I used to frame all my cels at one time (several 
years ago).  I took great care with archival 
materials and UV-resistant glass, and hung the 
cels in an alcove of a darkly lit room where they 
were exposed to no sunlight and little or no 
artificial light (and *no* fluorescent light).  It 
was nice to have the entire collection up on 
display, and it definitely was a conversation 
piece.  However, after a few months, I noticed 
some browning of the trace lines; and after a 
year, a lot of lines were completely faded.

Of course, we're talking about Toei cels here 
(which are notorious for cheap ink and line 
fading), but I have noticed that the cels kept in 
my cel books are much better preserved.  This was 
a noticeable difference, so now I only keep two or 
three cels up and the rest (including the most 
valuable favorites of my collection) tucked away 
in cel books.

Has anyone else with experience in framing had the 
same problems?  I don't know if it's only Toei 
cels but I would be afraid to take the chance!
