Abstract
In accordance with an embodiment of the invention, a method of aligning multiple staggered pens in a printer includes printing a series of test block patterns, the test block patterns containing a plurality of composite references printed with a set of pens from at least two rows of a pen arrangement of the printer and a plurality of alignment blocks. The method further includes measuring relative distances between the plurality of composite references and the plurality of alignment blocks to determine a per-pen misalignment and modifying pen operation to compensate for the per pen misalignment.
