    [0002] Printing procedure and printed part
    [0004] TECHNICAL SECTOR
    [0006] The present invention relates to a printing process, especially for fiberglass and other similar materials, such as taffeta fabric, veiled fabric with and without sizing, as well as the piece so printed.
    [0008] The scope of the invention would be to manufacture fiberglass elements and covers, for example, surfboards, windsurfers, canoes, boats, shower trays, countertops, bathtubs, toilets, paddle tennis rackets, swimming pools ... . and all that element that is manufactured with this material.
    [0010] STATE OF THE ART
    [0012] Fiberglass printing is highly complicated, as it is not a material that absorbs ink correctly, and the existing machinery on the market today is not made to print this type of material. Consequently, printed images are of poor quality, when they require very high definition (dots per inch). In addition, the boundaries can be blurred, losing clarity. In general, a lot of print definition is needed to render high-quality images on this material.
    [0014] However, fiberglass is a highly versatile material for the construction of light and resistant elements, such as the hulls of boats, including surfboards. When you want to decorate these elements, for example, in a race or to incorporate the name of a sponsor, you have to paint or apply an outer layer (such as vinyl). This layer is exposed to damage and to lose its appearance, as well as to generate small residues as the outer layer wears or breaks. Furthermore, known procedures require extra manipulation of the glass fiber, causing its degradation. On the other hand, with the invention the impression is part of the structure of the manufactured part itself (table, racket, etc.).
    [0015] The manufacturer of the parts has the printed material, so you do not have to carry out any coating of paint, vinyls, etc. In addition, printing can be done in a controlled, more environmentally friendly way, without harmful solvents, mercury or lead. UV inks do not emit volatile chemicals and do not generate ozone.
    [0017] The applicant does not know of any procedure similar or equivalent to the invention, which allows to obtain comparable results.
    [0019] BRIEF EXPLANATION OF THE INVENTION
    [0021] The invention consists of a fiberglass printing method according to the claims. It also refers to the piece that comprises a layer of fiberglass or the like printed with the method.
    [0023] The printing process on layers of fiberglass or similar comprises the steps of:
    [0024] Fix the fiber layer on a rigid plate in a removable way.
    [0025] Eliminate static electricity or electrostatic charge from the fiber layer. This removal is preferably carried out on that rigid plate, but can be done on a previous auxiliary plate.
    [0026] Print using UV drying ink and illuminate immediately with UV light, for drying. In this way the ink does not move from the application point.
    [0027] Preferably remove static electricity from the fiber layer immediately after printing, prior to removing the fiber layer from the plate. This removal can be done at the point of manufacture of the finished part.
    [0029] Thanks to these stages, it is possible to print on fiberglass with full guarantees of quality and definition.
    [0031] Removing static electricity prior to printing provides several benefits, preferably print quality and definition. First, the ink exits the print nozzle electrically charged, therefore the presence of electrostatic charge in the fiber layer affects its path, usually spreading it, and reduces the definition of the print. In addition, the ink must penetrate the fiber layer to a measured depth, which is a function of the injection pressure, the characteristics of the mesh and the delay in illumination with UV light. The presence of electrostatic charge, which in each case will be different, it also affects penetration, preventing the printing from being properly configured.
    [0033] On the other hand, despite immediate UV light curing, the ink still takes some time to finish curing and can still be affected by the electrostatic charge of the material. For this reason, it is advisable to ensure that the charge provided by the printing is removed after it and that no new electrostatic charge is provided until the ink has cured.
    [0035] The process may comprise a previous step of eliminating the initial deformation of the fiber layer, especially if it is supplied with folds, folds or in a roll.
    [0037] The removal of electrostatic charge may comprise moving from the initial rigid plate to a secondary plate.
    [0039] The fiber layer can be attached to the plate in various ways, but in the most preferred embodiment it is adhered to the plate by a repositionable adhesive. In other words, an adhesive that allows the fiber layer to stick slightly (enough so that it does not move, but without having excessive gluing force). For example, the 3M® repositionable series. This adhesive is preferably conductive to reduce the electrostatic charge of the fiber layer, in the same way that the plate must be able to absorb that charge (because it is conductive and derived to ground, because it is made of a more capacitive material ...) .
    [0041] If the fiber layer has sufficient transparency, it is possible to place it on the plate with the back facing out and the printing is carried out in a specular way, that is, with the right and left reversed. The print quality is reduced, but the resistance of the paint layer is considerably higher, since it is on the inside face. As the quality of the process is high, the loss of definition is not so negative. This specular impression can be suitable for physically working parts and can be damaged by blows. These pieces can be repaired, which generally involves sanding which, in this case, would not affect the printed image. The loss of definition, contrast and vividness of the print is compensated by the increased durability.
    [0043] One way to ensure the proper placement of the fiber layer on the plate is to carry out a step of finishing the fiber layer using a felt or other utensil. soft and smooth material (cotton ...) and in a way that does not produce static electricity phenomena (antistatic)
    [0044] For example, you can use a graphite felt, or a traditional felt very softly. This grinding step can be performed before you finish eliminating static electricity.
    [0046] Preferably, printing is done in several passes by performing print-dry cycles immediately.
    [0048] The invention also relates to the piece comprising a layer of fiberglass that has been printed by the process.
    [0050] Other variants will be commented on in other points of the memory.
    [0052] DESCRIPTION OF THE DRAWINGS
    [0054] It is not considered necessary to present figures for the understanding of the invention.
    [0056] MODES OF EMBODIMENT OF THE INVENTION
    [0058] An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.
    [0060] The process of the invention starts from the layer of fiberglass arranged in a flat way. For this, if it is supplied in coils, the initial deformation of the coil must be eliminated. For example, by spreading it on a flat or counter-curved surface for a period of time, such as 30 minutes. The time depends on several factors (thickness, radius of the b or b in a.) So this indication is only approximate.
    [0062] The fiber layer is then placed on a rigid sheet, for example PVC. The fiber layer must be attached to the plate in an easily removable way. For example, a lightweight adhesive such as the repositionable series marketed by 3M® can be used. The plate will have, at least, the dimension of the image or text to be printed. Preferably it will be somewhat larger, so that the manufacturer of the back piece has room to register the shape well.
    [0063] Since fiberglass is a non-conductive material that can accumulate electrostatic charge or voltage, it is necessary to remove that charge. It can be done at the same time as the deformation is eliminated or in the final rigid plate. For example, you can run a roller or other grounded metal element across the entire surface of the fiberglass layer, make the rigid sheet conductive and grounded, use a rigid sheet of more capacitive material (e.g. example, foamed PVC), etc.
    [0065] It is important to calibrate the adhesion of the fiber layer to the plate to ensure that it is not damaged when released, or that it moves during printing. To ensure that the adhesion is correct, the fiber layer is placed with a small tension, which allows to avoid wrinkles and irregularities. If necessary, go over with a spatula, a rolling pin, etc. If the electrostatic charge has already been eliminated, it is recommended that this spatula or roller be made of felt so as not to add new electrostatic charges.
    [0067] This placement ensures perfect contact between the plate and the fiber layer, and that the weft that forms the fiber layer layer is relaxed and remains at its root, without distortions that would imply a reduction in quality.
    [0069] If necessary, the adhesive is allowed to dry before inserting the plate into the printing machine. The plate must be perfectly fixed to the machine to avoid small displacements. For example, if the machine includes a suction table, the suction will be regulated at the top of its conditions of use.
    [0071] The printing machine will use UV drying ink and will use UV lamps for immediate drying, avoiding ink runs. Preferably, several passes of the print heads will be made, performing print cycles - immediate drying. In this way, consistency is obtained, but without filling, definition and the maximum set in the fiber layer itself. The drop enters the fiber layer as a liquid and when it receives UV light it solidifies. On top of that drop the others are placed, in a uniform and staggered manner.
    [0073] Once the printing is finished, it is left to rest for the ink to finish setting. Preferably, ensuring that any new static electricity due to printing is lost. It is also possible to contact a grounded conductor to eliminate that static.
    [0074] Once the fiber layer is printed, it can be sent to the next point in the manufacture of the element. For example, it can be sent to the surfboard manufacturer, who will then be able to create completely custom boards. Shipping can be done on the plate itself to facilitate transport or delicately rolled.
