PLATE MAKING DEVICE, THERMAL STENCIL PRINTING MASTER, METHOD FOR ADJUSTING PRINTING DENSITY IN STENCIL PRINTING, AND STENCIL PRINTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To adjust a printing density by simple constitution without adjusting press contact force between a thermal stencil printing master and printing paper or the conveyance speed of the printing paper passing through a printing pressure part and to easily at a low cost correspond even in watermark printing, etc.;SOLUTION: A laminate in which a porous resin film is laminated on a thermoplastic resin film is used as the thermal stencil printing master 61. The porous resin film is crushed by a press means 20 comprising an upper part press roller 21 and a lower part press roller 22 to lower ink permeability to adjust the printing density. The quantity of crushing is adjusted by a press force adjusting mechanism 23. The crushed thermal stencil printing master 61 is punched by a thermal head 91 while being conveyed by a platen roller 92.;COPYRIGHT: (C)2003,JPO
