Abstract
A rotary offset printing press having a pair of carriage mounted interchangeable plate cylinders is disclosed. The carriage is slidably mounted to the press and reciprocates along a generally linear path. The pair of plate cylinders are rotatably mounted to the carriage, and each of the plate cylinders is selectively moveable into an operative position in contact with the blanket cylinder. Accordingly, while the press is operating using one of the plate cylinders, the other plate cylinder is idle, which permits the impression sleeve thereon to be removed and replaced without stopping the press. The plate cylinders, when in their respective operative positions, contact the blanket cylinder at the same point of tangency, thus simplifying registration.
