PLATE-MAKING METHOD

摘要

PROBLEM TO BE SOLVED: To produce a printing plate having a printing part showing excellent strength, resolution and oil sensitivity using an inkjet type plate-making method. SOLUTION: The plate-making method comprises steps of; an imaging liquid resin containing a plurality of monomers or oligomers being a photo-polymerizable component and a solvent being a non-photo-polymerizable component is adhered to a print original plate provided with a water absorbing and water resistant porous layer to form a desired image pattern; at least a part of a solvent is released from the image creating resin by infiltrating the solvent in the porous layer; and the image creating resin is cured by the photopolymerization.
