ABSTRACT:
To expand a U printing system having two plate-blanket printing couples first to form a Y system for 2/1 (or 1/2) printing and then, further, to a dual-U system for 2/2 printing, with minimum space requirement, the axes of rotation of the base blanket cylinders are spaced from a separating line (3) between two superposed, staggered printing systems by different distances. An expansion group having two expansion plate-cylinder blanket couples likewise has the axes of rotation of the expansion blanket cylinders at different spacing from the separating line. Thus, by merely shifting a vertically arranged single blanket cylinder, previously in engagement with a lower blanket cylinder to release engagement therewith and engage against an opposite, newly arranged blanket cylinder, a space-saving 2/2 printing station is obtained.
