OK. So: you take the first print to measure ALL inks limits, then you print a black 21-step print at the black ink limit, and you match the densities of the grey inks on this second print. Right? It's different from what I read on the net, but indeed it sounds more logical... Thx Paul!

Those gray ink limits are compared to a second 21-step test print of the black ink at it's ink limit, which was also determined from the first Calibration Mode print. Most people print a full second Calibration Mode print at this black ink limit. (I use another approach to save some paper. I use a manually-drawn straight line curve to print a separate 21-step test print. You'll see curves like this in my various Profile Zip files, named things like "K-0-45," for example, as the straight line curve that prints the black ink from 0 to an ink limit of 45.)
