A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate transfer functions for each of a plurality of color planes to compensate for overlapping pel forming elements of adjacent printheads, wherein the transfer functions are generated based on ink deposition functions for groups of pel forming elements including non-overlapping pel forming elements and the overlapping pel forming elements, wherein the transfer functions transform input digital counts, and wherein the ink deposition functions represent output ink amount versus input digital count.

A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate transfer functions for each of a plurality of color planes to compensate for non-functioning pel forming elements, wherein the transfer functions are generated based on ink deposition functions for groups of pel forming elements including functioning pel forming elements and the non-functioning pel forming elements, wherein the transfer functions transform input digital counts and the ink deposition functions represent output ink amount versus input digital count.

Print artifact compensation mechanism

A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate first ink deposition function representing a first output ink amount versus input digital count for each of a plurality of color planes, generate second ink deposition function representing a second output ink amount versus input digital count for each of the plurality of color planes and generate transfer functions for each of the plurality of color planes based on the first ink deposition function and the second ink deposition function, wherein the transfer functions transform input digital counts.

A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate first ink deposition function representing a first output ink amount versus input digital count for each of a plurality of color planes without pel forming element artifacts, generate second ink deposition function representing a second output ink amount versus input digital count for each of the plurality of color planes with the pel forming element artifacts and generate compensated halftones for each of the plurality of color planes based on the first ink deposition function and the second ink deposition function.

A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate inverse transfer functions for each of a plurality of color planes to compensate for overlapping pel forming elements of adjacent printheads based on ink deposition functions for groups of pel forming elements including non-overlapping pel forming elements and the overlapping pel forming elements, wherein the inverse transfer functions transform output digital counts and the ink deposition functions represent output ink amount versus input digital count and generate compensated halftones for each of a plurality of color planes based on the inverse transfer functions.
