Abstract: A printing plate made only of a thermoplastic resin film is provided by use of a polyester film so that an ink−penetrating opening may be thermally made in the film without increasing the output of a thermal head. The film is a thermosensitive stencil printing plate (12) composed of an oriented PET film or a low−melting film produced by copolymerizing an oriented PET and PBT and having a predetermined thickness. A multitude of small recesses (14) are made in one side of the plate (12) by embossing. The embossing pressure P can be 10 4 × 10 2(m−t)/(m−g) Pa where t (°C) is the embossing temperature, m (°C) is the melting point of the film, and g (°C) is the glass transition point of the film.

Abstract: A plate making method for mimeographic printing which melts by thermal head heating a plate consisting of a thermoplastic resin film to form ink permeable openings. A film (12) is formed on one surface thereof with many fine recesses (14). A heater size for a thermal head (10) satisfies the relations, HM > 0.6PM and HS > 0.7PS, when the main−scanning−side array pitch of the heater is PM, main−scanning−side heater length HM, sub−scanning−side feed pitch PS, and sub−scanning−side heater length HS. A surface opposite to the fine recess−formed surface of the film is heated by an energy output of up to 35 milli−joule per mm 2 . The heated portion is melted for communication with fine recesses to form ink permeable openings. Ink−permeable openings can be thermally punched independently in the film without increasing a thermal head output, and plate making is realized by using a plate consisting of only a thermoplastic resin film.
