Definitions

the invention relates to a method for producing a data carrier with printed image produced by intaglio printing, with adjoining color surfaces of different ink layer thicknesses, as well as printing plates for carrying out the gravure printing method and a method for producing the printing plates.
Characteristic of the gravure printing technique is that in the printing, i. ink-transferring areas, the material of the surface of a printing plate by means of a suitable engraving tool or by etching is removed. Paint is applied to the finished printing plate and the excess printing ink is removed from the surface of the printing plate by means of a doctor blade or wiping cylinder prior to actual printing so that the ink remains only in the depressions. Then a substrate, usually paper, pressed against the printing plate and withdrawn again, wherein the color adheres to the substrate surface and forms a printed image. If translucent colors are used, the thickness of the paint application determines the color tone.
the line or intaglio printing technique in particular the Stahlstichianadrucktechnik is for the printing of data carriers, in particular of securities, such as banknotes and the like, an important technique.
the intaglio technique allows in comparison to other common printing techniques, such as offset printing, a very thick paint job on a disk.
the comparatively thick ink layer produced in the intaglio printing process can easily be recognized as a simple authenticity feature, even for the layman, by virtue of its tactility. This authenticity feature can not be imitated with a simple copy, so the intaglio technique offers protection against simple counterfeiting.
the intaglio printing is characterized by the fact that linear depressions are introduced into the printing plates in order to produce a printed image.
a wider line is produced with increasing stitch depth due to the usually tapered engraving tools.
the ink receptivity of the engraved line, and hence the opacity of the printed line increases with increasing stitch depth.
the non-printing areas of the printing plate are covered with a chemically inert lacquer. Subsequent etching produces the engraving in the exposed plate surface, the depth and width of the engraving lines depending, in particular, on the duration of etching.
Object of the present invention is therefore to provide measures that allow to create adjacent color areas in intaglio printing, which are clearly delimited from each other.
the ink areas on the printing plate associated engraving areas are separated by a separating edge, which tapers to a point at the level of the printing plate surface to produce adjacent color surfaces. If a data carrier, for example a banknote, is printed with such a printing plate, contiguous color areas are generated which pass through a minimum in the border area.
a data carrier for example a banknote
the color layer thickness at the boundary line between the color areas is zero.
the inks of the adjoining color areas in the immediate boundary area connect, it can be slightly greater than zero; this is especially true if the flanks of the separating edge are steep and have a small flank angle. The flatter the flanks of the separating edge, the slower is the ink layer thickness in the boundary region against the minimum ink layer thickness. This can be a very fine, only under magnification, for example, with a magnifying glass recognizable brighter borderline between the adjacent color surfaces are generated, which can serve as additional, hidden in normal view security feature.
the invention makes it possible for the first time to produce directly adjoining color areas with different layer thickness in the intaglio printing process, which do not run into one another and are clearly delimited from one another.
FIG. 1 shows a profile of a printing plate 1 with a printing plate surface 2, in which a first engraving area 3a with an engraving depth t a and a second engraving area 3b are engraved with a second engraving depth t b .
the two engraving areas 3a, 3b adjoin one another directly at the level of the printing plate surface 2 and, moreover, are separated from each other by a separating edge 5, the upper edge 6 of which tapers to a point at the level of the printing plate surface 2.
the flanks of the engraving areas 3a, 3b also simultaneously form the flanks of the separating edge and form a flank angle with respect to the solder on the upper edge 6.
flank angle ⁇ of the right flank of the separating edge is shown, since the two flank angles are the same in the example shown.
the two flank angles of the separating edge 5 can also be chosen differently.
the flank angles can be in the range of 15 ° to 60 °, preferably they are in the range of 30 ° to 50 °.
the base surfaces 7a and 7b of the engraving areas 3a, 3b may be flat (7a) or have a basic roughness pattern (7b).
the basic roughness pattern is advantageous because the ink is better kept at the bottom of the engraving.
the engraving areas 3a and 3b can also taper downwards so that they have no base area 7a or 7b (not shown).
the engraving depth ta, tb of the engraving areas 3a, 3b is in the range of 5 ⁇ m to 250 ⁇ m, and preferably in the range of 5 ⁇ m to 150 ⁇ m.
the engraved plates are also suitable for duplication by conventional impression techniques common in intaglio printing plates.
the engraved original is repeatedly reproduced via intermediate steps and only the reproductions are used as a printing plate. Engravings with the preferred flank angles and engraving depths have proven to be particularly beneficial in the impression and separation processes required during reproduction.
FIG. 2 is a section of a data carrier 10 with a two color areas 12a, 12b comprehensive print image shown schematically simplified.
the data carrier 10 was provided with a pressure plate 1, as in FIG. 1 shown, imprinted by intaglio printing. During the printing process, the data carrier 10 is pressed into the engraving areas 3a, 3b, wherein corresponding depressions 11a, 11b can remain permanently on the data carrier underside 17.
the data carrier top side 15 has corresponding elevations in the regions 11a, 11b, these elevations being covered by ink layers 13a, 13b, which were taken up by the data carrier top side 15 from the engraving regions 3a, 3b.
the color layers 13a, 13b form with their surfaces the color surfaces 12a and 12b.
the color layer thickness D a , D b is the level difference between the non-printed substrate surface and the surfaces of the respective color surfaces 12a, 12b set.
the ink layer thicknesses D a and D b decrease continuously to a borderline, which has been defined by the upper edge 6 of the separating edge 5 of the printing plate 1.
tb results in a more or less wide boundary region B. Since the ink layer thicknesses D a and D b in the boundary region B decrease continuously, can be selected by a suitable choice of the flank angle ⁇ one for the human eye without tools generate unrecognizable borderline of light shade.
the ink layer thicknesses D a and D b are reduced at the boundary line to a minimum ink layer thickness of thickness 0.
a small connection of the ink areas 12a, 12b take place, without, however, a detectable color mixing occurs.
the FIG. 3 shows this case. It can be seen that a connection of the color areas 12a and 12b has taken place at the boundary line 16.
the color layers 13 a and 13 b may consist of printing inks of different colors, since a mixing of the colors of different engraving areas due to the design of the printing plate according to the invention is practically not done. However, if the same translucent printing ink for adjacent engraved areas 3a, 3b b having different engraving depths t a and t, thus resulting in the printed image different color hues of the color layers 13a and 13b.
the adjoining engraving areas can be formed by line-shaped or area-like depressions.
the recesses are preferably engraved with a rotary stylus having a flank angle corresponding to the flank angle of the separating edge to be generated.
the engraving stylus can also be moved along tracks that form two coulters.
the curves or straight lines of a flock run parallel to each other and intersect the curves or lines of the second flock at regular intervals. This creates a basic roughness pattern in the manner of a cross grid with particularly favorable color catching properties.
the stylus is tapered or has a particular contour that allows to create on the base of the engraving a RautechniksgroundGerman that serves as a color catch.
the stylus is moved at regular, short intervals parallel to a previously engraved path, so that the previously engraved recess is widened by just this distance.
the engraving depth is in the range of 5 to 250 microns, preferably 5 to 150 microns.
flank angles in the range of 30 ° to 50 ° allow a longer life of the engraving tool with excellent printing results of the engraved printing plate.
Tools with flank angles in the range of 30 ° are particularly suitable for engraving very fine, filigree and small-area structures, while tools with flank angles of 40 ° to 50 ° are preferable for engraving large-area and coarser structures.
One or more line-shaped or area depressions may represent a pattern, an icon, or a character.
Several adjoining depressions can form a regular grid, so that the generated print image appears homogeneous, wherein the grid produces a fine structure in the print image, which can only be recognized with magnifying aids.
