Abstract
A printing apparatus includes a first plate cylinder and a second plate cylinder. Each plate cylinder supports a plate mounted peripherally thereof having two image areas. Four ink feeders contact and feed inks to the image areas on the plate when mounted on the first and second plate cylinders. A first blanket cylinder has a diameter equal to a diameter of the first plate cylinder and is contactable therewith. A second blanket cylinder has a diameter equal to a diameter of the second plate cylinder and is contactable therewith. An impression cylinder having a diameter half the diameter of either the first and second plate cylinders as well as the first and second blanket cylinders, is contactable with the first and second blanket cylinders. A pair of grippers that each hold an end of the printing paper maintain two sheets of printing paper peripherally of the impression cylinder. A paper feed cylinder feeds the printing paper to the impression cylinder. A paper discharge cylinder discharges the printing paper from the impression cylinder after a required printing process. A gripper control mechanism controls the grippers to selectively carry out either one of a first opening and c…
