Abstract
The circumferential register of a web passing through printing units of a web-fed rotary press is accomplished by determining an actual value of the tension in the web. An angular position or an angular velocity of a cylinder of a first print unit, with respect to a cylinder of a second print unit, is varied based on this determined tension. This corrects any register offset without the need to control web tension and without the use of an optical recognition system. The value of the needed change for the cylinder angular position or velocity is determined as a function of the measured tension of the web.
