The thickness of CMYK patches printed by IGT C1 was calculated and the Lab values of the patches were collected. The relationship between ink thickness and Lab values was established by using multiple linear regression method in Matlab. Experimental results showed that the linear relationship between CMY ink thickness and Lab values is significant.
