This is the claim they make on their site:
<snip>
Furthermore, prints made with Lysonic SG ink sets will exhibit superior
light fading resistance, similar to that which can be obtained with
high-stability zero-gamut monochrome ink sets.
<end snip>
As far as I can tell they present no actual longevity data for this ink
set...but judging by the longevity data that they do present (and assuming
that these inks are made from the same technology--which I realize is a big
assumption..but they don't tell us otherwise)...they place themselves in the
"1270 class" with respect to longevity. That makes their claim seem
ridiculous...unless by zero-gamut monochrome ink sets...they only mean their
own.
For me, a huge problem with any dye based ink set is the incredible
variability in fade across papers. In my testing, pigment based sets are
much more stable across papers.
