Abstract

A method for controlling an inking unit of a printing press, includes resetting an ink metering element from first to second metered quantities for an intended inking level. The metering element is set to a temporary, third metered ink quantity by a control unit, for a time interval, during a non-steady phase of the inking unit before reaching the intended level. A value of a variable characterizing the inking state of printing material is determined and a plurality of sets of values for the variable are predefined, into which the determined value can be grouped. The temporary metering quantity is carried out: at a first rate and/or during a first time period if the value of the variable lies in a first set of values, and at a second rate and/or in a second time period if the value of the variable lies in a second, different set of values.
