Abstract:
A method of printing on a print medium with a printing mechanism having a print head with at least two nozzle arrays comprising steps of:printing with the nozzle arrays in a first printing mode, the first printing mode comprising the at least two nozzle arrays printing during a pass of the print head relative to the print medium, a second one of the nozzle arrays printing with a first density masking such that a portion of nozzles of the second nozzle array are prevented from printing during the pass;determining if a subsequent pass of the print head relative to the print medium requires printing from the first nozzle array; andswitching to printing in a second printing mode based upon a determination that the subsequent pass of the print head relative to the print medium does not require printing from the first nozzle array, the second printing mode comprising the second nozzle array printing without the first density masking during the subsequent pass.
