基于色域划分的多通道打印机色彩校正

Multi-Channel Printer Characterization Based on Gamut Partition

针对多通道喷墨打印机,提出一种将打印色域划分并在分割后的子区域内实施色彩校正的算法.首先建立打印机的呈色模型,进而分析了高维颜料空间的光谱冗余及色域划分的可行性,在此基础上设计色域划分方法,并对每个子区域实施色彩校正.区域划分降低了数据维数,消除了颜色冗余,且算法不受打印机颜料数目的限制.

This paper proposed a multi-channel ink jet printer characterization algorithm by printer color gamut partition and subspace color calibration.First,a printer model is created,then spectral redundancy of the high dimensional colorant space and feasibility of gamut space partition is analyzed.After that,gamut partition method is designed to divide the printer＇s gamut into several parts and color calibration is done in each partition.Partition reduces the data dimension and eliminates color redundancy.This method has the advantage of wide-use and no limitation to ink channel numbers.
