Abstract

A stencil is made by the use of a thermal head which has an array of resistance heater element arranged in a main scanning direction. The resistance heater elements are selectively driven while the stencil material is conveyed in a sub-scanning direction intersecting the main scanning direction so that perforations are formed in the stencil material in a predetermined size at a first pitch in the main scanning direction and a second pitch in the sub-scanning direction. The stencil material is perforated so that unperforated portions which continuously extend in one of the main scanning direction and the sub-scanning direction to separate perforations in the other of the main scanning direction and the sub-scanning direction are left in the stencil material.
