrate holder is used, but air is injected into the space between the cavity and the substrate, which creates an overpressure causing the substrate to swell. The device is then assembled to a Gatocopy A426 food-grade inkjet printer equipped with a cosmetic ink cartridge. We print on the transfer area. The overpressure favors the quality of the printing, the nozzles of the printer being for example located at a distance from the transfer surface of between 2 mm and 5 mm. After printing, the device is moved away from the printer and then sucked off. 20 to press the substrate against the imprint and the whole is applied to the area of the ink transfer is by simple contact. After transfer, the device is removed from the zone of keratin materials and air is then allowed to enter the system. The blanket can be easily removed for cleaning before being put back in place for a new print.
[0050] The characteristics of the different exemplary embodiments can be combined with one another, within non-illustrated variants. The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
