Abstract: A method of determining dampening-medium feed in an offset printing machine includes inking a printing plate of the printing machine so that tinting of areas of the printing plate which are normally ink-free during a production-run process occurs, and feeding a defined quantity of dampening medium and increasing dampening-medium feed, respectively, while detecting a process of ink taking from the tinted areas, which is applicable as a measurement for the dampening-medium feed being adjusted; and a device for performing the method.

Abstract: Combined dampening-inking unit for offset printing units having inking rollers engageable with a plate cylinder and including, as viewed in rotational direction of the plate cylinder, a first inking roller mounted so as to be adjustable independently of at least another next succeeding inking roller disposed in the rotational direction of the plate cylinder, and a dampening-medium distributor roller of a dampening unit cooperatively engageable with the first inking roller, including an oleophilic intermediate roller connecting the first and the next succeeding inking rollers to one another, an ink distributor roller engaging the next succeeding inking roller, the first inking roller being mounted so as to be swivelable about the dampening-medium distributor roller and liftable therefrom, and control means for selectively engaging the first inking roller with the plate cylinder, the intermediate roller and the dampening-medium distributor roller and for selectively disengaging the first inking roller therefrom
