METHOD FOR ENGRAVING IMAGES WITH RADIATION ON A RADIATION SENSITIVE LAYER, ESPECIALLY FOR LASER ENGRAVING

摘要

The invention relates to a method for engraving images into a radiation-sensitive layer by means of radiation, in particular for laser engraving. The layer is irradiated point by point such that a blackening (Sist(Pi,k)) is achieved for an image point (Pi,k), said blackening corresponding to a grayscale specified for said image point (Pi,k). In order to allow high-quality images to be engraved in a single engraving pass, the achieved blackening (Sist(Pi,k)) is ascertained for the image point (Pi,k); the difference (DeltaSi,k) between the ascertained blackening (Sist(Pi,k)) and a specified blackening (Ssoll(Pi,k)) is calculated; and the difference (DeltaSi,k) is divided between at least two adjacent image points (Rhoi,k+n; Pi+n,k+m) which are yet to be irradiated.
