Abstract (en)
[origin: EP0522301A1] A method for monitoring and controlling the printing process, especially in offset printing machines is proposed, in which increases in tonal value, for example, are not to be evened out solely by varying the inking. The method according to the invention is divided into a learning phase and an ability phase. The quality characteristics which can be recorded by measurement on the printing product form a characteristics space in which association vectors from process-related evaluations of trial prints are assigned to certain categories and/or causes of interferences (learning phase). In the ability phase, that is to say the control and monitoring of the printing process, on the basis of the association with the category and/or the cause of the interference determined, said category is displayed and/or interventions are made in the process via the cause determined in this manner with the aim of eliminating said cause. <IMAGE>
