Abstract
A method for printing in an image forming system is disclosed. The method, in combination with an apparatus printhead, suppresses defects in printed images. When an image forming system prints an image or group of images in a swath by swath manner, there is a tendency for minor printing defects to arise based on poor alignment of the printhead or ink ejectors, or an error in the instruction software. The printing defects can be defects such as unwanted white spaces or lines, or unwanted bold areas or overlapping swath edges. The present invention utilizes the edges of the swaths to insert a stitch line between the swaths having a different number and size of pixels printed, to allow for modification of the stitch line after measuring an actual advance of a printing medium between each instance of a swath. The same image data line provides the instructions to print both the first and second portions of the stitch line, between each swath.
