A gray component replacement method for each pixel of a continuous tone image, first obtains intermediate halftone colorant values by applying any suitable halftoning technique to continuous tone colorant values. Halftone output values at each pixel, including a black output value, are determined based on the intermediate halftone values. If desired, halftone output values can be determined based on both the intermediate halftone values and the continuous tone colorant values. <IMAGE> |
