STENCIL PRINTING METHOD

WIPO Patent Application WO/2007/032477

A1

A stencil printing method which uses a stencil printing device comprising a drum that is free to rotate and mounted on the surface of the outer peripheral wall thereof with mimeograph paper, an ink supplying means having an ink supply unit positioned on the printing-upstream side of the maximum printing area of the drum's outer peripheral wall to supply ink onto the surface of the outer peripheral wall from this ink supply unit, and a press roll pressing a fed printing medium against the outer peripheral wall, and which transfers onto the printing medium ink that has passed through the perforated portions in plate-made mimeograph paper by pressing with the press roll while rotating the drum mounted with the plate-made mimeograph paper, wherein printing is carried out so that the relation between a pressing pressure (A:N) by the press roll, the peripheral speed (B:m/s) of the drum, ink viscosity (C:mPa·s) and the thickness (D:μm) of the mimeograph paper satisfies the following expression (1). (Expression 1) 130≤√(B/A)×(C+200)×√D≤400 (1)
