摘要： 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.
