If I didn't respond to Garry's previous post(s), I think he must not 
be using the only sepia solution I know anything about, MIS's new VM 
Sepia-Neutral inkset to Paul Roark's specs.

In any case, Sepia-Neutral seems to me to work very well in an 1160 
starting with either B & W or RGB.

I would not, however, say that the prints are a "rich golden sepia" 
with any one of the four curves you can download on InkSupply.com. 
But they might be if the curves are adjusted or the yellow slider, 
which I also haven't tried, is used.
