Abstract
A method and a device (1) for carrying out the method of optimizing dampening agent utilization in offset printing with a container (2) for dampening agent (3), a supply line (4) to at least one dampening mechanism, a recirculation line (5) for the unused dampening agent and a detector for measuring the fill level (10), which is functionally linked to the shutoff (7) for the supply (6). Servicing is reduced to a minimum, the cleaning intervals are lengthened, the utilization of dampening agent is improved, and the amount to be disposed of is reduced in that the detector for measuring the fill level (10) is set so that, after closing the shutoff (7), it reopens the supply (6) only when the fill level (11, 18) has been reduced so that after refilling the container (2) the contamination level is not increased compared to the instant prior to the interruption.
