针对包装印刷中胶印专色油墨精确配制这个瓶颈问题，以X-RiteColor Master油墨配色系统为平台，进行了专色油墨精确配制的方案设计和实验。研究结果表明，配色系统色种数据库的建立与优化、标准墨色分光光谱数据的采集、面向印刷条件和样本的配方筛选，是专色油墨精确配制的关键。建立的专色油墨精确配制方案，不仅配色精度高、速度快、色差小，而且适合实际生产应用。

A scheme of spot color ink accurate matching was designed and tested with X-RiteColor Master ink matching system solve the bottleneck problem of spot color ink accurate matching. The results showed that the establishment and optimization of database basic ink of color matching system, the collection of standard ink spectral spectrum, and the formula screening of facing the printing conditions and sample is the key to get satisfactory accurate spot color ink. The spot color ink accurate matching scheme is not only accurate matching, fast speed, and small color difference, but also suitable for actual production application.
