1. A method for designing a plurality of correlated stochastic screens intended for use in color-halftoning, the method comprising: associating a merit function with each screen, said merit function representing a measure of the desirability of the screen; associating additional merit functions with selected combinations of the screens, said additional merit functions representing a measure of the desirability of the screen combinations with regard to ink-dispersion and combined spatial-frequency response; and, constructing the plurality of screens to optimize the merit functions.
