Hi all. I am using an i1Pro Spectro to make a printer profile with ArgyllCMS. I already made a .ti3 file using: chartread -v -H -B -T0.4 name I found that a few patches had an high DeltaE2000 so I would like to read them again. I used: chartread -v -H -B -T0.4 -r name When I finish the reading I press d but I get this error: chartread: Error - The resumed spectral type seems to have changed! And I can't save the new .ti3 file. Can you please explaing this error and tell me what I can do? Thanks. Vittorio Villani
