Abstract
Quality of printed images as produced by an ink-jet printer (10) is improved by staggering applications of ink dots (30) to pixel locations (36) such that overlapping ink dots are printed on successive passes of a printhead (16) and such that swaths (38) are partially printed on overlapping passes of the printhead. Quality of multi-colored or multi-shaded images is further improved by grouping pixels (36) into super pixels (42), and applying various combinations of colored ink dots to the various pixels within each super pixel in a staggered sequence.
