Abstract
A method and apparatus for direct production of photopolymeric printing plates. The method comprises forming a positive and/or negative image on a substrate by ink-jet printing with a photopolymeric ink composition, optionally preheated. The apparatus for carrying out the method of the invention comprises a rotatable drum adapted for retaining on its inner or outer surface the substrate to be printed; a carriage, displaceable axially in respect of the drum; a container for a photopolymeric ink composition; at least one nozzle communicating with the carriage for ejecting the photopolymeric ink composition; and a UV source located so as to expose the printed surface of the substrate to UV radiation.
