ABSTRACT:
A photosensitive printing member comprises a porous supporting member and a photosensitive layer formed on the porous supporting member. The photosensitive layer comprises a photosensitive material and a foaming material or filler melted or dispersed in the photosensitive material. A porous stamp plate can be formed with fewer process steps than the conventional method and without using a mold. As a result, a small number of photosensitive printing members can be used to produce various models of stamps.
