ABSTRACT:
A printing apparatus has a printing cylinder rotatably supported by a main frame. A subassembly contains a plurality of anilox rolls rotatable about parallel spaced-apart axis with the subassembly being rotatable about an axis parallel to and between these spaced-apart axes. A locking arrangement secures the subassembly in selected positions whereby any selected one of the anilox rolls can be brought into an operative position for cooperating with the printing cylinder for printing. Alternative ink systems supply ink to the selected anilox roll when in the operative position. Preferably the subassembly is supported at its ends by gear casings which are adjustably rotatably mounted in a subframe which itself is pivotally mounted in the main frame. The ink rolls may be anilox rolls with different surface screens.
