Hi Bill, Granted I'm not at my most alert today and may have missed something, but did you say whether all measurements were made from the same control patches, or to put it another way, does your profiling chart actually contain the patches you're discussing? If it doesn't, and smaller charts do not, then the figures taken from the press profile and therefore accessed by for your proofer are interpolated and inaccurate. Same with TVI, of course: You see a certain gain, for example, on a 3% dot in your control bar and lower gain in the profile. The profile may also show density below the actual minimum dot, which is why proofing RIPs have a setting to override the source profile and let that 1-2% drop out. But maybe I've misconstrued your question. It's happened before. Mike Strickler MSP Graphic Services

Greetings,

FYI - I recently posted this to Print Planet. I am a flexo printer and have created a profile using iProfiler for a poly stock which has a very high TVI. In order to make an accurate proof I had to build what I would call, an extreme gradation in my CGS proofing workflow, which led me to believe the profile is not accurately reporting my highlight TVI.

I checked the TVI on press sheet with a 530; in ColorAnt using the measurement file; and, in ColorThink using the profile. ColorAnt matches the TVI in highlights that the press printed, but the profile in ColorThink does not. Here is the data for cyan:

1.96%: ColorAnt 26% Press 24% ColorThink 7% @1%, 13% @2%

2.75%: ColorAnt 30% Press 29% ColorThink 14% @2%, 20% @3%

4.71%: ColorAnt 36% Press 35% ColorThink 27% @4%, 32% @5%

I have had some feedback as to why this is happening, but would appreciate some more. Additionally, is editing the profile in something like Profile Editor, which I still own, the only way to fix this. In my limited experience using iProfiler I do not see a way to make edits such as these to a profile.

Thanks.
