Hello Vittorio, > is it possibile to print a chart set using the profile that I made and read > them and then use profcheck to see how far the patches are from the right Lab > values? as far as I know, this is exactly what profcheck is meant for. From the documentation: "The absolute forward table in the profile is used to create PCS values from the sample points, and the profiles PCS value then compared to the PCS values of the measured sample points."
