ABSTRACT:
Dampening solution is supplied to a printing form of an offset printing press. The quantity of dampening solution is alternatingly varied about a preselectable mean value between a minimum value and a maximum value. The variation is independent of possible fluctuations due to deviations in the controlled supply of dampening solution. The mean, minimum and maximum values are defined from an ink distribution on a printed subject.
