Abstract (en)
[origin: CA2014950A1] The invention relates to a method for determining the delivery of a moistening agent to an offset printing machine. For subject-dependent moistening-agent adjustment, it is proposed that inking of the printing plate (6) be carried out with acquisition of ink (toning) from ink-free areas in the production-run process, and that a specific delivery of moistening agent, or an increase in the delivery of moistening agent, shall then take place, including the ink-reducing process of the toning areas, which is used as a criterion for the moistening-agent delivery to be adjusted. In addition to this, a device for moistening-agent delivery is provided.
