Hmmm. It’s hard to say without seeing your data.
At first glance I’d guess that you were plugging “measured” values into the RIP where it wants “wanted” values or vice-verse?
Feel free to submit your measurement files, screenshots - and whatever else we might need in order to understand what you’re dealing with - into the Feedback System (under Curve2.0 > Feedback System) and that will get to us so we’ll take a look.
