Gary... bottom line is, as you know, 
your printer prints in CcMmYK.  It's got 
two extra inks (light cyan, light magenta)
but in most other regards, it's a CMYK 
machine.

Epson has nicely hidden that from us in
their driver software.  There's a built-in
color-separation engine (RGB -> CMYK) that
just can't be worked around.

Unless, that is, you have a CMYK RIP, or
Pressready, or the R9 Plugin.  For ultimate
control freaks, RGB-space is just not 
good enough.

It all has to do with the "black curve" and
how much total ink is delivered to the paper.
When you work in CMYK space, you can control
these things.  In RGB space, it's quite a bit
more difficult.

All this becomes important the more you get
away from "conventional" usage of the printer.
If all you're ever going to do is print 
decent, "normal" color prints on Epson inks
and Epson paper, you really don't need to
mess with CMYK.  OTOH, if you're a mad-
scientist type like Dan C., mixing your
own inks and sizing your own paper, it's
a valuable tool.

If your work will be printed on on offset
press, then you *must* pay attention
to its composition in CMYK space.  This is
in fact what PressReady is designed for.
