Intaglio printing method for printing adjacent color areas of different ink layer thickness, data carrier with printed image produced by intaglio printing, printing plate and method for producing a printing plate

摘要

A method for printing a data carrier by intaglio printing with a printed image having at least a first color surface (12a) with a first color layer thickness (Da) and at least one second color surface (12b) adjacent to the first color surface (12a) with a second color layer thickness (Db) wherein the color layer thicknesses (Da, Db) are different, and wherein the first and second color surfaces (12a, 12b) are directly adjacent to each other and separated from a sharp boundary line invisible to the naked eye, and the color layer thicknesses of both color surfaces (12a, 12b) passes through a minimum in the region of the boundary line, wherein a pressure plate is used which comprises a surface (2) and engraved in the printing plate surface (2) at least a first engraving area (3a) with a first engraving depth (ta) and at least one second engraving area (3b) adjoining the first engraving area (3a) with a second engraving depth (t b), wherein the engraving depths (ta, tb) are different, and between the first and second engraving areas (3a, 3b) a separating edge (5) is arranged, whose upper edge (6) at the level of the printing plate surface (2) tapers.
