PURPOSE:To enable the heat of a thermal head to be favorably transmitted to a resin film, by a method wherein a screen regularly woven from fibers having a diameter of not larger than 30mum is used as a base paper, in a stencil comprising a resin film adhered to a base paper. CONSTITUTION:A stencil is formed by adhering a heat-shrinkable resin film 13 of polyethylene terephthalate or the like to one side of a screen 12 regularly woven at 100 mesh from fibers 11 having a diameter of about 30mum. To thermally cut out characters or patterns in the resin film 13 of the stencil, the resin film 13 is pressed against a thermal head, and the stencil is moved while heating. In this case, since the diameter of the fibers 11 constituting the screen 12 is about 30mum, it is sufficiently smaller than the length of one unit of heating resistors provided in the thermal head in a density of 12 dots/mm., and the heat generated at the heating resistors is effectively transmitted to the resin film 13, whereby the holes are favorably formed. |
