A printing press is comprised of at least one printing cylinder. A
displaceable inking unit and a displaceable plate changing device can
alternatingly be placed against the printing cylinder or can be moved out
of contact with it. The inking unit and the plate changing device are
coupled together so that their respective displacements are accomplished
by a common drive. The two move in opposite directions with respect to
the printing cylinder and may be connected together. Alternatively, each
may have its own drive, with the two drives being coupled together by a
common controller.
