Abstract
An ink jet printer apparatus and method of printing wherein image data representing a predetermined number of gray levels of pixels to be printed are accommodated in an inkjet printer for recording on a receiver medium. The printer has the capability of producing fewer numbers of gray levels at respective pixel positions than the data requires. The inkjet printer prints an increased number of the gray levels by applying multitone printing to pixels locations on a reference raster and provides supplementary ink drops to respective adjacent pixel locations on a shifted raster.
