ABSTRACT:
A method is implemented in a halftone printing system that permits a halftone dot to be represented by an envelope that is formed from a combination of straight lines that are drawn from tangent points, on the outer periphery of the dot, through reference axis for the dot. The intersection points of the tangent lines on the reference axis define the size (density) of the dot. Storing the intersect points as sets of values for each size dot provides a unique representation set that is used to reconstruct a selected dot size for printing a halftone image.
