<p>A computerized method (301-313)for improving ink-jet print quality. A jittered print mode is instigated to scatter print errors (see FIG. 4A-4C) having a cyclic cause, viz., patterns of visibly noticeable artifacts or dot arrangements caused by mechanical misalignments and vibrations and electrical tolerance variations that are cyclic in nature. A jitter (303, 305, 307, 311) of ink droplet firing time (209-215) is intentionally introduced whereby printed dot placement is offset less than a dot diameter. The jitter algorithm is adaptable to a variety of implementation schemes. <IMAGE></p> |
