I don't think Paul can write Epson driver curves for the 
following setup :-)

The Wasatch RIP is a CMYK rip so I can't address the 6 individual 
channels of the Epson 9000.  With the Ultratone VM inks (Black, 
three greys, two blue toners) I have used the recommended 
distribution for Paul's curves at that time. Now I'm using Black 
+ the medium grey in the Cyan channel, the medium grey + light 
grey in the Magenta channel + the dark blue toner in the Black 
channel. The Yellow head isn't used in this setup but could be 
used for a sepia toner with QTR. Now it is easier to get the CM 
curves control the grey part in total and add the toner with a 
single curve for the Black channel.
