This is very easy to use, and I played with it last night. I did like
the results, but started scratching my head when I wondered how to
warm up the print or cool it down. Where I am a little confused is how
to do this and control each aspect of tone properly.

According to my thinking, if I wanted to "cool" the b&w tone, would I
raise the "Cyan" slider on the epson driver up to achieve this? To
warm it up, do I raise the magenta slider up? What about the yellow?
On matte paper I would think the yellow (glop) would ruin the print.

My other confusion is to how the yellow channel works. I know in the
yellow position there is GLOP. I am aware that I use Ultra Premium
Pres Matte paper at all time (or watercolor), but how do I tell the
driver to use glop/yellow? How is this controlled? I know you said to
start simple, but if I want to use glossy paper then my thinking is I
need to use the ICC profiles (which I have no issue with). But that
again brings me to the point of using the Photoshop curves. Do I just
apply the curve to the grayscale photo, then click on print with No
color adjustments for a glossy print? Or do I use the ICC profile?

Sometimes I over think things and I maybe doing that here. In my mind
I maybe interpreting this all wrong. I have been printing for a very
long time, so in a color world I understand the workflow perfectly. I
have a calibrated monitor, and use ICC profiles for every paper I own
(had them made).
