Abstract
Methods and devices print markings on an item in a first printing pass, using intended locations for the markings, to produce initial printed marks. Such methods and devices further scan the item after the first printing pass to detect actual printed locations of the initial printed marks. These methods and devices also compare the actual printed locations to the intended locations to identify the printing registration variation. Thus, such methods and devices change the intended locations for the markings based on the printing registration variation to generate corrected locations for the markings; and then reprint the markings directly on the initial printed marks a second time on the item in a second printing pass using the corrected locations for the markings, using the marking device.
