This invention provides a novel gravure platemaking roll, which has a surface enhanced covering layer free from toxicity and concern about the occurrence of pollution and, at the same time, has excellent printing durability, and a process for producing the same. The gravure platemaking roll comprises a plate base metal, a copper plating layer, which is provided on the surface of the plate base metal and has a large number of gravure cells on its surface and a silicon dioxide film covering the surface of the copper plating layer. The silicon dioxide film is formed using a perhydropolysilazane solution. Preferably, the thickness of the copper plating layer is 50 to 200 µm, the depth of the gravure cell is 5 to 150 µm, and the thickness of the silicon dioxide film is 0.1 to 5 µm, preferably 0.1 to 3 µm, more preferably 0.1 to 1 µm. |
