ABSTRACT:
A plate-making apparatus for stencil printing includes a plate feed section which feeds the heat-sensitive stencil plate that is an extended thermoplastic resin film with a predetermined thickness, and a heater to form ink-permeable openings in the film by heating the film, in which an opposite side surface to the minute recess side of the film is heated by the heater, the heater is a thermal head, a tensile stress at the time of extension internally remains in said thermoplastic resin film, an energy output of the thermal head for heating sufficiently satisfies to fuse-penetrate a thin closing portion of the minute recess, but it is restricted to the range which does not fuse-perforate a thick portion except the recess portion of the film, so that the openings are formed by the heated fused portion communicating the minute recess.
