Not sure this is the right forum for this question, but could not find another more appropriate - will try here first.
I print some photos on my Canon Pixma Pro9500 Mark II. I would like to put a black foamboard on the back of a 13x19 print and would like to display it just like that - no frame with glass 'protecting' the surface of the print. Is there a spray treatment I can apply to avoid damage due to liquid or dust/dirt? I printed on Canon Photo Paper Plus Glossy II paper, so I'd like to keep the gloss of the paper surface.
Please be specific with any recommended spray/other, as I am unfamiliar with this area.
Thanks very much! I need an answer soon. Thank you!
