ABSTRACT:
A printing press has a replaceable cassette removably mounted on a frame. An impression cylinder cooperates with a printing cylinder in the cassette to define a nip through which sheet material moves during printing on the sheet material. The impression cylinder is movable relative to the frame between a retracted position in which the impression cylinder is offset to one side of the cassette and a printing position in which the impression cylinder extends into the cassette. In addition, a manually actuatable mechanism is provided to simultaneously adjust the size of opposite ends of a gap at the nip between the printing cylinder and the impression cylinder.
