METHOD FOR ENGRAVING IMAGES BY MEANS OF RADIATION INTO A RADIATION-SENSITIVE LAYER, IN PARTICULAR FOR LASER ENGRAVING

摘要

The invention relates to a method for engravingimages by means of radiation into a radiation-sensitivelayer, in particular for laser engraving, in which theradiation-sensitive layer is irradiated in a point-by-point manner in such a way that the predeterminedblackening for each dot (P[err]) is obtained for thelatter. In order also to be able to use a relativelysimple radiation source, that is to say for example alaser system whose laser beam is subjected tocomparatively large power fluctuations, during theengraving of images, in particular during laserengraving, the invention provides for the blackeningobtained in each dot (Pkl) to be determined, and,during the subsequent irradiation of dots (P[err]), forthe radiation energy to be set as a function of soughtand obtained blackening.(Fig 1)
