The color reproducing device has matrix coefficients for a plurality of linear maskings, a linear masking is selected out of the plurality of linear maskings by the three color separation signals, the linear masking is carried out using the masking coefficients of the selected linear masking, and the color separated images are converted into density data that correspond to the recording color.
