Abstract
In a stencil printing machine, one surface of a stencil sheet with a perforated image is placed in contact with an upper surface of a printing material. Ink is provided on the other surface of the stencil sheet. Suction force is exerted on a bottom surface of the printing material, so that the ink is allowed to pass through the perforated image and then transfer to the upper surface of the printing material, thereby completing stencil printing.
