Beschreibung
Zusammenfassung:	The invention relates to a system for manufacturing an engraved plate for intaglio printing of sheets of security papers, said system comprising a computer and at least one engraving tool controlled by said computer in accordance with a programmed engraving process, wherein said computer is programmed to control the engraving tool in accordance with three-dimensional guiding pixel data (X, Y, Z) of a master depth-map of one said sheet to engrave a non engraved plate pixel by pixel, and wherein said master depth-map is generated on said computer on the basis of at least one original depth-map stored on said computer, said original depth-map consisting of a three-dimensional raster image of at least a part of one said security paper. The invention also relates to a system and method for generating said guiding data.
