1. A system comprising:
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 wherein the ink deposition functions represent output ink amount versus input digital count.
