Abstract
The method effects a closed-loop control of the quantity of dampening solution during printing. The metering of the quantity of dampening solution to be applied to the printing material is preferably a function of the printing speed. In addition, at least one of the variables that influence the requisite quantity of dampening solution in the printing process is taken into account.
Claims5
A method for the closed-loop control of a quantity of dampening solution in a printing process, which comprises:
- metering a quantity of dampening solution to be applied to a printing material in the printing process and adjusting the quantity in dependence on a first variable;
- in addition to the first variable, taking into account at least one further variable influencing the requisite quantity of dampening solution in the printing process in the form of a set-point change ΔW as an input parameter for a dampening-solution controller.
