Lyson sells the Lysonic ink set, which is a very long life dye set, with some
gamut weaknesses in the reds, and would possibly see some image gamut
improvements from O&G inks (especially the O), the Fotonic medium life dye
inkset (that offers an excellent gamut hardly in need of improvement for
images) and a line of proofing inks (not designed for extended life, but for
widest possible gamut) which would see virtually no advantage to O&G
components in images, only a larger range of difficult spot color matches.

The RIPs from Epson (StylusRIP is the usual name) isn't even a true four
color RIP, insted returning to Epson's RGB screening process. We're talking
about a RIP that costs several times as much as the printer, when we discuss
6 channel and greater RIPs. A ballpark figure of that increase in spot color
matching would be that a good 6 color RIP with a license for the Pantone
values, and a good 6 color profiling system, on a good media could hit 90% of
the Pantone coated colors with CcMmYK, and more like 99% with CMYKOG, with or
without the light c&m inks. But this is not trivial, and would be more
appropriate with a 5500 (an Epson ProLine printer with more supporting RIPS)
than a consumer level 2000p.

Most of them, and all the ones I work with, but as I recall there have been
one or two CMYKOG desktop devices from other companies... anybody recall
names?

Certainly that could use the inksets... OS level drivers can seperate to
CMYKOG, but they can't offer channel control to that or any other non-RGB
space, so a RIP is still a requirement for advanced control of the ink
channels.
