"Dave - One thing I'm curious about is whether or not you've assessed the b/w inkjets you're making with your "new" formula under different kinds of lighting. "
Excellent question. Answer. Hmmm, I've been looking at it under tungsten lighting -- tomorrow I'll take one or two prints outside and walk around with them, and then go into various stores looking at them.
One other interesting (at least to me) item is that according to the Red River longevity tests, you can substantially increase the lifespan with Krylon anti-U.V. spray...
Another interesting note, is that on the Epson site, when they talk about those long archival times, they are talking, I believe, about the fading of the inks, and not the change in the color, i.e. yellowing of the paper, and they are talking about the print being under glass.
I got some print speeds from H. who is using the 2200 to compare to my print speeds with the 1280 and there you have a substantial difference:
2200 doing a 5 x 7 print at 1440 = 4 minutes
2200 doing an an 8 x 11.4 print at 1440, high speed turned off takes 8 minutes 12 seconds.
At 1440 It takes me 15 minutes plus, to do an 8 x 12 on the 1280 (high speed off).
And about 7.5 minutes to do a 5 x 7 (high speed off).
So what you are telling me is that the 2200 is about twice as fast. That is scary.

The prints I've done on the Colorlife and the Red River Glossy paper look BETTER in daylight, that is the blacks look even blacker and the overall look is richer.
