ORIGINAL PLATE FOR DIRECT DRAWING TYPE PRINTING

摘要

PROBLEM TO BE SOLVED: To provide an original plate for direct drawing type printing that allows a printed matter having a clear image free from surface stains and image lacking/distortion or the like to be printed in a large quantity.

SOLUTION: In the original plate for direct drawing type printing, a liquid resin is absorbed by an aluminum substrate provided with numerous pores on the surface by electrochemical etching and at the same time a water absorbing and water resistant receiving layer is applied thereupon. Thereby, a part of the material forming a receiving layer to be applied is intruded into the pores formed by the electrochemical etching to form fine gaps in the pores.
