Abstract

A procedure for making a halftone printing flatbed printing plate, in which the copy layer of a photosensitive copy material, consisting of a copy layer carrier with a moderately rough surface and a photosensitive copy layer lying on top of said layer and containing at least one photosensitive organic compound and, eventually, a resin, is exposed homogeneously through a sample of halftones, subsequently revealing itself, characterized in that a photosensitive copying material is used, in whose copying layer a substance is contained light absorbing, which absorbs light in the same area of the light spectrum as the photosensitive compound.
