A printing plate locking device is designed to facilitate clamping a printing plate to and from a plate cylinder in a rotary press without using any external tools. The printing plate device includes a printing plate tensioning device, arranged in the plate cylinder, which can be engaged with one end of the printing plate to tension the printing plate. The printing plate locking device also includes a lever which is operatively connected to the tensioning device; and a retaining device for holding the lever in a holding position when the tensioning device puts tension on the printing plate. A method of clamping the printing plate utilizes the printing plate locking device structure.

In a multicolor printing press which has a plurality of printing sections arranged in vertical alignment, the multicolor printing press facilitates adjustment of register position between a plurality of printing sections. The multicolor printing press thus has a first printing section which includes at least one first plate cylinder, and at least one second printing section which includes at least one second plate cylinder. The multicolor printing press is also provided with means for rotatably supporting the first plate cylinder in a fixed register position for providing reference position in adjustment of register position in the second printing section, means for rotatably supporting the second plate cylinder, and adjusting means of register position of said second plate cylinder relative to the reference position defined by the first plate cylinder.
