Abstract
A method and associated apparatus is implemented for utilization in a halftone printing system to permit a halftone dot to be written with multiple density levels. These multiple density levels are used to from a variable density dot edge profile. This implementation is particularly adapted for use with systems that represent halftone dots with 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. The intersect points are stored as sets of digital values for each size dot to provide a unique representation set that is used to reconstruct a selected dot size for the printing of a halftone image.
