[Openicc] what setting can I use in Gutenprint to get the largest and/or best possible gamut profile?

Genltemen.

I may be out of line with your discussions about custom .icc profiling  
and Gutenprint, but here goes.

I have been creating custom .icc profiles with Gutenprint, the Epson  
Pro 9600 with matte black ink, and Fuji Hunt canvas, as well as with  
HU's German Etching.

My question is what setting can I use in Gutenprint to get the largest  
and/or best possible gamut profile?

I already use ultra photo, 4 pass, eventone, uncorrected, 720 dpi,  
best, watercolor paper-radiant white, adjust dot size, keep print same  
size....don't remember what else.

What I am finding is the custom .icc profiles I create with the plain  
simple Epson driver, have a larger gamut than the same printer/ink/ 
substrate combination with Gutenprint.   I am not complaining, just  
wondering how I can do better with the Gutenprint settings.

I view the profile in ColorThink.

I am not a color scientist.  I might say I am software compromised!     
My goal is to provide the very finest possible CM prints from the 9600.

I use OS 10.4.11 on a G5 tower as well as 10.5.3 on a MBP.    Hardware  
is i1 Pro, and software is i1 Match.

Thank you in advance.
