Excellent ink jet print quality can be obtained by printing an entire line in one pass using, e.g., a 40-jetin-4inearray to achieve a density of 240 drops/inch on a 1/6 inch high line. However, this array is expensive and difficult to fabricate. Similar quality can be achieved with a reduced number of jets and multiple passes. For example, use 20 jets spaced apart at 1/120 inch, printing two passes per line and incrementing the jet on the paper 1/240 inch between passes. If the jet spacing 1/120 inch is defined as A , the paper incrementsX /2 between stitching passes.
