Abstract
Cross-track stitch errors in an inkjet printer are reduced by printing test patterns for a plurality of in-track offsets. A first test pattern portion to be printed with a first jetting modules includes a uniform density region having a slot with a slot width. A second test pattern portion to be printed with a second jetting modules includes a bar having a bar width, wherein the uniform density region of the first test pattern portion and the bar of the second test pattern portion overlap in the cross-track direction and are printed with jets in an overlap region between the jetting modules. The printed test patterns are analyzed to determine a stitch score that represents a degree of alignment between the slot in the first test pattern portion and the bar in the second test pattern portion. An aim offset value is determined where the slot and the bar are aligned.
