ABSTRACT:
A dual purpose stencil-forming sheet is provided comprising an ink-pervious fibrous tissue base having an ink-impervious impregnant therethrough, which impregnant is relatively non-bleeding and contains a red pigment. In a composite where the stencil-forming sheet is in contact with a white or pastel underlying backing sheet, the striking of a key or pin onto the stencil-forming sheet through a black inked ribbon simultaneously cuts the stencil, leaves a black marking on the cut stencil and leaves a red marking on the white or pastel backing sheet.
