In an example print system including a mask engine and print engine, the mask engine is able to cause generation of print masks with disabled sections that are non-overlapping. In an example method of printing, a number of passes over a zone of media is identified, a plurality of print masks corresponding to the zone are generated with a disabled section of pixels that are non-overlapping, and the number of passes are printed based on the plurality of masks such that the disable pixels in each print mask are in a different relative position with respect to a location of the media.
