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 for the plurality of pel forming elements and determine calibration values for each of the plurality of pel forming elements based on the measured data, the target response and total ink deposition at each of a plurality of locations, wherein the target response comprises a target ink deposition and the total ink deposition is an ink sum contributed by each of the plurality of pel forming elements.
A method comprising:
- receiving measured data for a plurality of pel forming elements;
- receiving a target response for the plurality of pel forming elements;
- and
- determining calibration values for each of the plurality of pel forming elements based on the measured data, the target response and total ink deposition at each of a plurality of locations, wherein the target response comprises a target ink deposition and the total ink deposition is an ink sum contributed by each of the plurality of pel forming elements.
The method of claim 12, wherein the calibrated halftone design comprises a calibrated threshold array.
At least one 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 for the plurality of pel forming elements;
- and
- determine calibration values for each of the plurality of pel forming elements based on the measured data, the target response and total ink deposition at each of a plurality of locations, wherein the target response comprises a target ink deposition and the total ink deposition is an ink sum contributed by each of the plurality of pel forming elements.
