摘要

研究多色打印机的反向光谱特征化

提出了一种空间细分插值的分色算法

提高了打印机颜色转换模型的精度。该算法结合颜色分区理论和胞元划分的方法

首先搜索目标颜色所属胞元空间

然后利用光谱纽介堡方程对胞元进行空间细分插值

并将满足阈值要求的插值点的通道信号值作为最终输出值。检测颜色样本的实验数据表明算法的分色精度高

平均色差达到1.013 NBS。新算法能够实现多色打印机从光谱数据到通道信号值的准确转换。

Abstract

A color separation method based on gamut space subdivision with interpolation was proposed to improve the precision of the color conversion model for multi-color printer's inverse spectrum characterization. Firstly

the algorithm combined gamut partition theory with cell space division method to find the cell space of the target color. Then

the cell space was subdivided by using spectrum Neugebauer equation

and the interpolation point's channel signal which met the threshold requirement was regarded as the final output values. The experimental data of the tested color samples showed that the algorithm had high accuracy with the mean color differences of 1.013 NBS. New algorithm could realize the accurate conversion of the multi-color printer from spectral data to channel-signal values.
