When the target color and color reproduction between the nature of raw materials and process parameters and other factors when there is a big difference in color by computer color matching system used in formulation of an amendment to allow the difference in the scope of control. In this paper, measured in different concentrations of ink and paper 80g offset paper 157 of the L, a, b values of the establishment of databases to carry out color matching, as amended, shows that the basic right formula. And discussed the formula have the main reason for the larger color difference is proposed to reduce the chromatic aberration arising from measures to improve the efficiency of matching colors. Key words：Database; amendment; chromatism; matching efficiency
