A seal carving apparatus includes a thermal head having a plurality of heat generating elements disposed in lines, and thermal drive control means that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means controls a pulse time width for thermally driving the individual heat generating elements of the thermal head under pulse width modulation control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.

A cosmetic stamp includes one or more stamping elements, a stamp compartment or housing for carrying the one or more stamping elements and a stamping substance. For example, a cosmetic stamp is an eyebrow stamp that is used for the application of a cosmetic eyebrow using the one or more stamping elements and the stamping substance. A method of applying a cosmetic stamp includes removing a stamping element from a stamp compartment, opening a lid of the stamp compartment, and pressing the face of the stamp to a stamping substance.

The invention provides a porous stamp material for laser processing that is available for continuous extrusion molding. A material including at least 100 parts by weight of thermoplastic resin, 50-250 parts by weight of hydroxylated compound whose dehydration starting temperature is 100 to 500° C., and water-soluble pore-forming material that has 10-60 μm average particle diameter is mixed to obtain a mixed material. The obtained mixed material is extruded to obtain an extrusion molded product. The obtained extrusion molded product is processed with an aqueous solvent to elute the water-soluble pore-forming material, thereby yielding a porous stamp material that has continuous pores having 10-60 μm pore diameter. The obtained porous stamp material is laser-processed to manufacture a stamp.

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.
