ABSTRACT:
A method and apparatus of printing with a liquid ink printhead ejecting ink in swaths on a recording medium to form an image including a plurality of dots deposited at pixel locations of a scanline. The printer deposits a plurality of dots at adjacent pixel locations on the scan line during non-consecutive swaths of the printhead to form the image. Dot interaction between dots is minimized so that no two dots are deposited adjacent to each other in consecutive depositions of the dots of consecutive swaths of the printhead. Reduction of ink bleeding, printhead signatures such as banding, and other defects caused by clogged nozzles of the printhead are reduced.
