Digital BW, The Print

John, this may be "all you have," but for me, it's a lot. You answered two 
questions that I have been concerned about: how to handle dust on white, and I 
know that all poster, mats, etc will eventally warp. At least I thought so.
Thanks, Craig

Some good info in here. I am not up on NMs Ernst and didn't actually go into 
that article. What my glass reps have told me ( I am a custom framer, gallery 
and photographer- http://saddletreegallery.com/ ) since I carry mostly Tru View 
I will reference that: 

Premium Clear is "regular" glass and filters about 35% of UVA UVB from hitting 
your artwork. 


Conservation Clear is available in regular and Non Glare finishes and filters at 
about 98.5 % rate. 


Museum Glass is around 99 percent. 

Jimbo - acrylic also comes in the "museum" coatings, and is known as Optium. It 
is easier to clean than the glass but nearly twice as expensive. Full sheets at 
wholesale are over a $1,000. So jimbo is right be prepared for sticker shock if 
you are looking into that. 


One misnomer is that Museum coating eliminate reflections. They do not. They 
minimize to the point on not being easily seen. I have framed hundreds of pieces 
with museum glass and Optium. To prevent customer disappointment, I have a 
framed sample that I encourage them to take home and hang to show how well it 
works, but also to show that it will reflect some and to make sure that is 
acceptable. 


Rule of thumb in framing is paper goes under glass. I have been using a Bienfang 
UV rated laminating product on a lot of my own photography and people really 
seem to like not having to deal with glass and reflections. 


If you have your print coated with ArtShield or similar, I would think the 
degradation and dirtying of the mat would be as big of issue as the print. If I 
have coated a print I don't have any trouble dusting it. And it will need it. 
Once a white mat has dust on it, it's almost impossible to clean. Almost all 
mats that I have seen that aren't under glass will warp over time. Less so in 
the 8 ply. 


That's all I have.
