Abstract
A stencil printing method of the present invention intentionally transfers a smaller amount of ink from an upstream print drum to a paper sheet than from a downstream print drum to the same paper sheet such that images printed on the paper sheet one above the other have the same density at the end of a printing cycle. The method obviates a density difference and the roll-up of a paper sheet ascribable to retransfer particular to a single pass, color printing system. A stencil printer for practicing the method is also disclosed.
