Abstract
An offset printing press having an operating lever mechanism which is capable of controlling sequential printing operations by manipulating a single operating lever. The offset printing press includes an inking roller system and a dampening roller system. The inking roller system is supported to a first pair of frames, while the dampening roller system is supported to a second pair of frames pivotable relative to the first pair of frames. The operation lever provides pivotal motion of the second pair of frames for selectively applying water to a plate cylinder from the dampening roller system. Further, rollers in the dampening roller system are movable toward and away from each other.
