Abstract:
In a thermal master making device including a thermal head having a plurality of heating elements arranged in an array in a main scanning direction, causing said thermal head to contact a stencil including a thermoplastic resin film, feeding said master at a preselected feed pitch in a subscanning direction perpendicular to the main scanning direction, and causing said plurality of heating elements to selectively heat to perforate said thermoplastic resin film in accordance with image data for thereby forming an image in said stencil in a form of a dot pattern, a pitch at which said plurality of heating elements are arranged and said feed pitch are substantially equal to each other, and said plurality of heating elements each have a length in the subscanning direction smaller than one-half of said feed pitch inclusive and have a length in the main scanning direction greater than said length in the subscanning direction.
