A DATA CARRIER WITH A HALFTONE IMAGE PRINTED BY LINE INTAGLIO AND A METHOD FOR CONVERTING A PICTURE MOTIF TO A LINE INTAGLIO PRINTING PLATE

摘要

The invention relates to a data carrier printed by line intagho 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 arc applied, superimposed at least partly with fine structures rendered in positive and/or negative representation.
