ABSTRACT:
A computerized method for improving ink-jet print quality. A jittered print mode is instigated to scatter print errors 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 of ink droplet firing time 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.
