ABSTRACT:
In a rotary press wherein ink nozzles apply different colored inks to different sections of an inking cylinder along the length thereof, and wherein excess inks run off of the inking cylinder into a compartmented inking pan, an anilox cylinder, by which ink is transferred from the inking cylinder to a plate cylinder, rotates on an axis that is fixed relative to a stationary frame for the press. The ink pan and its dividers are also stationarily secured to said frame. The plate cylinder and an impression cylinder that cooperates with it for imprinting a web are rotatably supported on sliders that carry those cylinders for bodily motion towards and from the anilox cylinder and one another. For easy change of ink color on inking cylinder sections, each compartment of the ink pan has plural readily closeable drain outlets that respectively lead to different ink reservoirs, there is an ink pump for each reservoir, and an elongated ink feed manifold for each pump has readily closeable outlets that provide for disconnectable communication with any ink nozzle.
