Abstract
A method of producing a planar stamp including a stamp member, an ink reservoir, and a stamp frame. In the method, after fitting the ink reservoir into the stamp frame, the stamp member, without a print surface and made of a polyethylene foam sheet, is adhered to the stamp frame in order to enclose it in the stamp frame, whereby a planar stamp portion is assembled. Then, a thermal head of a print surface forming apparatus is moved along an entire surface of the stamp member, while the thermal head is in contact with the stamp member, in order to form a print surface. Lastly, ink is injected into the ink reservoir in order to impregnate the stamp member with the ink.
Claims7
A method of producing a penetration print type planar stamp including a stamp member with a print surface, an ink reservoir for holding ink, and a stamp frame for holding the stamp member and the ink reservoir, said method comprising the steps of:
- assembling a planar stamp portion, after fitting the ink reservoir into the stamp frame, by adhering the stamp member without the print surface to the stamp frame for enclosing said stamp member in said stamp frame, the stamp member being a thermoplastic resin foam member having continuous holes;
- forming the print surface by moving a thermal head of a print surface forming apparatus along an entire surface of the stamp member, while the thermal head is in contact with the stamp member;
- and
- injecting ink into the ink reservoir to impregnate the stamp member with the ink.
