ABSTRACT:
An apparatus and method for producing a halftone image which generates halftone cells based on grayscale image data values. Each of the halftone cells is formed from serpentine dot patterns. The serpentine dot patterns form two separate arcs. The halftone cells are written onto a recording medium to produce the halftone image. Rotation of the halftone cells allows data to be encoded within each of the halftone cells without varying the tone of the image. The tone of the image may be controlled by selectively varying a thickness of the arcs within the halftone
