ABSTRACT:
A damping unit for a printing press utilizes four rollers to provide damping medium from a source of the damping medium, to a printing plate cylinder. The various rollers in the damping unit are interrelated by appropriate diameter and circumferential speeds to effectively prevent the migration of printing ink back from the printing cylinder to the damping fluid source.
