ABSTRACT:
Perceived quality of printing dot-on-dot graphics area fill using an ink-jet device is improved by printing swaths (30, 32, 34, 36, 38) of alternating colors, with each swath offset from the preceding swath by a predetermined amount. In this manner, banding (22, 22'), which is perceived with prior art printing methods, is substantially reduced.
