Digital BW, The Print

I have been trying to get decent results using ImagePrint 5 with Cone 
PiezoTone Selenium inks in a 7000.

I have tried various settings, Piezo 1 and Piezo 11 ink settings, 
different paper settings, but in each case, using the supplied 
profiles, the shadows are completely blocked.  I mean, it looks like 
someone has painted dense black ink in them.  Only the shadows seem 
to be a problem.  Makes the Epson driver's shadows look open, its 
that bad.

If anyone else is succesfully using ImagePrint 5 with Piezotone, or 
even the original Piezo inks, I'd apreciate hearing from you - I want 
to check my settings against yours.  

Thanks

Quentin
