Abstract
The number of pixels of a dot of a minimum size, a pattern frequency of an intermediate tone, the number of new dots of the minimum size at each dot percentage are determined. Then, thresholds in the threshold matrix are determined so that the optimum dot pattern at each dot percentage is obtained, and a threshold matrix is generated. A threshold matrix for C-separation is assigned to a separation for R that is complementary to C. A threshold matrix for M-separation is assigned to a separation for G that is complementary to M. A threshold matrix for Y-separation is assigned to a separation for B that is complementary to Y.
