Title:
METHOD FOR PRODUCING PHOTOSENSITIVE LAMINATE ORIGINAL PRINTING PLATE FOR LETTERPRESS PRINTING, PHOTOSENSITIVE LAMINATE ORIGINAL PRINTING PLATE FOR LETTERPRESS PRINTING, AND METHOD FOR PRODUCING LETTERPRESS PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2007/004681
Kind Code:
A1
Abstract:
A mask pattern of high outline precision is formed on a photosensitive resin layer by a step of printing a predetermined pattern of a printing ink composition containing a light-blocking substance for absorbing light in a predetermined wavelength region and curable when receiving a predetermined energy on the photosensitive resin layer formed on a support and exhibiting a sensitivity to light in the predetermined wavelength region or on an intermediate layer formed on the photosensitive resin layer, and a step of forming a mask pattern by applying the predetermined energy to the print pattern to cure the print pattern. The problems when conventional negative films are employed in letterpress printing and when a mask pattern is formed of an ink composition directly on the surface of the photosensitive resin layer can thereby be solved simultaneously.
