ABSTRACT:
On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length. A process for preparing a stamp of the present invention comprises simple steps, and therefore the high-quality stamp can be promptly provided.
