Abstract
A method for reducing tension fluctuations in a web while printing multiple copies of a print job on the web comprises providing a printing system with a print station one or more rollers adapted to receive tension control commands. The tension control commands operate on the rollers to control the amount of tension in the web. The printing system is used to print a first copy of the print job. Tension changes produced during the printing of the first copy of the print job are measured. First tension control adjustments based on the measured tension changes are used to adjust the tension control commands to the rollers in the printing system for printing a second copy of the print job, thereby reducing tension fluctuations.
