Abstract
In a stencil printing method, an image on a printing material is formed by forcing ink to pass through perforations formed in a stencil sheet and to transfer onto the printing material. The method includes preparing ink transfer device having a surface made of an elastically deformable material; applying ink on the surface of the ink transfer device; and pressing the surface of the ink transfer device against the stencil sheet. Thus, a part of the ink transfer device having the ink deforms to enter into the perforations, thereby transferring the ink onto the printing material through the perforations of the stencil sheet to conduct printing on the printing material.
