Use of a Sense Mark to Control a Printing System

A printing system includes a first imaging unit configured to print a first image and a single registration mark associated with the first image on a substrate contemporaneously during a production run, and a sensor configured to detect the registration mark at a point where the registration mark is within a second imaging unit. The printing system further includes a controller configured to calculate an offset along a width direction of the substrate based on the single registration mark and to instruct the second imaging unit to print the second image on the substrate. The second image is shifted in its entirety in accordance with the calculated offset and is printed on the same side of the substrate as the first image.
