 摘要：现代计算机配色通常由分光光度计和计算机配色软件组成，分光光度计测取颜色样品着色基质和染料等色彩的原始数据后经过计算机运算处理给出配方。当复制色和目标色之间由于原料性质和工艺参数等因素的影响存在较大颜色差异时，由计算机配色系统对所用配方进行修正，将色差控制在允许范围内。本文通过测取不同浓度油墨分别在80g胶版纸和157铜版纸的L、a、b值建立数据库，进行配色，经修正表明配方基本正确。并且讨论了配方色差较大产生的主要原因，提出了减少色差产生的措施，提高配色效率。

 Abstract: Modern computer color matching is usually color spectrophotometer and computer software, the color samples measured spectrophotometer colored dyes, such as matrix and the original color data processing is given through the computer formula. 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
