A system comprising: at least one physical memory device to store halftone calibration logic; and one or more processors coupled with the at least one physical memory device to execute the halftone calibration logic to: receive print image measurement data corresponding to a first halftone design comprising a set of threshold values for each of a plurality of pel forming elements in a sheetside bitmap; generate nozzle measurement data by interpolating the print image measurement data for each color value for each of the pel forming elements based on the print image measurement data; generate a uniformity compensated halftone for each of the pel forming elements based on inverse transfer functions corresponding to each of the pel forming elements and the first halftone design, wherein each inverse transfer function comprises a mapping from an output gray level or color value to an input gray level or color value representing the pels in a bitmap; generate, from the uniformity compensated halftone, a refined uniformity calibrated halftone which compensates for marking differences of the pel forming elements, wherein the refined uniformity calibrated halftone is generated by performing an iterative process, where each iteration uses the halftone from the previous iteration to print markings that are measured and used to generate a current uniformity compensated halftone; and transmit the refined uniformity compensated halftone for each of the pel forming elements. at least one physical memory device to store halftone calibration logic; and one or more processors coupled with the at least one physical memory device to execute the halftone calibration logic to: receive print image measurement data corresponding to a first halftone design comprising a set of threshold values for each of a plurality of pel forming elements in a sheetside bitmap; generate nozzle measurement data by interpolating the print image measurement data for each color value for each of the pel forming elements based on the print image measurement data; generate a uniformity compensated halftone for each of the pel forming elements based on inverse transfer functions corresponding to each of the pel forming elements and the first halftone design, wherein each inverse transfer function comprises a mapping from an output gray level or color value to an input gray level or color value representing the pels in a bitmap; generate, from the uniformity compensated halftone, a refined uniformity calibrated halftone which compensates for marking differences of the pel forming elements, wherein the refined uniformity calibrated halftone is generated by performing an iterative process, where each iteration uses the halftone from the previous iteration to print markings that are measured and used to generate a current uniformity compensated halftone; and transmit the refined uniformity compensated halftone for each of the pel forming elements. receive print image measurement data corresponding to a first halftone design comprising a set of threshold values for each of a plurality of pel forming elements in a sheetside bitmap; generate nozzle measurement data by interpolating the print image measurement data for each color value for each of the pel forming elements based on the print image measurement data; generate a uniformity compensated halftone for each of the pel forming elements based on inverse transfer functions corresponding to each of the pel forming elements and the first halftone design, wherein each inverse transfer function comprises a mapping from an output gray level or color value to an input gray level or color value representing the pels in a bitmap; generate, from the uniformity compensated halftone, a refined uniformity calibrated halftone which compensates for marking differences of the pel forming elements, wherein the refined uniformity calibrated halftone is generated by performing an iterative process, where each iteration uses the halftone from the previous iteration to print markings that are measured and used to generate a current uniformity compensated halftone; and transmit the refined uniformity compensated halftone for each of the pel forming elements.
