Making matte finished from semi-gloss prints?

Never mind... Assuming you are interested in changing the finish, not "preserving" it.
If this is the only copy you have, with no negative, I would not trust it to Krylon. Go to a lab and have it professionally scanned and reprinted on luster or satin paper. That way, you have a digital copy, and a print with the finish that you prefer (?)
exactly what I was thinking. Get a copy first!
