Abstract
A method of printing on an inkjet printer including a plurality of overlapping jetting modules includes analyzing image data within a stitch area to designate white pixels and non-white pixels. For rows where the stitch area includes white pixels, a hard stitch boundary is defined within the stitch area where image pixels to the left of the hard stitch boundary are to be printed using a left jetting module and image pixels to the right of the hard stitch boundary are to be printed using a right jetting module. For image regions where the rows of image pixels within the stitch area include only non-white pixels, a soft-stitching path is defined through the image region, and a fading function is used to gradually transition from printing image pixels with the left jetting module to printing image pixels with the right jetting module in a transition zone around the soft-stitching path.
