Abstract
An inkjet printer that is configured to perform multi-pass printing operations includes at least one printhead, a memory and a controller. The controller receives a input row of image data for one pass including a plurality of pixels. The controller uses a table of index lookup offsets in the memory to generate a row of output image data with at least one pixel at a first index in the input row being located at a second index in the output row. The controller operates the inkjets in the printhead to eject at least one drop of ink using an inkjet in the printhead that corresponds to the second index in the output row and that is different than another inkjet in the printhead that corresponds to the first index in the input row.
