ABSTRACT:
A dampening apparatus for a lithographic press in which a train of rollers conducts dampening fluid from a pan to the form roller or applicator roller of the press that is in contact with the printing plate. The fluid is conducted from a pan roller to a metering roller and then to a transfer roller which is in rolling engagement with and rotating at the same peripheral speed as the form roller. Variation in the amount of dampening fluid which is transferred to the form roller is achieved by driving the pan roller and intermediate roller directly from a separate source of power and permitting the remaining rollers of the train to be driven from the printing plate or inking rollers. By varying the speed of rotation of the pan roller and intermediate roller the amount of fluid transferred to the form roller may be varied to the end that the exact amount of water required by the form roller may be provided.
