A variety of glass and acrylic selections are now available. Regular glass and Plexi-glass are the most cost effective. Optium Acrylic and Museum Glass will provide the ultimate UV protection and museum quality clarity.
There are a number of basic characteristics of framing that will help to maintain the condition of your piece. The glazing (glass or acrylic) should be UV-protective to help prevent damage to your item from ultraviolet light.
*Since UV light rays come from indoor and outdoor light sources, all items on display are vulnerable to the damaging effects of UV light exposure. That’s why it is important to use glass with at least 97% UV protection on all of your custom framing jobs. Conservation framing materials and techniques should be used on sentimental, valuable, limited edition and one-of-a-kind artwork.
Also, use UV protection glass on all works of art you want to protect, especially posters and open edition prints. Posters or open edition prints are more susceptible to UV light damage since the inks, papers and other materials used to create them are more likely to deteriorate than those used in higher end reproductions.
*Without at least 97% UV protection framed pieces will age and fade more rapidly. Indoor and outdoor UV light rays contribute to severe color loss, paper embrittlement and deterioration of framed pieces. These effects are both cumulative and irreversible. The materials that make up the piece, the paper or fabric on which the image is displayed, may become brittle. Photos may appear yellow or stained with ghostly silver deposits rising to the surface. Once damage from light has occurred, it can never be reversed.
