ABSTRACT:
A layer of ink containing a light absorbing heat generating substance is provided on the rear surface of a heat-sensitive plastic film of a thermal stencil sheet when the heat-sensitive plastic film is perforated by a laser beam. When a rotary stencil printer is used, a stencil sheet is mounted around a printing drum of the rotary stencil printer in a condition adhesively held by an ink layer, then a laser beam is irradiated to a portion of the stencil sheet to be perforated, and then the printing process is carried out with the stencil sheet as it has been mounted around the printing drum for the perforation.
