the numbers before match the sample taken in your scan/photo the numbers after match the CMYK values (that are based upon MY settings) given in the greyscale caibration file (...the curves of a 3D lady escape my grasp ( for I don't use poser yet, maybe i should ;^_^ ) ...you could use a screenshot to retain the calibrated file's information, to keep it digital... ) I just hope it's understood, you will change up to 3 areas of the tones , with curves, in each of the four channels. (numbers veriate, but the the result will suit your cmyk needs)
