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, including receiving print image measurement data corresponding to primary color markings and secondary color markings printed by pel forming elements, wherein each of the pel forming elements is associated with one of a plurality of primary colors, generating a first set of transfer functions, wherein the first set of transfer functions include a transfer function for each of the pel forming elements associated with a primary color, generating a second set of transfer functions, wherein the second set of transfer functions include transfer functions for each of the pel forming elements associated with a plurality of secondary colors and generating a set of uniformity compensated transfer functions, wherein the set of uniformity compensated transfer functions include a transfer function for each of the pel forming elements based on the first set of transfer functions and the corresponding second set of transfer functions.

摘要： A system is disclosed. The system at least one physical memory device to store image texture analysis logic and one or more processors coupled with the at least one physical memory device, to execute the image texture analysis logic to receive first image data associated with a first nozzle group and second image data associated with a second nozzle group and analyze the first and second nozzle group image data to determine whether a difference between a texture of the first image data and a texture of the second image data exceeds a predetermined threshold, wherein the first nozzle group and second print head are neighboring nozzle groups.
