Epson LUT print technology

I have previously written that the instructions for Epson Sure Color
P-800 recommend that with Photoshoop CS3 or later, All LR and also PS
Elements 6 or later - the printer should manage colours. I have
confirmed that with CC LR having the printer manage colors gives a
vastly superior result when using Epson Premium Glossy paper. I may
now have discovered why this should be.

Epson in conjunction with the Rochester Institute of Technology have
taken color management to new levels. The problem appears to be that
while with 8 colors there are a zillion ways to blend them to achieve
a particular color there is only one best way. Apparently the
mathematics are complicated but are vastly simplified by use of a
massive Look Up Table (LUT). Presumably all this is built into the
driver.

Down loading the driver results in about a dozen ICC paper profiles
being installed in Windows\System32\spool\drivers\color but these can
only be used with LR and the like. They cannot be loaded into the
driver which reports that they are incompatible (or some such).

My suspicion is that the LUT is available only when the printer
manages colors. I don't know why this should be but that's what it
seems to be. Apparently Epson's larger printers have been using this
for a while and it is now moving to smaller models.

http://factor.bg/epson/SP9900/Maximu...r_fidelity.pdf is a blurb
which doesn't really tell you much.

https://www.youtube.com/watch?v=egLCg3GiXIE is also a blurb but gives
more information.

Whatever the explanation I am banging my head on the wall waiting with
great impatience for a version of the driver which incorporates the
profile for Archival Matte paper.
