Digital BW, The Print

The reason I've always stayed away from glossy inkjet prints for my own work 
is the fact that they are rc based. I have a closet full of old rc type c and black 
and white prints from 20+ years ago and they have already become brittle 
and dried out. The plastic just seems to have aged badly under average 
storage conditions while fiber prints in the same boxes look like new. And I'm 
not talking about prints that have been subjected to even norml WR type uv 
components.  I know that Cibas tend to hold up better and I don't know why.

Personally I think Wilhelms data about rc prints is overly optimistic. 

I used to use a paper that Epson made called Glossy Paper Photo Weight. It 
was a non-rc glossy paper and it looked very rich and saturated even in the 
reds with CF pigments. It was never condisdered "archival" and I"m not sure 
what the reason for that was. The reason I stopped using it altogether was that 
it scratched so easily in the printer and out of it. I even went to an Epson event 
where they had a bunch of prints hanging up and their Glossy P Photo Weight
prints were scratched too. Too bad because I like what they were onto there - 
fiber glossy prints that didn't look and feel like plastic. It would be nice to have 
something like the old Agfacolor fiber silver paper.
