Abstract
A process for producing a self-inking stamp capable of stamping repeatedly by filling ink in a stamp material having a continuous porous structure, wherein the stamp material having a continuous porous structure is provided with an occlusion body having a continuous porous structure and being impregnated with two or more kinds of ink having different functions so as to infiltrate two or more kinds of ink into the stamp material. In the process, there is used an occlusion body having a physical barrier and/or an isolation part which suppresses or inhibits mingling of two or more kinds of ink having different functions, and a self-inking stamp produced by the process.
Claims13
A process for producing a self-inking stamp capable of stamping repeatedly, the process comprising:
- (i) providing a self-inking stamp comprising (a) a stamp material having a continuous porous structure and a stamping face and (b) an occlusion body having a continuous porous structure adjacent the side of the stamp material opposite the stamping face, the occlusion body having a physical barrier, an isolation part, or both which suppresses or inhibits mingling of two or more kinds of ink;
- and
- (ii) impregnating two or more kinds of ink into the occlusion body so as to infiltrate two or more kinds of ink into the stamp material, wherein the ink holding force of the occlusion body is less than that of the stamp material.
