This archival, museum quality mounting and matting board is a must for the highest level of photographic professionalism in all your presentations. Rigid 4-ply thickness adds support and durability, yet cuts very easily. 100% acid-and lignin-free, buffered to maintain a beneficial pH of 8.5 - 9.5. (Note: Buffered mat boards should not be used for Cibachromes and Ilfochromes.)
Bright White: Recommended for matting and mounting black & white photographs.
Natural White: Recommended for matting and mounting color and sepia toned prints due to its softer tone.
