Abstract:
A stencil making apparatus for perforating stencil sheet having supporters in a mesh structure having a regular pitch, said stencil making apparatus comprising:a thermal print head having a plurality of heat generating members arranged at a regular pitch; setting means for setting a value of N, which is equal to or larger than 2, such that a regularity is diminished in a relationship between a pitch of the supporters of the stencil sheet and a pitch of the heat generating members of the thermal print head; and controlling means electrically connected to the thermal print head and the setting means for dividing inputted image data of one line of main scanning into N lines based on the value of N set by the setting means such that contiguous N heat generating elements of the thermal print head generate different lines of print data divided into 1/N in the one line and outputting the N lines of the print data to the thermal print head at different timings.
