You are using the Piezography Methodology 3 ink set, right? If your are not getting the results you want with this inkset and the Cone profiles you can always create your own profile with the regular QTR tools. The existing Cone profiles for the Methodology 3 system basically are designed to give negatives with a defined density range, but you must adjust for input/output with an .acv curve. If you write your own profile for the Methodology 3 ink set you can insert both density range and linearization directly into the profile.
