Hi Bill, You can use PM5's profile editor to alter the proof--hard and soft--without changing the output separation. Elect to edit the device-to-Lab LUTs only, go to the Gradation dialog and put your curve in there. Afer a ittle trial and error you'll get the desired result. Call me if you have any further questions. Mike

(If this double posts I am sorry) Greetings - I am a flexo printer and I need an accurate profile for a stock that has a very high TVI - 1% gains to 22%. I checked TVI by both measuring the press piece with a Spectro/Densitometer and looking at the measurement data in ColorAnt. Both methods agree with the TVI number.
I check the TVI in the profile by: 1. Applying the profile to the reference file using ColorThink; Saving the results and looking at them in ColorAnt. 2. Opening the profile in ColorThink and looking at Dot Gain under the Curves tab.
Both methods indicate that the 1% gain in the profile is about 5%.
While I have been able to make an accurate proof using a very highlight bump curve in CGS Tuner, I now need to adjust the profile so my customer can use it to soft proof the RGB files that are being created.
I have a copy of Profilemaker 5.10 with editor and have made a few, failed, attempts to adjust my profile.
How can one adjust a profile to meet my needs of a 1% gaining to a 22%? Or, how can I make iProfiler honor the true TVI in this profile?
