Dear List, Suppose I need to check a printer profile for reproduction of a set of about 500 pre-determined colours; colours being defined as XYZ D50 2 degree. As a first step, I filter off the colours that are out of gamut using xicclu -fif -ia -pX Next, for those XYZ that fall into the gamut I convert them to RGB xicclu -fb -ip -pX From the RGB list I make a target formatting to CGATS and using ColorPort, print it, measure it, and compare resulting XYZ numbers to source XYZ. Any better ideas, suggestions, improvements, please? -- Iliah Borg ib@xxxxxxxxxxx
