Abstract
Apparatus and method reduce banding by addressing an image region at under 100% coverage, and adding colorant quanta to selected pixels already receiving that colorant. The amount of that colorant in some pixels is zero, in others a first nonzero number of quanta, in still others a second nonzero number—different from the first. In another aspect, the invention is a method of adding colorant in a region to which colorant is already addressed; it eliminates or reduces white- or light-line banding by automatically establishing a ratio, below half, of number of added-colorant pixels to total number of addressed pixels.
