Title:
METHOD OF PLATE MAKING AND PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2008/010393
Kind Code:
A1
Abstract:
A method of plate making in which while utilizing the characteristics of convenience and high productivity attained by inkjet process, there are improved the plate life and resolving power having been problems of inkjet process plate making, and in which realizing high hardening sensitivity, plate making can be accomplished by a simple apparatus with the use of low-viscosity inkjet ink. There is provided a method of plate making through the sequential procedure of applying a plate making ink onto a printing plate material according to an inkjet recording technique, irradiating the ink with actinic energy rays, evaporating the ink solvent and drying to thereby attain image forming and thus obtain a printing plate, characterized in that the plate making ink contains at least water, an actinic energy ray crosslinking compound capable of hardening with actinic energy ray irradiation amounting to 0.8 to 30 mass% based on the total mass of the ink and resin microparticles of 5 to 150 nm average particle diameter amounting to 0.1 to 7 mass%.
