ABSTRACT:
A perfecting sheet rotary offfset press has a top surface printing unit and a back surface printing unit each formed of an impression cylinder, and a blanket cylinder, a plate cylinder, and an inking mechanism which are disposed above or below the impression cylinder, respectively. The top and back surface printing units are connected through the impression cylinders constituting the respective printing units. A sheet is sequentially transferred by the respective impression cylinders of the top and back surface printing units, and printing is performed on the top and back surfaces of the sheet as it passes through the printing units. Thus, this perfecting sheet rotary offset press can print at high speeds and presents few printing faults, and its dimension can be made smaller.
