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:
receive measurement data corresponding to a print medium printed with a plurality of pel forming elements in adjacent printheads and a plurality of tint levels, wherein the plurality of pel forming elements comprise gap adjacent pel forming elements that print with applied compensation transfer functions and non-gap adjacent pel forming elements;
associate measurement data values with the gap adjacent pel forming elements, the applied compensation transfer functions and the plurality of tint levels; and
determine optimal compensation by selecting the compensation transfer functions that have corresponding measurement data values closest to compensation target values for each of the plurality of tint levels.
