  • Stencil printing machine
    Patent number: 7117786
    Abstract: A stencil printing machine has a rotatable printing drum including an outer peripheral wall of ink impermeable material. A stencil paper is mounted on the surface of the outer peripheral wall. An ink supplying mechanism includes an ink supplying unit in the outer peripheral wall of the printing drum and supplies ink to the surface of the outer peripheral wall. A pressure roller presses a fed print sheet against the outer peripheral wall. When an initial printing operation is performed after a stencil paper is mounted on the printing drum, the ink supplying mechanism is caused to supply the surface of the outer peripheral wall, in advance, with an amount of ink which is larger than an amount of ink which is supplied for second and proceeding printing operations.
