摘　　要：该文针对三刺激值配色存在的不足,结合专色印刷的特点,提出了一种基于粒子群优化的专色油墨配色算法,用于解决算法中求解配方时矩阵运算存在的问题。为验证所提算法,实验通过随机选取已知配方的4组标准样品,与算法计算结果进行比较,结果表明:所有计算的配方经打样后得到的样品与标准之间的色差均控制在5以内,满足印刷行业标准要求。In this paper,a spot color matching algorithm based on particle swarm optimization（PSO） is presented.According to the characteristics of spot color printing,the interpolating method for obtaining the unit K / S value is modified based on cubic spline.Since the PSO algorithm could ensure a good rate of convergence without premature convergence to a local optimum,when solving the formula in color matching,it is proposed to settle the constraint optimization problem in matrix operation.To evaluate the performance of the proposed approach,five different colors have been selected as standard samples,and the color difference between standard samples and the results obtained from presented algorithm is within the prescribed limit.
