Special stochastic screens are generated to eliminate the moir+E,acu e+EE between stochastic screens and checkerboard inputs. Using the checkerboard pattern, we can divide the entire stochastic screen S into two subsets: S1 is defined by all pixels, which lie on the white half of the checkerboard, and S2 is by the black half. The design of a stochastic screen is a mathematical optimization process, which as a single-value merit function as Q(S), so the design process can be described as maximizing Q(S). To eliminate the moir+E,acu e+EE between the checkerboard input and the stochastic screen, the same design criteria to the two subsets, S1 and S2, individually, as well as to the entire set S is applied.
