An ink jet print head includes an array of nozzles, each nozzle being capable of selectively producing when actuated at least two ink drop sizes including a larger ink drop size and a smaller ink drop size. In response to a pixel density signal of maximum density value at a respective pixel location, a nozzle prints a drop of the larger ink drop size at the respective pixel location on a reference raster and the same or a different nozzle prints a drop of a smaller drop size at a pixel location adjacent to the respective pixel location on a shifted raster to provide for full coverage with improved dry time capability of the printed ink drops.
