Tom,

This PDF is an add for Mediastreet's Generations and Mark hasn't
been very accurate on the ink data.

I'm using the same ink but I have some reservations on
Generations being more fadeproof than Ultrachrome, Wilhelm's
testing has changed over the years (after the Epson dye ink
affair mainly) and I wonder how well Generations Black + Yellow +
Light Magenta will withstand the test now. Mediastreet had some
luck in having the first pigment ink with a good gamut tested
quite early by Wilhelm and just dye or small gamut pigment inks
as the competition then.

Quite soon after that Epson introduced the 9500 printer with the
Encapsulated Pigment inks called Archival inks, Their fade
resistance is a lot better than Generations. The gamut probably
less and they have some other problems. Mark writes that the
encapsulation breaks open on hitting the paper, I don't believe
it is the case and I have not seen that explanation anywhere
before (there is a dye ink developed now that will use that
method though, reactive dye ink in micro capsules, another
comapny).

After that Epson introduced Dura Brite pigment inks and the new
more fade proof dyes for the 1270/1290/10000 etc.
Dura Brite (not Bright) pigment inks are used in the Epson C
series printers and not in the 1270 as Mark writes, and the
orange plague problem was with the Epson 1270/1290/870 etc dye
inks and not with Dura Brite.

Ultrachrome (not Ultrabright as Mark writes) inks were the last
pigment inks introduced by Epson.



Could be that the rest of the article was written with a lot of
knowledge but this part wasn't. I'm not that familiar with the
other items so I can't judge them as easily but to me this isn't
a 'must read' anymore.
