A method for controlling cut-off registration in a printing press having printed webs includes applying print control marks which are invisible to the human eye to the printed webs; passing the webs pass through cut-off register control actuators; assembling the webs into a bundle for cut-off; scanning the webs with sensors to determine the actual positions of the marks; comparing the actual positions with desired positions of the marks; and generating signals for the cut-off register control actuators based on the comparison.

Method for cut-off register control

An ink regulating device that measures color in a web-fed rotary printing machine for printing a printing material web or sheets in a plurality of colors. The ink regulating device measures and evaluates the colors black, cyan, magenta, and yellow, and after general calibration (i.e., the recording of standard values), derives set values for the inking zone setting devices, without requiring any further patterns, and without the need for a special copy when the printing pattern is changed.
