ABSTRACT:
A stencil printing machine, which includes: a drum which is freely rotatable and has an outer peripheral wall formed of an ink impermeable member, in which a stencil sheet is mounted on a surface of the outer peripheral wall; an ink supplying device for supplying, to the surface of the outer peripheral wall, an ink guided from an ink tank; an ink recovery device for recovering, from an ink recovery portion, an extra ink on the surface of the outer peripheral wall; and a pressure roller which presses a print medium to the outer peripheral wall. The ink tank includes a main tank portion where unused ink is stored, and a sub-tank portion where the ink recovered by the ink recovery device is stored. The ink supplying device preferentially supplies the ink in the sub-tank portion.
