Abstract:
1. A multipass printing method for printing a substrate by depositing printing ink thereon, the method comprising the steps of: a) incrementally advancing a substrate to predetermined printing positions disposed along a path of travel; b) at each printing position, passing a print head having a predetermined nozzle length L c) during a pass, actuating a nozzle to deposit printing ink on a predetermined number Q of selected print locations on the given scan line addressed by that nozzle on that pass; and d) repeating steps a) through c) P the method being characterized in that, on any given pass, the number Q of selected print locations onto which printing ink is deposited by each of the N nozzles varies from nozzle to nozzle along substantially the entire length L wherein the weighted smoothing spline function is a polynomial B-spline function of the order “j”, where j=(P
