A method for engrave of images by means of radiation in a radiation-sensitive layer, in particular for laser engraving

摘要

The invention relates to a method for engrave of images by means of radiation in a radiation-sensitive layer, in particular laser engraving, in which the layer is irradiated at points, so that, for a pixel (p_{i, k}) a blackening (s_is(P_{i, k})) a is achieved, which for this image point (p_{i, k}) predetermined gray level corresponds to. In order in a single engraving passage high quality images to be able to engrave, it is provided that for the image point (p_{i, k}) the achieved blackening (s_is(P_{i, k})) is determined, the difference (δs_{i, k}) between the determined blackening (s_is(P_{i, k})) and a predetermined blackening (s_should(P_{i, k})) is calculated, and the difference (δs_{i, k}) on at least two still to be irradiated, of adjacent pixels (p_{i, k + n}; P_{i + n, k + m}) is distributed.
