Hi Nikolay I roughly understand the difference between -I and -K options and I realize that RIP calibration is better than applying it to profile.... but one thing is bothering me. Isn't it redundant/harmful to supply the same calibration data twice into the main profile workflow: - first time: indirectly via preliminary profile as targen -c parameter (If preliminary profile has calibration applied then targen -c with -A > 0 generates color domain already corrected by calibration in some degree) - second time: directly via printtarg -K/-I parameter Michał
