An inking control system for a printing machine has an operating panel with operating and display elements for adjusting the zonally acting ink distribution devices in the printing machine. A spacing distribution along a given direction and a number of the operating and display elements corresponds to a spacing distribution and a number of the ink zones in the printing machine. A full size color monitor is integrated in the operating panel. The color monitor is enabled to display a full-size printed image on a scale of 1:1 and to spatially correlate the display of the printed image with the operating and display elements to directly visually associate the inking zones in the displayed printed image with the operating and display elements. One or more image recording devices in the printing machine record printed images while the printing material is conveyed through the printing machine. The acquired image data are forwarded to a computer that is connected to the ink distribution devices and to the one or more image recording devices. In the method, the display image for the screen is generated from a sequence of successive scans by the image recording device.

Operating panel for a printing machine, inking control system for a printing machine, and inking control method

A method for controlling the formation of an image on a printing form carrier for a printing machine, wherein image signals serving to generate a printing form are taken from a storage memory of a computer and fed to an imaging device, includes storing, in one region of the storage memory, image data for reproducing a subject to be evaluated after printing; storing, in another region, image data for reproducing a multiplicity of digital print control elements for use in printing machines in a printing plant; assigning a job for a selected printing machine and making a selection of image data for digital print control elements with which the job is optimally monitorable on the machine for performing the assigned job; and combining the image data for the selected print control elements with the image data for reproducing the subject in a further region in the storage memory, with the aid of the computer, to produce an image data set for forming an image on the printing form carrier.
