METHOD AND APPARATUS FOR FORMING STAMP

摘要

PROBLEM TO BE SOLVED: To eliminate a release of a stencil base sheet from a stamp side even in the case of stamp printing on a coating sheet by forming dots disposed in a dot matrix constituted of a hole forming means for perforating the base sheet with not continued perforated dots of a specific number or above in one direction. SOLUTION: A CPU 111 of a control unit 110 for controlling the stamp forming apparatus for forming a thermosensitive stencil base sheet of a stamp decides which of a dot to be perforated and a dot of not to be perforated a dot disposed in a dot matrix constituted of a heater of a thermal head 90 is based on an input of a keyboard 52 or the like, and controls so that dots of thinned candidate dot selected from the matrix do not respectively become perforated dots. The CPU 111 also controls so that the four or above perforated dots do not continue in all vertical and lateral directions by first thinning and three or above dots do not continue in an oblique directions by third thinning.
