Data carrier comprising a gravure printed image and methods for transposing image motifs into linear structures and onto a gravure printing plate

摘要

The invention relates to a data carrier printed by line intaglio having a halftone image represented by irregular line structures in the manner of an engraving. The line structures are superimposed at least partly by fine structures rendered in positive and/or negative representation. The invention-also includes methods for generating and processing the irregular line structures as digital image data on a computer following individual specifications by an operator. The line structures are transferred to a line intaglio printing plate, the digital image data being used for controlling an engraving apparatus, or, if other printing processes are applied, superimposed at least partly with fine structures rendered in positive and/or negative representation.
