Digital BW, The Print

Hi,

I have the R1800 with the Eboni 6 inks installed.
Though I'm using QTR and unsure of the process of using all 6 inks?
I've selected the printer as "Epson Stylus Photo R1800"
Though the printing model i'm unsure what to select here? What reflects the Eboni 6 inks?
All listed for the R1800 is the 
QuadR1800
QuadR1800-3MK
QuadR1800-K7

I've gone through Paul Roark Eboni-1800.pdf but it doesn't state how to utilise the 6 inks in QTR. Unless I'm missing something entirely, which could/usually be the case! :)
 
Thanks
