Abstract

Method of regulating an amount of dampening medium on a printing plate of an offset printing machine, includes determining the amount of dampening medium on the printing plate, adjusting the rotational speed of a dampening ductor and/or the like to a given set value so as to regulate the amount of dampening medium on the printing plate and, for regulation deviations wherein the set value is greater than an actual value, driving a controller with a greater amplification factor than for regulation deviations wherein the set value is smaller than the actual value.
