Abstract

Assembly for influencing inking in printing machines including a color density measuring device, a device for comparing nominal values and actual measured values, at least one electronic computer for linking the measured values with adjustment values, devices for metering ink feed zonewise to a printing plate and having ink metering elements with appertaining adjustment members and feed-back or reply devices, including a plurality of displays assigned to the ink metering elements for representing adjustment values of all ink zone adjustment members, respectively, of a printing unit, said displays providing exact recommendations to an operator of the assembly, before adjustment of the inking zone adjustment members, for adjusting the adjustment members to predetermined positioning nominal values and signaling to the operator absolute adjustment travel thereof both in magnitude and direction and a positioning device having means selective by the operator for following up the ink zone adjustment members individually and of at least one printing unit, respectively, the positioning device being coupled with the displays.
