摘要： One aspect of the invention lowers boundary artifacts by depleting selectively at a boundary, only in high-color-saturation areas. In another aspect, printmasking defines depletion regions. In yet another, a printer treats different drop-to-pass allocations as of opposite sign. Some preferred embodiments exploit the multilayer Shakes mask system: each mask represents a number of drops to fire, and masks are additive, depending on image content. In preferred embodiments the high-value mask is used in opposition, reducing the number of drops to fire. Bits are set in this mask at pixels close to boundaries, to define depletion regions that negate artifact-causing boundary coalescence. An adaptive version measures nonuniformity in an area-fill test pattern, and uses results to define localized depletion bits for high-value mask(s).

摘要： One aspect of the method/apparatus finds, for each input-image pixel, an “offset weighted average” of neighboring-pixel interactions—and uses the averages to make a final image. Another aspect assumes a value for each pixel, to use in a final rendered image form—and, at each in a series of approximations, determines whether to change the value, and finds a probabilistic weight to help determine. Yet another finds, for each pixel, a numerical representation of neighboring-pixel interactions—and establishes a distance cutoff for use in defining “neighbor”, and uses the representation to decide whether to change color values. Still another finds a desired or ideal number of print passes, and adapts the number of passes actually used to the found number. Another combines halftoning and printmasking into one procedure and prints images prepared thereby. Another integrates halftoning and image filtering, to obtain esthetic visual effects, into one procedure—and prints images thus prepared.

摘要： A method for preparing a mask for multi-pass printing, comprises determining a characteristic satellite drop spray pattern for printing in a multi-pass mode with a printhead. Positions in the mask are filled with pass numbers. The pass numbers in a given position are selected based on considerations of interactions among main drops and satellite drops.

摘要： A technique for assessing nozzle health of a printhead nozzle array in a printing system includes printing a swath portion of an image, optically scanning the printed swath portion to capture a scanned image, comparing an expected image of the swath portion of the image with the scanned image, and assessing whether any nozzles of the nozzle array have malfunctioned. A sensor can be mounted on a printhead carriage to accomplish the image capture.

摘要： When condition of a printing element (e.g. inkjet nozzle) changes, essentially full mask rows invoking the element are redone from scratch, best so as to fully satisfy pixel-grid neighbor conditions. This is faster than redoing a whole mask as in prior popup or precook /reheat methods, and yields better printouts than prior row-by-row mask revision (e.g. directly replacing a weak nozzle by a good one across whole rows). This method is best independent of prior mask versions, and uses no prebuilt matrix of backup/alternate entries. The number of rows redone is typically 7% to 14% below a nominal/baseline value.
