Rotary offset duplex multi-colour printing machine - using pairs of cylinders separated by eccentrics according to type of printing being used

摘要

A strip of paper (1) is passed through a duster and static eliminator (3) for printing by two small cylinders (4,14) using the Orlof process on one side and offset on the other, or Orlof on both sides. Two larger cylinders (6,16) are provided for simultaneous offset-offset printing, and separated for the double Orlof process by eccentrics (7,17). - Each cylinder (e.g. 6) co-operates with four colour selectors (8) and inkers (9), and functions as a collector of four colours for transfer to a typographic plate carrier (5).
