Abstract: A stencil printing method employs a stencil printing machine comprising: a drum which is rotatable and has a outer peripheral wall formed by an ink impermeable member and in which a stencil sheet is mounted on a surface of the outer peripheral wall; an ink supply device which has an ink supply unit provided on the outer peripheral wall of the drum and supplies ink on the surface of the outer peripheral wall from the ink supply unit; and a pressure roller which presses a fed print medium onto the outer peripheral wall; the method comprising: a step of mounting a stencil sheet on the drum; a step of plate-making the stencil sheet; and a step of transferring a water-based ink to a print medium by making the water-based ink pass through perforations of the stencil sheet.

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.

Abstract: A stencil printing machine includes a drum which is rotatable and has an outer peripheral wall formed by an ink impermeable member and in which a stencil sheet is mounted on a surface of the outer peripheral wall. An ink supply device has an ink supply unit at a printing position upstream of a maximum printing area of the outer peripheral wall of the drum and supplies ink on the surface of the outer peripheral wall from the ink supply unit. A pressure roller presses a fed print medium onto the outer peripheral wall.
