PHOTOGRAVURE ENGRAVING ROLL AND METHOD FOR MANUFACTURING THE SAME

摘要

This invention provides a novel photogravure engraving roll, which is provided with a surface reinforcing covering layer free from toxicity and having no possibility of the occurrence of pollution and, at the same time, has excellent printing durability, and a method for manufacturing the same. The photogravure engraving roll comprises a plate base material, a copper plating layer provided on the surface of the plate base material and having on its surface a number of gravure cells, an adhesion layer provided on the surface of the copper plating layer, and a diamond-like carbon film covering the surface of the adhesion layer. The adhesion layer and the diamond-like carbon film are formed by CVD.
