The "UltraPremGPP" curve uses the glop.  The "Kirkland" curve does 
not.  You might see if there is a difference in prints between these 
2.  Maybe the glop channel is not working.

Note that the Epson driver settings are different for glossy and 
matte papers if you're using the supplied PS curves or ICCs.  (I did 
not supply any QTR rip profiles.)  
See p. 7 of http://www.paulroark.com/BW-Info/UT14.pdf for the glossy 
paper settings.

The K position is Eboni, which is not glossy compatible.  The midtone 
inks are.  Glop is in the Y position.

The supplied Photoshop curves should be close enough to linearize 
well with Create ICC-RGB for most matte and glossy papers.  See 
http://www.paulroark.com/BW-
Info/Embedding_Photoshop_Curves_in_ICCs.pdf for information on 
embedding PS curves in ICCs.

Hope this helps.
