    摘要: 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 perform uniformity compensation of a plurality of secondary colors printed by pel forming elements, each of the pel forming elements associated with one of a plurality of primary colors, including generating a uniformity compensated first primary color halftone design for each of the pel forming elements associated with a first primary color and a uniformity compensated second color halftone design for each of the pel forming elements associated with a second primary color based on an inverse transfer function corresponding to a first secondary color, generating an updated uniformity compensated first primary color halftone design for each of the pel forming elements associated with the first primary color and a uniformity compensated third primary color halftone design for each of the pel forming elements associated with a third primary color based on an inverse transfer function corresponding to a second secondary color and generating an updated uniformity compensated second primary color halftone design for each of the pel forming elements associated with the second primary color and an updated uniformity compensated third primary color halftone design for each of the pel forming elements associated with a third primary color based on an inverse transfer function corresponding to a third secondary color.

    摘要: A printing system is disclosed. The printing system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to receive measurement data corresponding to a print medium printed with a plurality of non-functioning pel forming elements, a plurality of functioning pel forming elements and a plurality of tint levels; wherein adjacent ones of the plurality of functioning pel forming elements print with compensated halftone designs applied to pels adjacent to the plurality of non-functioning pel forming elements, associate measurement data with the plurality of non-functioning pel forming elements, corresponding compensated halftone designs and the plurality of tint levels and determine optimal compensation by selecting the compensated halftone designs that have corresponding measurement data values closest to compensation target values for each of the plurality of tint levels.
