ABSTRACT:
There is provided a printing press that can guide a printing plate, which is held in clamped relationship with the clamping gripper, so as to be mounted on the plate cylinder with accuracy, while guiding a printing plate in the plate discharge direction with accuracy, as well as preventing deterioration of the reliability for a long time. A printing plate guide plate having a leading end provided with guide rollers and guide blocks guides a printing plate when it is supplied to a plate cylinder and discharged therefrom. A pivotally moving plate auxiliarily guides the printing plate when it is guided by the printing plate guide plate. A link mechanism links the printing plate guide plate with the pivotally moving plate so as to switch guide members for guiding the printing plate by the contact from guide rollers to guide blocks or vice versa, so that when the printing plate guide plate is held at a plate supply position, the guide rollers contact the printing plate at a first guide position, and when the printing plate guide plate is held at a plate discharge position, the guide blocks contact the printing plate at a second guide position.
