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.
