计算机专色油墨配色模型初探

Preliminary Study of Computer Color Matching Model for Spot Color Ink

专色油墨在包装、防伪印刷等领域的应用日益广泛,计算机配色由于其众多优点越来越受到关注。配色模型作为计算机配色的核心部分,了解和掌握其配色理论具有重要的意义。本文介绍了基于纽介堡方程配色、基于三刺激值配色、基于光谱配色、基于蒙版方程密度法配色、基于复频谱色度理论配色等5种计算机专色油墨配色模型,对不同模型的特性进行阐述,分析各配色模型存在的局限性,并概述了基于Kubellka-Munk理论的计算机配色流程。最后对计算机专色油墨配色模型的发展思路进行了初步探讨。

Nowadays, Spot color ink is used widely in packaging, security printing and other areas. Computer color matching is more concerned due to its numerous advantages. Color matching model is the core part of computer color matching and color matching theory of color matching model should been understood. In this paper, five computer color matching models for spot color ink based on Neugebauer equation, tristimulus values, spectrum, masking equation, and complex frequency spectrum color theory were introduced. The characteristics and limitations of different color matching models were analyzed. Flow of computer color matching based on Kubellka-Munk theory was also described. Finally, the future development of computer color matching model for spot color ink was preliminarily discussed.
