VERFAHREN ZUR ERZEUGUNG VON EIN RASTERBILD DARSTELLENDEN MUSTERN

摘要

The method involves generating a set of patterns (10) with lines and curves adjusted in dimensions to produce tone variations restituting half-tones of an image. Another set of patterns (20) with microstructures distinct from the lines and the curves is generated, where the microstructures are adjusted in dimensions to produce tone variations restituting half-tones of the image. The patterns are interlaced such that the microstructures occupy spaces between the lines and the curves, and the half-tones restituted by the patterns (20) complete the half-tones restituted by the patterns (10). Independent claims are also included for the following: (1) a method for producing a half-tone printing plate (2) an engraved plate comprising patterns representing a half-tone image.
