Title: Setting up ink distribution profiles in printing machines
Inventor: LOFFLER GERHARD
IPC: B41F31/00
Filed: 1988-03-08
Abstract: For each print job, an ink distribution profile is created by zonewise adjustment of the ink metering means at the ink fountain, said adjustment corresponding to the ink quantity required for the respective printing product. When resetting the inking unit from the preceding print job to a new print job, the existing ink profile is reduced to a stage that the new ink profile for the subsequent print job can be built up shortly afterwards without having to empty the inking unit completely and without having to clean it. Two alternatives are proposed; in the first, the intermediate stage comprises a profile- independent uniform thin basic ink layer on the inking rollers; in the second, differences between preceding and new print jobs are computed and a suitable equilibrium state set up as the intermediate stage.
