So, does that mean that other patented head configurations, like the Iris for example, are 
incapable of using the high-stability pigment inksets? HP is certainly doing something 
interesting with pigments in their thermal printers to achieve such ratings.

-Apparently one thing that limits the non-Epson desktop printers in this
regard is the viscosity of the inks. The piezo-electric head that Epson has
rather well protected with patents may be the only one that can pump the
high-viscosity base needed to keep high loads of larger particles in
suspension.
