Abstract
The invention relates to a printed data carrier having a printed surface and at least one printed partial surface enclosed thereby on all sides, the surface and the partial surface being printed by intaglio printing and contrasting visually due to an ink layer of varying thickness. The invention likewise relates to the method for producing the data carrier, the printing plate used therefor, and the method for producing the printing plate.
Claims21
A data carrier, in particular bank note, paper of value or the like, having at least one printed surface (13) and at least one partial surface (14) largely enclosed by said surface, wherein the surface (13) and the partial surface (14) are printed by intaglio printing, the two surfaces having different ink layer thicknesses and being distinguishable from each other.
A method for producing a printed data carrier, in particular bank note, paper of value or the like, wherein a substrate is printed by intaglio printing, ink is applied in varying ink layer thickness in one printing operation to a surface and at least one partial surface enclosed thereby so that surface and partial surface are distinguishable visually from each other.
An intaglio printing plate with depressions provided for receiving ink in the surface thereof, characterized in that the surface (13) taken up by a depression completely encloses at least one partial surface (14), and the partial surface (14) has an engraving depth that differs from the engraving depth of the surface (13), and the partial surface (14) is at least partly enclosed by a tapered separation edge.
A method for producing an intaglio printing plate wherein depressions provided for receiving ink and forming a surface are engraved into the surface of the plate, characterized in that at least one partial surface completely enclosed by said surface is produced, and the engraving of the partial surface is effected with a different engraving depth from that of the enclosing surface, and the material of the printing plate is removed by the engraving such that a tapered separation edge at least partly enclosing the partial surface is left standing in the depression.
