Process for preparing ink jet system printing plate

摘要

A process for preparing an ink-jet system printing plate, wherein in a planographic printing plate precursor having an image receiving layer containing zinc oxide and a binder resin on a water-resistant support,the surface of the image receiving layer has a water-contact angle of 50° or more, andimage formation is carried out according to a hot melt type ink-jet system by heat melting an ink composition that is solid at ordinary temperature and spraying the droplets of the ink composition in a heat melt state from a nozzle onto the image receiving layer, and a nonimage area of the image receiving layer is then subjected to a desensitizing treatment by a chemical reaction to prepare a planographic printing plate.
