EFI Colorproof XF spot color overprints...I'm not happy!

[schenkadere]

I bit the bullet and upgraded to EFI 4.0.1. There is a definite improvement in spot color rendering, spot color overprints as well as interface and workflow tools. It seems a touch squirrelly...maybe a bit buggy...but I'm sure it will all get worked out.

Definitely worth the $599.

Hello!
I want to raise almost exactly the same problem.
We run EFI XF 4.1 with PDF Output option.
The problem: Spots overprint looks different on the Epson printouts and in the PDF output.
In PDF, the spots overprint looks like we expect to see them; on the paper it looks too light.
We have played with that odd gamma/global settings with no luck: we have right 100% but wrong tints or we have pleasant tints and overprint but wrong 100%.

I agree with that sentences about the complexity of spot overprints in real printing world;
BUT - we are very pleased with PDF output result! How we can obtain the same on paper??
Attached: spotOK-PDFout.jpg - PDF Output result; spotError-epsonPAPER.jpg - scan of the paper printout of the same proof with the *same* workflow colour settings.

PS. Sorry for my broken English

I messed around with every different overprint setting until I just settled on global 90% gamma .8
