Abstract
A method for reducing visual printing defects produced by an ink jet printer includes the steps of providing a first printhead nozzle array spaced apart from a second printhead nozzle array in a main scan direction; defining a plurality of rasters for scanning during a first unidirectional scan of the first printhead nozzle array and the second printhead nozzle array; and printing on a print medium with both the first printhead nozzle array and the second printhead nozzle array to form printing lines traced along at least a portion of the plurality of rasters during the first unidirectional scan, wherein the first printhead nozzle array is controlled to print in a first shingling pattern and the second printhead nozzle array is controlled to print in a second shingling pattern.
