Cels Forum

I have been collecting cels for about a year and have mounted some for my son using matte board as a background or the original background if I was lucky enough to get it.
The question is: My son now wants me to use backgrounds from the actual anime, which I would bring into my computer and then print. Is there a problem doing this? Should I put a clear acetate layer between the cel and the background?
Any help would be a GREAT help.

Thank you,
Walt
