摘要： A printing machine has at least one machine element which can be adjusted by the use of a setting element. An adjustment of the one machine element has an effect on the quality of the printing performed by the printing machine. An optical detection device, which includes a sensor that is oriented toward the surface of a material which is being printed, detects the quality of the printing. A controlling device receives data from the optical sensor and adjusts, together with the setting element, the at least one machine element based on a difference between a quality of the printing which has been specified as a set value and the quality of the printing detected as an actual value by the optical detection device. This adjustment is done to manage the differences between the set value and the actual value. The control is based on the fact that the quality of the printing is detected in its entirety by the optical detection device and the data is evaluated with regard to disturbing influences acting upon the quality of the printing.

摘要： At least one register and an ink density are controlled in a printing machine having at least one printing unit which includes a forme cylinder, a transfer cylinder, and a counter-pressure cylinder. An image sensor records an image from a print substrate, which is imprinted with ink, inside the printing unit, and sends data correlated to that image to an evaluation unit. The data for the last printed image is compared with prior data and in response, the evaluation unit generates a command that is directed to an actuator for controlling the supply of ink. The image sensor is oriented towards the print substrate and detects the entire width of the printed substrate, which width is transverse to a direction of substrate conveyance. The evaluation unit generates the actuating command to control the supply of ink based on data from the image sensor and taken over the entire width of the substrate. The evaluation unit also controls register, based on this data. The forme cylinder has a separate drive which can be controlled separately or that can be regulated by the counter-pressure cylinder assigned to it.
