Abstract
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 receive operating point data corresponding to an image processing system, receive a full range transfer function corresponding to an image processing system and generate a sub range transfer function corresponding to the image processing system for each of a plurality of digital count values based on the operating point data and the full range transfer function.
Claims20
A system comprising:
- 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:
- receive operating point data corresponding to an image processing system;
- receive a full range transfer function corresponding to the image processing system;
- and
- generate a sub range transfer function corresponding to the image processing system for each of a plurality of digital count values based on the operating point data and the full range transfer function, wherein the sub range transfer function comprises a plurality of digital count values calibrated to a first optical density target value indicated by the operating point data and a transfer function is applied to image data during printing of the image data.
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 operating point data corresponding to an image processing system;
- receive a full range transfer function corresponding to the image processing system;
- and
- generate a sub range transfer function corresponding to the image processing system for each of a plurality of digital count values based on the operating point data and the full range transfer function, wherein the sub range transfer function comprises a plurality of digital count values calibrated to a first optical density target value indicated by the operating point data and a transfer function is applied to image data during printing of the image data.
A method comprising:
- receiving operating point data corresponding to an image processing system;
- receiving a full range transfer function corresponding to the image processing system;
- and
- generating a sub range transfer function corresponding to the image processing system for each of a plurality of digital count values based on the operating point data and the full range transfer function, wherein the sub range transfer function comprises a plurality of digital count values calibrated to a first optical density target value indicated by the operating point data and a transfer function is applied to image data during printing of the image data.
