      I,
    The invention relates to the printing industry, in particular to machines for printing securities, which can print both on sheets and on tape.
    The aim of the invention is to improve the print quality.
    The drawing shows a schematic diagram of the proposed machine.
    The machine for printing securities, in particular bank notes, contains a form plate 1, carrying at least one form of intaglio printing with printing elements for reproducing an image of the main pattern and more finely and finely engraved printing elements for reproducing an image of a background protective grid (in the drawing detailed not shown), printing cylinder 2 interacting with the plate cylinder, also interacting with the plate CYLINDrM CYLINDER
    a collector 3 with an elastic smooth surface, for example, made of rubber or other elastic material, positioned behind the collector cylinder 3 in the direction of rotation of the forme cylinder, the pattern roller 4, which is part of the device for applying ink to the image forms of the cylindrical image 15 which, along with the pattern-i roller 4, includes the means 5 for applying paint to it. The machine also contained patterned cylinders 6 for transferring a single-color paint and colorful means 7 on each of the printing plates to each printing unit, each of which is intended for applying paint to. the surface of the corresponding templating cylinder 6, which, together with the cylinder-collector 3, form a device for applying at least two inks to the reproduction. The drawing depicted the background of the protective grid printed form elements,
    In addition, Mapgin coderiste doctor blade device, including the main doctor device 7 and the means 8 dp pre-remove ink from the printing form.
    The template roller 4 has an elastic working surface and on its surface contours are cut out in relief, the contours of which exactly correspond to the contours of the printing surface.
    632
    parts of the shape that reproduce the main pattern.
    Template cylinders 6 are in contact with ts1, rum-collector 3 and have a working surface made of hard material, such as hardened rubber, plastic, or a meta map.
    In the presented embodiment of the proposed machine is used
    Three template cylinders are called, and each of them is contoured in such a way that there are relief areas on it, the contours of which correspond to the contours of the printing
    portions of the form that reproduce the elements of the background protective mesh. divided colors. These relief ceilings can be made by any known method, for example, chemical
    etched with a laser and
    etc. Since the surface of these cylinders is hard, there are no restrictions on the fineness of the lines of the pattern that they want to get. It is even possible to draw a pattern of a background protective grid not only from very thin lines, but also from points, which is impossible when using a known machine. When the ratio between the diameters
    templating cylinder 6 or templating roller 4, cylinder-collector 3 and the forme cylinder 1: 2: 3 are provided with three printing plates evenly distributed on the forma cy-
    LINDRE 1.
    Since the engraving that forms the background protective grid is very thin, it has a shallow depth, the force with which it is pressed against the surface
    plate cylinder 1 cylinder-collector 3 should be much weaker than the one with which the pattern roller 4 presses against the printing elements having a deeper engraving
    and forming the main figure. In this connection, although the surface of the cylinder-collector has some elasticity, its deformation does not occur, and the image transmits
    with perfect clarity. The force of pressing the patterned cylinders to the surface of the cylinder — KOJUieKTopa 3 is chosen to be small, thus avoiding the deformation of very thin
    relief areas on the surface of cylinders 6.
    To provide absolutely accurate registration between the template cylinder
