Abstract: The memory size and processing time for the correction of image data carried out to reduce image deterioration caused by nozzle ejection characteristic variation in an inkjet printing apparatus can be minimized. Print heads are provided with pluralities of chips that have nozzle arrays formed from a plurality of nozzles. Overlap portions and non-overlap portions are formed on each chip. An image processing apparatus sets input image data, corresponding to nozzle regions that are defined in nozzle arrays along the alignment direction of the nozzles of the print head and that are composed of a plurality of nozzles, as processing blocks. The input image data is processed according to parameters defined for each of those processing blocks. The boundaries of the nozzle regions corresponding to the input image data of the processing blocks are established according to the boundaries of the overlap portions and the non-overlap portions.

Abstract: A method for monitoring stitching between two adjacent printheads includes capturing one or more images of content printed on a moving print media in at least a stitch boundary or overlap region to obtain pixel data. The pixel data is then averaged in a media transport direction to produce blur in an image or images. Derivative data of the averaged pixel data is determined and one or more peaks is detected in the derivative data. A type of stitching artifact is determined based on the detected peak in the derivative data.

Abstract: A laser scanning assembly generates a laser beam and scans the laser beam through a plurality of scan lines to form desired dots. Each scan line is positioned to overlap an adjacent scan line and each dot includes a plurality of segments. The scanning assembly scans the laser beam through multiple scan lines to fully discharge each segment of each dot. The laser scanner assembly would typically be part of a laser printer.

Abstract: A method of generating half tone print data is disclosed. The method starts by determining an extent of overlap caused by temperature variations of overlapping end portions of a pair of consecutive printhead segments. A dither value is also generated from a dither matrix, and the dither value is combined with the extent of overlap to produce an output value. A mathematical operation is performed on continuous tone print data based on the output value, to produce the half tone print data.
