First, start with the uncoated curves:
38-Uncoated-Master-Cool.quad (6.2 KB)
38-Uncoated-Master-Neutral.quad (7.3 KB)
38-Uncoated-Master-Warm.quad (6.1 KB)
These curves were made by loading a hahnemuhle photo rag curve into the starting curve, deleting the measurements entirely, and then going to the limiter and limiting everything down to 50% except for the darkest tones which were kept at 100%. That is a different way of limiting ink that with QTR which limits the darkest tone as well.
Then a target was printed with these new limited curves and then the curves were linearized.
Basically if you print a target and see the pooling/rippling in certain tonal areas you can load that curve into the tool and limit those specific tonal areas DOWN. Then you linearize.
