Abstract
A color plane registration error method and system include printing a plurality of predetermined patterns of dots, each predetermined pattern having the respective dots arranged symmetrically around a common center of gravity. The center of gravity of each of the printed patterns and the distances between centers of gravity of respective patterns are determined to measure the color plane registration error.
