Abstract
An ink jet printing system includes an ink jet nozzle array for ejecting ink droplets during an ink jet printing cycle, and a flat medium positioned to receive ink droplets ejected by the nozzle array during an ink jet printing cycle. A motion apparatus provides relative motion between the nozzle array and the medium such that a spiral locus is defined by the nozzle array relative to the media during an ink jet printing cycle. The spiral maximum diameter may be made equal to the diagonal dimension of a rectangular media, thus allowing drops to be deposited very close to the edge of the media, and so reducing or eliminating the area of unprintable margins on both sides and the top and bottom of the media.
