Abstract:
In S100, multilevel density data C, M, Y, and K for a subject pixel are read out from the data recording medium. Then, the total ink density ND is calculated in S110. It is judged whether or not the total ink density ND is higher than the predetermined limit value L1. When the total density ND is not higher than the value L1 (no in S120), the original density data C, M, Y, and K for the subject pixel are subjected to the binarization process in S140. When the total density ND is higher than the value L1 (yes in S120), on the other hand, the value of the multilevel data for each chromatic color component is reduced through an ink density reduction process in S130. The thus obtained reduced multilevel data C3, M3, and Y3 and the black multilevel data are subjected to the binarization process in S140.
