PURPOSE: To obtain an ink sheet supplying ink only to the perforated part of base paper, imparting no chance allowing a hand to touch ink at the handling time of the base paper and enabled in multicolor printing free from color mixing by one printing, by providing an ink impregnated perforated layer on the upper surface of a layout sheet and adhering a cover film to the layout sheet through said perforated layer.

CONSTITUTION: An ink impregnated perforated layer 2 is fixed to the upper surface of a layout sheet and a cover film 3 is superposed on said perforated layer 2 while the peripheral edge parts of the film 3 and the layout sheet 1 are adhered to hermetically close the ink impregnated perforated layer 2. Release paper 5 is adhered to the under surface of the layout sheet 7 through a sticking layer 4 and the ink sheet can be adhered to the plate cylinder of a rotary mimeographic machine through the sticking layer 4 by peeling off the release paper 5. When the ink sheet is superposed only to the perforated part of base paper to perform printing, excessive ink is not adhered to a non- perforated part and, therefore, a band is not contaminated. Multicolor printing free from color mixing is enabled by one printing.
