摘要
在修正纽介堡方程基础上,将三刺激值配色法和光谱配色法相结合(简称"激谱配色法")对胶印专色油墨配色进行了理论与实验研究。根据网点扩大量修正法和指数修正法对纽介堡方程进行了修正,由三刺激值配色法和最小二乘法建立了配色的目标函数,通过求解函数的最小值得到油墨配方。实验结果表明,激谱配色法在进行配色计算时能满足实际配色的要求。
The offset spot ink color matching was studied in theory and practice by combining the tri- stimulus color matching and spectrophotometric color matching based on modified Neugebauer equation. The spectral model of Neugebauer equation was modified by means of dot gain values method and modified coeffi-cients method. The function is established according to the principle of tri-stimulus color matching and the least squares. The ink formulation was obtained by calculating the minimum value of equation. Experimental results indicated that the spectrophotometric color matching method can satisfy the demand of practical color matching.
