Sorry, perhaps its my misreading...but I thought they said ink set"s".  If
they had simply said:

"can be obtained with our high-stability zero-gamut monochrome ink set".

I wouldn't have had a problem.  As far as I know...and I may be
uninformed...all the other quad inks sets (which by Lyson's definition are
"zero-gamut monochrome inks") are pigment based and have far superior fading
properties.  I think this statement could be easily misleading to people
trying to learn about the relative merits of different BW printing options.

Also, I was looking at the wrong longevity data...my apologies...they claim
that their quad ink set performs much better than 1270 dyes...sorry for the
confusion.  Has anyone validated this claim by window testing...or for that
matter comparing their fade to piezo or MIS FS or VM inks directly?
