Porous resin stamp producing method, involves selectively irradiating light through original on porous resin block surface, which contains phthalocyanine pigment as heating material, and forming ink exuding portions

摘要

An original through which light is capable of passing is put together with a porous resin block combined with phthalocyanine pigment which generates heat by light irradiated from a light source towards the surface of porous resin block. An ink exuding portion is formed by melting a surface layer of resin block by the heat generated by phthalocyanine pigment.
