Digital BW, The Print

Hey guys;

I hate yo be the one to say 'the emperor wears no clothes' but the 
point needs to be made more bluntly. The 70+ 100+ years ratings for 
most of these inks are bunk. First of all, for those of you who 
missed it, or can't read between the lines, Wilhelm revamped his 
entire testing method because his tests assumed a linear fade rate, 
which is not correct, and which you can assume to mean in real 
terms, "oops-I think I screwed up". More important, what do you 
consider to be acceptable change? Maybe they won't fade noticeably 
in say 10-20 years if they're displayed properly, but I promise you 
they will get warmer, noticeably warmer, within a couple of years if 
framed, and a couple of months if left out exposed even to normal 
room conditions unprotected. Don't believe me? Test it. Tape a 
couple of prints up  somewhere in normal room light, with a mix of 
tungsten, daylight and fluorescent, (real world conditions guys) put 
a duplicate set in a box, and check them against each other every 
couple weeks.

The bottom line is these projections are good only as relative 
comparisons, and even then, comparing the VM, for instance with the 
dye inks assumes that Epson's and Wilhelm's numbers for the dye inks 
are meaningful. What do you think? Do you trust Epson's claims after 
the orange-shift debacle? I don't. I think if you sell digital 
prints right now at this point in the technology, you need to be 
prepared to replace them at some point in the not too distant future-
and hopefully, at that point we'll have truly archival solutions.

Sorry to be a party-pooper.
