ABSTRACT:
Tension of a web in a rotary printing press is regulated. The web passes through at least two printing groups in the printing press. A change in the extension of the web during the print run is determined based on a phase shift between a first phase position of a printing group and a second phase positioned measured after a last printing group. The change in phase position is compensated for by a change in the web tension prior to the first printing group.
