Abstract
A combined rotary printing press comprises an offset printer and a direct plate printer arranged in tandem. The offset printer comprises a transfer cylinder, a plurality of plate cylinders for applying an image to the transfer cylinder and an impression cylinder. The direct plate printer comprises a plate cylinder, inking means and a further impression cylinder. Paper handling means comprises a conveyor drum for feeding paper to the transfer cylinder in proper registration and means for conveying paper from the transfer cylinder of the offset printer to the impression cylinder of the direct plate printer. The impression cylinders of the offset printer and the direct plate printer are adjustable independently of one another and independently of the paper handling means so that each can be independently adjusted to provide the pressure desired without disturbing the paper registration.
