The Epson Gloss Optimizer for the R1800 & R800 is a clear ink that may 
have clear acrylic particles in it but is, by weight and not counting 
the water, mostly glycerol.  It basically fills in between the color 
pigments so that bare paper does not show through, helping to eliminate 
gloss differential and some of the other reflective artifacts that have 
plagued glossy digital printing.

The MIS Gloss Optimizer is essentially the glossy base with no 
pigments.  It can be used the same way as the Epson version, but we are 
also using it as a clear coat.  A post-printing spray like Premier Art 
Print Shield has been the best way to eliminate the glossy artifacts 
and protect glossy prints, but a number of us are experimenting with 
Gloss Optimizer (often referred to as "GO" or "Glop") as a coating for 
glossy prints, running the print through the printer a second time to 
apply an even, clear over coat.  This often increases the dmax and 
eliminates most of the artifacts. At this point I still consider it an 
experimental workflow, but some of the results are very good so far.
