Digital BW, The Print

I've tested some of Roark's profiles using UT2 inks and  Innova Fiba  
Gloss and found that the one for EPSG with PK  seems to work very  
well, however, there is still some gloss differentiation to be seen.  
Does anyone know if there is a way to use glop with this. If I  
replace the yellow cartridge with glop and use the pk profile will it  
affect the situation, or does it only work with eboni? The profile  
for eboni caused huge gloss diff and required some other adjustments  
as well.
