Claim:
A method of printing an image onto a rotating media using a plurality of half-tone cells, comprising: providing a plurality of image points; dividing the rotating media into a plurality of annular bands along a radial direction of the rotating media, the annular bands being an integral number and each band having a width equal to a half-tone cell and being bound by two arcs; dividing each band into an integral number of half-tone cells so that each half-tone cell is bound by two opposing arcs and two opposing spokes originating from a center of the rotating media, wherein each half-tone cell has an associated plurality of screen dot patterns, and each screen dot pattern is associated with a specific intensity level; and for each selected half-tone cell, determining which image points are associated with the selected half-tone cells, selecting a screen dot pattern based on one or more intensity values of the associated image points, and dispensing ink objects onto the rotating media based on the selected screen dot pattern.
