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 a contone image;
receive a first halftone threshold array;
receive alignment correction data; and
generate a halftoned print image based on the contone image, the first halftone threshold array and the alignment correction data by applying the alignment correction data to shift one or more of the contone image, the halftoned print image and the halftone threshold array based on one or more non-zero values of the alignment correction data;
wherein for non-zero values of the alignment correction data, the contone image and the halftoned print image are shifted in relation to each other and the halftone threshold array is shifted based on the alignment correction data.
