ABSTRACT OF THE DISCLOSURE This invention relates to a printing press comprising at least one printing stand, in which an impression cylinder, two printing cylinders, which are movable into engagement with the impression cylinder, and inking rollers associated with said plate cylinders, are rotatably mounted, and a main drive, which is operatively connected to the impression cylinder, wherein the impression cylinder, the plate cylinders and the inking rollers comprise stub shafts, to which gears are secured, which are adapted to be in mesh for synchronous rotation during a printing operation. In order to accomplish the object to provide such a printing press in which a loss of production in case of a change-over from one printing job to another can almost entirely be avoided the invention resides in that each plate cylinder is operatively connected to the main drive for the associated impression cylinder by a clutch for uncoupling the plate cylinder from said main drive and is operatively connected to a controllable servomotor for accelerating the plate cylinder to rotate at the same peripheral velocity as the impression cylinder (synchronous velocity), and each plate cylinder when it has been accelerated to the synchronous velocity is adapted to be coupled to the main drive for the impression cylinder.
