Abstract

The prodn. of a printing plate by photogravure using flat, relief or intaglio screen positions comprises (a) exposing a photosensitised carbon- or pigment-paper while in contact with a white line gravure screen with the desired number of lines, (b) exposing the carbon paper additionally in contact with a flat relief or intaglio screen printing position, (c) exposing the carbon paper by means of a light scattering layer inserted between the carbon paper and the screen position and (d) transferring the carbon paper to a gravure cylinder and carrying out the etching process.
