ABSTRACT:
A printing apparatus for printing a printing-paper is provided with two plate cylinders each holding a plate, two blanket cylinders coming into contact with the plate cylinders respectively and a single impression cylinder coming into contact with these blanket cylinders. Each plate has two printing areas. The two plate cylinders and the two blanket cylinders have the same diameter, which is twice that of the impression cylinder. The impression cylinder is in contact with a feed cylinder and a removal cylinder, and a reverse cylinder is provided to be in contact with the feed cylinder and the removal cylinder. The printing apparatus performs printing corresponding to one of the printing areas of each plate on a single surface of the printing-paper, reverses the printing-paper, and performs printing corresponding to the remaining printing area of each plate on another surface of the printing-paper. Thus, the printing apparatus can execute two-color printing on both surfaces without exchanging inks, despite its compactness.
