More Information
Summary:A method and system for reducing registration errors in a printing system are disclosed. A plurality of tension zones is defined in the printing system. Tension on the web in one tension zone is controlled independently of the tension on the web in the other tension zones. The printing system also includes at least one roller for each tension zone. The rollers receive tension control commands and control the amount of tension on the web in their respective tension zones. The printing system is used to print a first copy of the print job on the web and a plurality of registration errors is determined. Tension control adjustments are computed for each tension zone based on the registration errors. The tension control adjustments are used to adjust the tension control commands to the rollers to print a second copy of the print job, thereby reducing registration errors.
