Abstract
System and methods for using a fluid ejection system to distribute fluid drop density of a region between at least two overlapping swaths having pixels on a receiving medium. Using the method, overlapping swaths are stitched together by distributing a fluid ejection pattern between the overlapping swaths within the overlapped region. Because small drops of fluid can be distributed within a single region, the fluid ejection pattern can be controlled and intermediate density regions can be created by distributing the fluid of drops within a region between two fluid ejector heads or between two swaths of the same fluid ejector head. The distribution can be linear or non-linear. Furthermore, overlapping swaths are stitched together by randomly varying a stitch location within the overlapped region. In this case, a stitch location is randomly varied in the slow scan direction.
