Claims

[Scope of Utility Model Registration Claim] An ink supply mechanism that kneads and applies ink supplied from an inkwell to a plate on a plate cylinder, and a process that involves applying ink to the entire surface of the plate before applying ink to the plate by this ink supply mechanism. In an offset printing machine equipped with a dampening water supply device that supplies dampening water to the printer, the offset printing machine is provided separately from the dampening water supply device, and
a cleaning mechanism comprising a cleaning roller facing the vibrating roller that contacts the inking roller in the ink supply mechanism, and a supply section and a recovery section for supplying cleaning liquid to the cleaning roller; upon completion of printing by the plate on the plate cylinder; a water supply drive unit that causes a water transfer roller to face an auxiliary vibrating roller that is in contact with an inking roller of the ink supply mechanism in the dampening water supply device in a position that allows setting a maximum water supply amount; An offset printing machine comprising means for sequentially controlling the position of a water transfer roller of a driving section and the operation of a cleaning liquid supply section and a recovery section in the cleaning mechanism.
