THERMOSENSITIVE STENCIL PRINTING PLATE, ITS PRODUCTION METHOD AND APPARATUS, AND STENCIL PRINTING MACHINE

摘要

The present invention provides a plate material made only of thermoplastic resin film by use of a polyester film so that an ink-penetrating opening can be thermally perforated without increasing the output of a thermal head. The film is a heat sensitive stencil plate material 12 for stencil printing having a predetermined thickness, and is composed of an extended PET film or a extended low melting temperature film produced by copolymerizing PET and PBT. Many minute recesses 14 are formed on one side of the film by templating. The templating can be carried out at a working pressure of 10<4>x10<2(m-t)/(m-g) >Pa or more, when the working temperature is t° C.; the melting point of the film is m(° C.) and the glass transition point of the film is g(° C.).
