ABSTRACT:
An offset short inking unit includes a screen surface ink fountain roller that is supplied with ink and that transfers the ink to one or more printing plates. Dampening fluid is also supplied to the printing plates from a dampening unit. One or more dampening fluid separation units are placed in contact with the surface of the screened ink fountain roller and operate to remove any residual dampening fluid from the screen roller before this residual dampening fluid can find its way into the fresh ink supply in the ink fountain.
