Abstract
A method for registering patterns on a web to provide independent scale control in both the lateral and longitudinal directions is provided. The method includes routing the web over a first roller; routing the web over a second roller and stabilizing the web; applying a pattern to the web using process hardware; measuring registration of the pattern and providing an error signal; controlling lateral position error using the error signal; controlling longitudinal position error using the error signal; controlling lateral scale error using the error signal; and controlling longitudinal scale error using the error signal. The method provides independent scale control in both the lateral and longitudinal directions. Independent scale control avoids non-linear distortions otherwise imposed by attempting to accomplish both corrections by stretching the web in both directions.
