Abstract
A stamp-face platemaking device transports a medium holder inserted into a plate insertion portion to a printing unit. The medium holder holds a stamp face material at a center portion of a plate-like member, and has a cutout portion in one side end portion thereof. An optical sensor detects the top end portion of the medium holder on a sensor scanning line in the inserting direction, and the cutout start point and the cutout end point of the cutout portion. The size of the stamp face material in the inserting direction and/or the size of the stamp face material in a direction perpendicular to the inserting direction are set based on the positions of two of the detected end portions. When the cutout end point is detected, platemaking with the stamp face material is started. The cutout portion can have a wedge-like shape or a U-shape, or can change its positions and/or sizes.
