  • Patent number: 11570311
    Abstract: A printing system is disclosed. The printing system includes at least one physical memory device to store nozzle correction logic and one or more processors coupled with at least one physical memory device to execute the nozzle correction logic to receive a uniformity compensated halftone design for each of a plurality of pel forming elements, receive an average missing neighbor threshold lowering function, receive a defective nozzles list including one or more of the plurality of pel forming elements indicated as defective during print production and perform missing neighbor processing by applying the average missing neighbor threshold lowering function associated with a pel forming element determined to be a neighbor of a defective pel forming element.

  • Patent number: 11539857
    Abstract: A printing system is disclosed. The printing system includes at least one physical memory device to store calibration logic and one or more processors coupled with the at least one physical memory device to execute the calibration logic to generate a uniformity compensated halftone design for each of a plurality of pel forming elements, generate a missing neighbor corrected halftone design for each of the pel forming elements, generate a missing neighbor threshold lowering function for each of the pel forming elements based on the uniformity compensated halftone designs and the missing neighbor corrected halftone design and compute an average of the missing neighbor threshold lowering functions to generate an average missing neighbor threshold lowering function.
