Abstract
In a stencil printing apparatus capable of duplex printing, in which a front surface printing process for printing a front surface image on one surface of a sheet of paper fed by a sheet feeding unit is performed, the sheet is re-fed to a sheet re-feeder, and then a rear surface printing process for printing a rear surface image on the other surface is performed. The positions of the front surface image and rear surface image to be formed on the sheet can be moved together by a predetermined amount in a single direction side of a sheet conveyance direction.

A stencil printing apparatus capable of performing duplex printing, in which a front surface printing process for printing a front surface image on one surface of a sheet is performed, said sheet is re-fed, and then a rear surface printing process for printing a rear surface image on the other surface of said sheet is performed, comprising:
- a printing unit including a printing cylinder and a pressing device provided to be free to contact and separate from said printing cylinder;
- a sheet feeding unit for feeding said sheet toward said printing unit;
- a sheet re-feeder that temporarily accommodates said sheet after a printed image is formed on said front surface thereof in said printing unit, and that then re-feeds said sheet toward said printing unit;
- and
- a controller configured to control at least the printing unit and the sheet feeding unit to set a position of said front surface image and a position of said rear surface image to be formed on said sheet to be moved together by a predetermined amount in an identical direction side of a sheet conveyance direction based on a single selection of an image position adjustment setting by a user.
