Abstract: A printing system includes a first imaging unit configured to print a first image and a registration mark associated with the first image on a web 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 web based on the registration mark and to instruct the second imaging unit to print the second image on the web. The second image is shifted in its entirety in accordance with the calculated offset and is printed on the same side of the web as the first image.

Abstract: 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.

Abstract: A method of detecting an alignment error includes the steps of controlling a first portion of one or more imaging units to image on a substrate a first plurality of substantially parallel lines extending along a first direction and a second plurality of substantially parallel lines extending along a second direction and controlling a second portion of one or more imaging units to image a third plurality of substantially parallel lines extending along the first direction and a fourth plurality of substantially parallel lines extending along the second direction. One or more distances between adjacent lines of the second plurality of lines are varied and one or more distances between adjacent lines of the fourth plurality of lines are varied. Further, the lines imaged by the first and second portions form an alignment pattern.

Abstract: A method of printing on a substrate includes the steps of instructing a first imaging unit to print a first image and a registration mark on a substrate contemporaneously during a production run and detecting the registration mark. The method further includes the steps of determining a position on the substrate where a second image is to be printed in accordance with the detection of the registration mark and instructing a second imaging unit to print the second image on the substrate in accordance with the determined position.
