Definitions

  • the invention relates to a printing plate for full-surface printing of large areas in intaglio printing, a method for producing the printing plate and a data carrier with a large-area printing image produced in intaglio printing.
  • the engraving lines of the printing plate are filled with ink for the printing process.
  • the excess ink is removed from the printing plate using a wiper cylinder or a squeegee so that the engraving lines are filled with ink right up to the edge.
  • the separators provided between the engraving lines are cleaned in this step.
  • the data carrier to be printed usually paper
  • a pressure cylinder which has an elastic surface.
  • the data carrier is pressed into the engraving lines of the printing plate filled with ink and thus comes into contact with the printing ink.
  • the data carrier is removed, it pulls the printing ink out of the recesses in the engraving lines.
  • the print image produced in this way has print lines which vary in the thickness of the ink layer depending on the depth of the engraving.
  • intaglio printing If translucent printing inks are used in intaglio printing, light colors are obtained when printing on a white data carrier with thin layers of ink, and darker colors when printing with thick layers of ink.
  • the intaglio printing process can produce printed images with very large ink layer thicknesses. The resulting print images can even be felt manually when using correspondingly deep engravings. In contrast, by using correspondingly fine engravings, extremely fine, razor-sharp print lines are also possible.
  • the intaglio printing process can produce very high-quality printed images that are broken down into line structures, it has the disadvantage that larger continuous printing areas, i.e. Lines with a width of approximately one millimeter and more cannot be produced. This is due to the fact that when the colored printing plate is wiped in the area of large engravings, not only the excess ink is removed, but also ink from the engraving. As a result, the ink surface is lowered below the surface level of the printing plate in these engraving areas. Since the paper pressed into the engraved areas of the printing plate does not reach the color surface in all places, there are gaps in the print image that make the print unusable.
  • the invention is based on the knowledge that when the printing cylinder or the printing plate is wiped, disruptive wiping out of printing ink from the area of the engraving can be prevented if so-called separating webs are provided in the engraving which act on the wiping cylinder Prevent or keep ink as low as possible in the engraving of the printing plate. It is assumed that the wave consisting of excess printing ink, which is pushed from the wiping cylinder over the printing plate surface during the wiping process, also extracts color components from the engraving due to hydrodynamic effects. The separators obviously prevent the printing ink in the engraving from moving in the total volume and being pulled along with the ink wave of the wiping cylinder.
  • the dividers therefore divide a larger-area engraving into adjoining “chambers” or channels, which allow the printing ink to be removed perpendicular to the printing plate surface during the printing process, but not parallel to the printing plate surface during the wiping process.
  • the separators are preferably arranged transversely to the direction of rotation of the printing cylinder. In this arrangement, they evidently cause the ink wave to shear off during the wiping process and thus hydrodynamically decouple the printing ink located in the engraving from the wiping process taking place on the printing plate surface.
  • the separating webs In cases in which it is not possible to arrange the separating webs transversely to the wiping direction, the separating webs at least subdivide the large engravings and give them a functionality with regard to the wiping out of paint which is similar to that of finely structured engravings.
  • the engraving areas should preferably be provided with separating webs transverse to the wiping direction. For engraving lines that run along the wiping direction, this results in the engraving lines being subdivided into sub-sections.
  • the engravings running transversely or diagonally to the wiping direction are subdivided at least in the longitudinal direction of the engraving line, the separating webs preferably running parallel to the engraving edges.
  • the engraving not only consists of very wide engraving lines, but also contains large-area engraving elements that have similar dimensions in the x and y directions
  • Such a design of the dividers not only has the advantage that the function of the dividers is guaranteed regardless of the wiping direction, it also ensures that the dividers are given increased mechanical stability.
  • the height of the dividers can be varied within a relatively wide range. If the dividers end at the level of the pressure plate surface, make sure that the separator shape considered in cross section tapers in a wedge shape. This ensures that on the one hand the subdivision - the engraving into separate channels or chambers takes place in an optimal form, but on the other hand the sharp-edged dividers do not result in an interruption of the printing surface.
  • the cross-sectional shape of the separators can deviate from the wedge shape almost arbitrarily, i.e. can also be trapezoidal, rounded or designed differently. Since the upper edge of the dividers in this case is always arranged below the level of the printing plate surface and is therefore always covered with printing ink, the production of a continuous printing surface is ensured in any case.
  • Engraving depth a height, which is also referred to as amplitude below, of more than 50%, cause "notches" in the ink layer surface on the printing surface produced thereby.
  • the printing surface produced with such a large-area engraving is continuous with Color is printed, it thus has a surface relief that comes from the dividers.
  • the surface relief is particularly strong if the separating web amplitude is selected in the range from 75% to 100% of the engraving depth. With lower amplitudes, for example in the range of about 60%, this surface relief becomes increasingly weaker until it finally disappears completely at an amplitude of about 50%. If the value falls below 50%, printing errors in the form of gaps or misfires are increasingly to be expected, particularly in the case of deeper engravings, which render the print unusable.
  • the preferred engraving depth for the production of common print images turned out to be the range from 10 ⁇ m to 60 ⁇ m.
  • Engraving with a depth in the range of approx. 60 ⁇ m to 100 ⁇ m is particularly suitable for printing color layers with a saturated, opaque color impression.
  • the exact values vary depending on whether it is a light or dark color.
  • Engravings with a depth of 100 ⁇ m and more are particularly suitable for the creation of colored layer structures with a relief that is easily perceptible with the sense of touch.
  • the finer the fine structure of the printed surface represented by the surface relief the less it appears when viewed without aids (magnifying glass). This applies at least to fine structures that are on Separators with a distance of approx. 20 ⁇ m to 150 ⁇ m and wedge-shaped separator shape can be attributed. Separators with a distance of 150 ⁇ m to approx. 400 ⁇ m can already be seen with the unarmed eye, but in no way disturb the overall impression of the printed color area. If a trapezoidal cross-sectional profile is used instead of a wedge-shaped dividers, the notches present in the surface relief become wider, ie more flat. With structures of this type, a design influence on the surface to be printed is possible, for example by the grid formed by the separating webs also appearing as a design element.
  • the dividers are not grid-like, but in the form of
  • the lines of a two-dimensional line drawing are captured by a computer and the areas of each individual line are precisely defined.
  • an engraving tool such as a rotating stylus or a laser beam
  • the outer contour of these surfaces is first engraved in order to frame the surface cleanly.
  • the bordered area of the surface is then cleared using the same or a different engraving tool, so that the entire line is engraved exactly according to the line template.
  • both a certain roughness instead of a smooth surface
  • the separating webs according to the invention with any amplitude, different flank angle or precisely specified cross-sectional shape.
  • the separating webs should have a minimum amplitude of approximately 50% of the engraving depth for the function according to the invention. If this value is clearly fallen below, the printing ink adheres better to the base of the engraving than to a smooth base, but the printing errors mentioned at the beginning cannot be avoided with large-area engraving elements.
  • the invention offers completely new possibilities in the design of intaglio printing plates.
  • By using large-area engravings it is now also possible to produce engraving lines with a width of 1 mm to 10 mm and more, and this with ink layer thicknesses of 40 ⁇ m and more.
  • Continuous geometrical areas of a few square banners can also be implemented without problems in intaglio printing.
  • the fine structure of the printing surface can be in the form of a grid as well as in the form of letters or symbols. Even if the coarsest fine structure (separator spacing on the order of 500 ⁇ m) is selected, it cannot be imitated by any known printing process, which means that the forgery-proofness of the correspondingly printed one
  • Disk is increased significantly.
  • the fine structure thus not only demonstrates the use of the intaglio printing process, which is already high-quality per se, but also the use of the engraving device described in WO 97/48555, which is not available to any counterfeiters because of the high cost.
  • Fig. 1 shows a section of a printing plate 1, the surface 2 is provided with an engraving 3 of predetermined depth t, which is used to hold printing ink.
  • the engravings shown in cross section run in a line, perpendicular to the plane of the paper and are designed in such a way that separating webs 4 are present between the parallel depressions, the upper edge 5 of which lies at the level of the printing plate surface 2.
  • the separating webs 4 on the one hand, prevent the printing ink from being wiped out of the depressions formed by the engraving 3 and, on the other hand, structure the ink layer transferred to a substrate.
  • the substrate is printed all over with color in the area of the engraving.
  • the offset with which the parallel engravings 3 are produced corresponds to the distance d between the top edge 5 of the separating web 5.
  • the distance d is preferably in the range from 20 ⁇ m to 150 ⁇ m, a distance of approximately 50 ⁇ m being particularly preferred for the production of fine structure which cannot be recognized without aids.
  • the modulation of the ink layer thickness created by the separators creates a fine structure in the printed ink layer that cannot be resolved with normal observation with the naked eye and can therefore serve as a hidden security feature that cannot be reproduced by electrophotography or other printing methods.
  • the intensity of the color impression or the perceived color tone depend on the average color layer thickness and can be set by the engraving depth t for a given flank angle ⁇ .
  • a printing plate is shown in cross section, with which an on average thinner ink layer can be printed, which produces a lighter color tone.
  • the engraved areas of the printing plates shown in FIGS. 1 and 2 are of the same size and the engravings 3 have the same flank angle ⁇ . Due to the smaller engraving depth t in FIG. 2, a smaller distance d is chosen for the offset of the engraving lines. For the printing of coherent color areas, it is important that, taking into account the flank angle ⁇ , the engraving depth t and the distance d between the top edge 5 of the separating web are selected such that within an engraved area richly at the level of the printing plate surface 2 no flat plateaus arise.
  • the engraved area has the same extent as in the examples in FIGS. 1 and 2.
  • the engraving depth t is the same as in FIG. 1.
  • the separating webs 4 have a different flank angle ⁇ , one with a
  • the ink layer transferred according to FIG. 3 has the same average layer thickness as that printed with a printing plate according to FIG. 1.
  • surfaces with the same color tone are printed with the printing plates of FIGS. 1 and 3.
  • the printing plates according to FIGS. 2 and 3 have the same separator spacing d and thereby produce a fine structure of the same periodicity, but due to the different flank angles (.alpha., .Beta.) Lead to color layers of different average thickness and different tint.
  • the engravings 3 are preferably produced with rotating styluses, the tip angle of which, measured to the center line of the stylus, corresponds to the flank angle of the engraving.
  • the flank angles are preferably in the range from 15 ° to 60 °, the range from 30 ° to 50 ° is particularly preferred.
  • mechanical engraving tools have an increased service life.
  • Printing plates with the preferred flank angles are easier to reproduce using impression techniques and also have particularly favorable printing properties.
  • Wedge-shaped geometries are preferred as the separator shape (cross section). However, any other, in particular wave or sinusoidal, geometries are also conceivable.
  • the shape of the cross section of the dividers 4 is only limited by the design options for the contour of an engraving tool.
  • Structures such as are shown in FIGS. 4 and 5 are suitable for reducing the ink layer thickness in the transition area from one fine structure line to the adjacent one to a value other than zero.
  • An embossing plate according to FIG. 4 is produced by removing the ends of the separating webs pointing outwards after the engraving of the depressions forming the fine structure.
  • the entire area to be engraved can first be cleared at depth a and then the depressions forming the fine structure can be engraved.
  • the outward-facing ends of the separating webs are thereby lowered by the value a below the level of the pressure plate surface 2.
  • the remaining height of the separators is referred to below as amplitude b and results from the difference between the engraving depth t and the lowering of the separator a.
  • a substrate printed with such a printing plate is provided with a colored layer of thickness a in the area of the engraving, which is additionally modulated with a fine structure of maximum amplitude b.
  • the upper ends of the dividers which are designed as plateaus in this example, produce fine bright lines in the printed image. With appropriate guidance of the engraving lines producing the dividers 4, the bright lines generated by the trapezoidal dividers 4 in the printed image can reproduce patterns, characters or symbols.
  • a separating web lowering a can also be achieved in that, for a given flank angle and a given engraving depth t, the offset between the individual grains is so small that the top edge of the separating web 5 is below the level of the pressure plate surface 2.
  • a lowering of the separating web is advantageous because it prevents the plastic surface of the wiping cylinder from coming into direct contact with the sharp-edged dividing webs 4, thereby reducing wear and tear on the wiping cylinder surface and on the fine, engraved structures of the printing plate.
  • the lowering of the separating web a is preferably 2 ⁇ m to 5 ⁇ m below the level of the printing plate surface 2. In order to reproduce the engraving neatly as a fine structure of the transferred one
  • the amplitude b should be more than 50% of the engraving depth t.
  • the dividers 4 are arranged at a greater distance d.
  • the separator spacing d does not correspond to the offset of the engraving tool during the engraving of the depressions.
  • the distance d is preferably less than 500 ⁇ m.
  • horizontal bottom surfaces 6 of the engraving which have a specifically set surface roughness to improve the color adhesion. The surface roughness is set by selecting the geometry of the tip angle and tip radius of the engraving tool and by specifying suitable values for the offset between two engraving lines transverse to the engraving direction.
  • the engraving 3 is introduced into a printing plate surface 2 such that the engraving depth is not constant within the engraved area, but in one direction continuously increases or decreases (Fig. 7a, 7b).
  • the variation of the engraving depth is preferably carried out in such a way that the deepest points of each engraving line lie on a plane that is oblique to the printing plate surface. It is also possible to change the engraving depth so that the deepest points lying in a cross-sectional plane of the printing plate lie on a curved curve, the course of which can be described, for example, by a parabola above the hyperbola.
  • the variation in engraving depth allows the perceived color tone to be varied within a coherently printed color area, in particular if the depth variation is between 5 ⁇ m and 60 ⁇ m.
  • the separator spacing d and the height of the separators are constant throughout the engraving, while in the variant according to FIG. 7b the spacing and height of the separators increase with the engraving depth (di> d2).
  • a second engraving can be superimposed on a first engraving. If the first engraving is formed by parallel, preferably straight engraving lines and the second engraving also by parallel, preferably straight engraving lines, a so-called cross line grid is created. If the lines of the first and second engraving form an angle between 20 ° and 90 °, in particular from 40 ° to 70 °, the resulting engraving has particularly good color adhesion, which has a favorable effect on the printing properties of a correspondingly engraved printing plate .
  • the printed layers of color also have a particularly uniform color tone.
  • the first and the superimposed second engraving can be created with engraving tools of different geometry and with different engraving depth and / or different engraving line offset. In the case of the preferred cross line grid, this leads to periodically interrupted dividers.

Abstract

L'invention concerne des plaques d'impression destinées à l'impression complète de grandes surfaces selon le procédé d'héliogravure, un procédé de production de plaques d'impression et de supports de données, notamment de billets de banque, comportant des images imprimées réalisées sur une grande surface selon le procédé d'héliogravure. Pour garantir un encrage sans défaut, la gravure de la plaque d'impression présente des segments séparateurs qui s'élèvent perpendiculairement à partir de la surface de base de la zone de gravure et dont la hauteur représente au moins 50 % de la profondeur de gravure. Les segments séparateurs permettent d'éviter, dans une large mesure, que l'encre couleur ne soit enlevée de la zone de gravure lorsque l'on essuie l'encre couleur de la surface de la plaque d'impression. On peut ainsi recouvrir entièrement la surface d'une zone d'impression d'un support de données avec des couches d'encres. Une disposition et une conception particulières des segments séparateurs permettent cependant de produire des structures fines dans la surface d'impression qui, selon les écartements choisis entre les segments séparateurs, ne peuvent être reconnues qu'avec des moyens auxiliaires permettant un agrandissement.
