Abstract
A printer calibration system and method enables images to be properly aligned over a printable medium in printing systems that use (i) one or more non-ideally shaped image transfer elements and/or (ii) when the one or more image transfer elements behave eccentrically. The systems and methods greatly improve color plane registration and correct for repetitive alignment problems associated with image transfer elements. Non-circularity imperfections associated with image transfer elements are determined. Then the image transfer elements are moved at a non-constant angular velocity to compensate for the circular imperfections.
