Abstract
A printing assembly has a moving web of print receiving material. A print positioning system has a coarse coordinate system and a fine coordinate system. Registration features on the web are used by a print positioning system to form the coarse coordinate system. The coarse coordinate system is employed to predict the location of the most recent registration feature. The fine coordinate system is re-synchronized to begin measuring from the location of the predicted registration feature.
