目的 研究专色油墨的配色方法。方法 在K-M理论的基础上， 结合光谱配色法， 引入权重因子， 推导得出胶印油墨的配色模型。通过计算目标色块与匹配色块的色差对配色模型进行验证。结果 验证色块的色差均小于6， 符合忠实复制的要求。结论 采用此种方法建立的模型精度较高， 可用于配色。

The paper was aimed to build a model used in color matching of spot color ink. Based on K-M theory and weight factor method of spectrophotometric color matching, a model of color matching for offset printing ink was established. Through calculating the color difference between the sample and matching color, the model precision was tested. The color difference of matching color was less than 6, meeting the requirement of color reproduction. The model established using the presented method had a relatively high precision and could be used for color matching.
