Digital BW, The Print

> Todd, 

I have seen the stepwedges of Piezotones black ink that were left in a
fade tester
for 100 hours. They faded quite badly. Very sepia.  Do you think it
possible for a wedge made with all the colors would prevent the black
from fading?

I've also seen bad fading with prints made with the epson 2000P and
their "Archival Inks."

So I wouldn't bet the farm on Anybody's claims any more.  As I've
mentioned countless times, I've never seen any fading with any inkset in
the past 4 years, on any good paper, as long as the lighting conditions
were low level, such as you'd find in the 
average home. The brighter the light, the worse they fade. No ink I have
ever tested has gone much more than 3 months in direct sunlight without
fading. I simply refuse to worry about fading any more.
