Digital BW, The Print

I guess I made the original post some time ago about HM  
photorag 308 turning yellow. Here's what I can add today:

A dozen matted shrink-wrapped prints on HM photorag 308 were 
just returned to me today that were displayed in the store area of 
a gallery for  2 months. The paper base looks just as white as 
when I printed them.

Prints that I have at home unprotected still turn yellow quite 
rapidly. And they do not get any direct sun.

I'm thinking I have a local environment that is doing something 
here...

Also, the fact that protected (shrink-wrap or glassed) prints don't 
show the yellowing suggests that it is not UV related. I have not 
done a direct sun test so I haven't seen any "bleaching".

Also, also, I sent samples of the yellowed photorag to 
Hahnemuhle and they are apparently doing some tests at their 
lab in Germany.

If anyone's interested, I'll let the group know what I hear from 
them. They said they'd let me know in the next couple of weeks.

I am relieved that they appear to hold up well when under glass.
