ABSTRACT:
A dampening system for a printing press uses a dampening fluid spray system to apply dampening fluid to a first of several serially arranged transfer rollers. The dampening fluid is carried by these transfer rollers to a dampening forme roller and then to a plate cylinder. The surfaces of the dampening forme roller and the several transfer rollers after the first such transfer roller are oleophilic. Spaced levers adjustably support several of the transfer rollers and the dampening forme roller.
