Abstract

An inking unit for printing presses, preferably offset printing presses, can have a plurality of plate-inking rollers for inking a plate cylinder along with a multiplicity of inking rollers. The inking rollers can be positioned to supply ink flow, in at least two directions to the plate-inking rollers. The inking rollers and the plate-inking rollers can then form a closed chain of rollers, and can enclose a space therebetween. A measuring device can be provided to monitor the temperature of the air within this space, with measured values being used for control of the temperature of the inking unit.
