Would just like to know if vacuum packing the 
cels would help maintain its condition. Such as 
line fading and turning soft of the acetate 
paintings.

I've read up an article that says you need to air 
the cels by letting the gas escape if you've 
framed them up. I would just like to ask in what 
way will it harm the cels if you've framed them 
up without letting them aired? I don't understand 
that at all...
