Electrophotographic method for producing photopolymer printing plate

A method of producing a photopolymer printing plate comprising the steps of

• (a) forming a powder image on a photoconductive medium electrophotographically,
• (b) transferring the powder image from the surface of the photoconductive medium directly onto a photopolymer printing plate by bringing the powder image bearing surface of the photoconductive medium and photosensitive resin layer surface of the photopolymer printing plate into close line contact with each other under a uniform pressure in the range from 1 to 40 Kg/linear cm of line contact and applying a rolling motion therebetween at a speed in the range from 1 to 10 cm/sec. and sufficient to cause an adhesion of the powder image onto the photosensitive resin layer surface of the photopolymer printing plate,
• (c) exposing the entire powder image bearing surface of the photopolymer printing plate to a light, and
• (d) applying solvent material to the exposed photopolymer printing plate thereby forming surface differentiations therein corresponding to the powder image.
