A Discussion on Printing Color Difference Tolerance by CIEDE2000 Color Difference Formula

摘要：

　　In ISO printing standards,a color difference tolerance of E*ab=5 is used as a threshold.But CIELAB color space is not uniform enough so that the same color difference value represents different color difference sensation in different color area.It is proved that the color difference calculated by CIEDE2000 is closer to the human sensation,so ISO TCI30 is discussing the possibility of replacing CIELAB color difference by CIEDE2000.An experiment was conducted,in which the color difference of typical printing colors,CMYKRGB,was calculated and test.The experimental results showed that the color difference tolerance of E*ab=5 is corresponding to 0.95~6.42 by CIEDE2000,with the average of 3.30 E*oo.So a color difference tolerance of E*00=3.3 or a somewhat looser value of E*00=3.5 can be adopted as a new tolerance for printing industry.
