RE: [Digital BW] Epson K3 Inkset Permanence Rating

The Note on the right of the introduction of the B&W section says: "The
Display Permanence Ratings given here are based on long-term testing with
the previous generation of UltraChrome inks."

So, we have no specific new B&W display life information.

The WIR note continues: "WIR testing to date with UltraChrome K3 inks
indicates that significant increases in Display Permanence Ratings for
black-and-white prints can be expected because the three-level, high-stable
carbon pigment based black inks in the UltraChrome K3 inkset largely replace
the ... color inks ..."

The introduction also notes, "The last of the Iris Graphics continuous flow,
dye-based inkjet printers originally used by Nash Editions was retired in
December 2004."

It all makes me wonder if Epson may be re-thinking its "Giclee" marketing
and predominantly "proprietary dyes and pigments" Material Safety Data Sheet
description of their black inks.  

I hope someone who buys a 2400 will supply me with a test strip to test
against the MIS UT inks as soon as possible.  That should be interesting.

Meanwhile I see Kodak has yet another new top management person. Good luck.
It's going to be hard to watch the Titanic attempt to steer away from the
iceberg with its way too small rudder.
