Abstract
A stencil printing machine includes an image reading section, an image processing section for processing to convert image data into perforating data which is used for perforating a stencil sheet, an image perforating section for perforating the stencil sheet in accordance with the perforating data, a printing section for applying ink to a print sheet by using the perforated stencil sheet, and a data holding section for holding perforating data in stencil making operation as re-perforating data. When the number of print sheets comes to a predetermined number, the re-perforating data held in the data holding section is used to re-perforate another stencil sheet to exchange with the previous stencil sheet. The printing is again performed.
