Digital BW, The Print

OK' this one is REALLY informal, and lousy science, but interesting 
nonetheless_

I put up two prints, one w/ Museum K (BO)on EEM, and another w/ 
Ultratones (VM 4.3) on Hannemuhle William Turner. Location was the 
BACK WALL of my Florida room. I emphasize that because at the back 
they get NO direct sunlight, just moderately strong ambient. Heat 
fluctuates between 80 and 95 deg.F. depending on wether the ac is 
on, and the humidity is probably never under 75%, so it's still a 
torture test.

One month later: the Museum K shows a slight but noticeable magenta 
color shift that becomes very obvious when i lift the covered 
section to compare. Much more disturbing: the BORDER areas that have 
neither ink or base liquid on them have turned yellow. So much for 
EEM being enhanced.

The VM 4.3 on Willie Turner OTOH shows no visible change. Not only 
did it it not fade or color shift, but I think (don't have a 
densitometer to verify) the exposed areas have actually GAINED a bit 
in DMAX. Paul Roark reported a similar result for the Epson matte K, 
does this mean the two inks are actually one and the same?
