System and method for correcting stitch error in a staggered printhead assembly

摘要

An improved method of measuring relative positions of adjacent printheads in a printhead array has been developed. A pair of ink dashes is made with different colors of ink from adjacent printheads and an offset distance between the dashes is determined from color density measurements of the two dashes. The offset distance may then be used to adjust the stitch alignment of the two printheads.
