Abstract
A method enables a printing system to register images printed by two printers accurately. The method includes operating at least one marking station in a first printer with reference to a low frequency component and a high frequency of a velocity measurement for a web in the first printer, printing fiducial marks on the web with a marking station in the first printer, detecting the fiducial marks with a fiducial mark sensor in a second printer, generating a velocity measurement for the web as the web moves along a web path in the second printer that corresponds with the detected fiducial marks, and operating at least one marking station in the second printer with reference to a low frequency component and a high frequency component of the velocity measurement of the web moving along a web path in the second printer.
