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 determine an uncalibrated ink deposition distribution for each of a plurality of pel forming elements based on measured data, determine a calibrated ink deposition distribution for each of the plurality of pel forming elements based on a target response including generating a total ink deposition based on an ink sum contributed by each of the plurality of pel forming elements and determining calibrated average peak values for each of the plurality of pel forming elements to achieve the target ink deposition, and determine calibration values for each of the plurality of pel forming elements, wherein the target response comprises a target ink deposition.
A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:
- determine an uncalibrated ink deposition distribution for each of a plurality of pel forming elements based on measured data;
- determine a calibrated ink deposition distribution for each of the plurality of pel forming elements based on a target response, including:
- generating a total ink deposition based on an ink sum contributed by each of the plurality of pel forming elements;
- and
- determining calibrated average peak values for each of the plurality of pel forming elements to achieve the target ink response, wherein the target response comprises a target ink deposition;
- and
- determine calibration values for each of the plurality of pel forming elements.
A method comprising:
- determining an uncalibrated ink deposition distribution for each of a plurality of pel forming elements based on measured data;
- determining a calibrated ink deposition distribution for each of the plurality of pel forming elements based on a target response including:
- generating a total ink deposition based on an ink sum contributed by each of the plurality of pel forming elements;
- and
- determining calibrated average peak values for each of the plurality of pel forming elements to achieve a target ink deposition, wherein the target response comprises a target ink deposition;
- and
- determining calibration values for each of the plurality of pel forming elements.
