Abstract
A method for controlling an ink quantity in different zones of an ink roller in a printing machine, which includes prescribing nominal values of the ink quantity for each zone. A value of the ink quantity flow released for the zone by an ink source corresponds to each nominal value of the ink quantity. The nominal value for a given zone is changed from a first value to a second value, the ink quantity in the given zone is changed by prescribing a first correction ink quantity flow. The method further includes prescribing additional correction ink quantity flows for zones situated adjacent the given zone and, during a transition interval, setting the ink quantity flow for each of the zones situated adjacent the given zone to the sum of the correction ink quantity flow and the ink quantity flow corresponding to the nominal value of the given zone.
