ABSTRACT:
An offset printing press comprises a plate cylinder onto which a printing plate is attached, a form dampening roller having an elasticity on its outer surface, a water fountain roller immersed into water in a water pan, and intermediate roller means for transferring the water from the water fountain roller to the form dampening roller. The intermediate roller means comprises a water oscillating roller which has a hydrophilic property on its outer surface and is capable of reciprocating in its axial direction with contacting the form dampening roller. Also, the offset printing press comprises first moving means for moving the form dampening roller close to and away from the plate cylinder; and second moving means for moving at least one of the water oscillating roller and the form dampening roller so that these two rollers can be moved close to and away from each other.
