Abstract
A printing system is disclosed. The printing system includes 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 determine an uncalibrated deposition distribution for each of a plurality of pel forming elements, determine a calibrated deposition distribution for each of the plurality of pel forming elements and determine calibration values for each of the plurality of pel forming elements.
Claims20
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 measured data for a plurality of pel forming elements, receive a target response comprising a target ink deposition for the plurality of pel forming elements and determine calibration values for each of the plurality of pel forming elements based on average peak ink deposition value data included in the measured data, the target response and total ink deposition comprising an ink sum contributed by each of the plurality of pel forming elements at each of a plurality of locations, wherein the calibration values are implemented by one or more of the plurality of pel forming elements to print image data to a print medium.
A method comprising:
- receiving measured data for a plurality of pel forming elements;
- receiving a target response comprising a target ink deposition for the plurality of pel forming elements;
- and
- determining calibration values for each of the plurality of pel forming elements average peak ink deposition value data included in based on the measured data, the target response and total ink deposition comprising an ink sum contributed by each of the plurality of pel forming elements at each of a plurality of locations, wherein the calibration values are implemented by one or more of the plurality of pel forming elements to print image data to a print medium.
At least one non-transitory computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:
- receive measured data for a plurality of pel forming elements;
- receive a target response comprising a target ink deposition for the plurality of pel forming elements;
- and
- determine calibration values for each of the plurality of pel forming elements based on average peak ink deposition value data included in the measured data, the target response and total ink deposition comprising an ink sum contributed by each of the plurality of pel forming elements at each of a plurality of locations, wherein the calibration values are implemented by one or more of the plurality of pel forming elements to print image data to a print medium.
