Abstract
A system for using tension control adjustments on a web to reduce registration errors while printing multiple copies of a print job on the web comprises a printing system with a print station disposed opposite a first side of the web and one or more rollers adapted to receive tension control commands, the tension control commands operating on the first rollers to control the amount of tension in the web. A sensor is used to determine a plurality of registration errors produced during the printing of the first copy of the print job. A processor is used to determine first tension control adjustments based on the plurality of registration errors and to use the adjustments to adjust the tension control commands to the rollers in the printing system to change the tension in the web when printing a second copy of the print job, thereby reducing registration errors.
