Multi-color printing apparatus

Abstract

In each of the pressure transferring sections of the printing device, a pair of cylinders, a screen positioned to pass over the cylinders and an inking device for supplying ink to the original printing stencil on the screen are arranged. An original printing stencil supplying device and a used printing stencil collecting device are moved as an integral unit to the first pressure transferring section by means of a moving device. Then, the used printing stencil on the screen is collected by the used printing stencil collecting device and a new engraved original printing stencil is supplied from the original printing stencil supplying device and mounted on the screen. Ink for the first color is supplied to the original printing stencil by means of the inking device. Then, the original printing stencil supplying device and used printing stencil collecting device are moved to the second pressure transferring section, and the process is repeated. In this way, the original printing stencils having different images for respective colors are mounted on all the pressure transferring sections, and one sheet of printing paper is passed through the pressure transferring sections so that the images of the respective colors are printed on the printing paper.
