Before entrusting your cherished artwork, photographs, or documents to just any mat board, consider the superior protection and presentation offered by our 17x22" 4-Ply Conservation Mat Board. Crafted with meticulous attention to archival standards, this pack of 15 pearl white boards is the epitome of durability and high-quality conservation.Our Conservation Mat Board is constructed from alpha-cellulose pulp derived from purified wood fiber, a choice that marries economic efficiency with the stable, long-lasting properties that professionals demand. The use of purified wood pulp paper has a trusted legacy for its safety in contact with paper-based art and photographic materials, ensuring your pieces remain pristine over time.Each board in this 15-pack is acid- and lignin-free, a critical feature for the preservation of your items. The boards are treated with alkaline or neutral sizing, both internally and externally, and do not contain any alum in the manufacturing process. This careful preparation results in a product that resists the destructive effects of acid migration and environmental pollutants, maintaining a stable pH level to prevent the mat board from becoming more acidic as it ages.Buffered with calcium carbonate to provide a 2-3% alkaline reserve with a pH of 9 +/-0.5, our Conservation Mat Board is designed to offer the utmost protection. The color dyes used are light-fast and non-bleeding, ensuring that the board itself will not degrade or cause harm to your mounted and matted artwork.The 4-ply construction of this board, approximately 1/16" in thickness, provides a sturdy and reliable foundation that is resistant to tearing and warping. The layers of single ply sheets are seamlessly laminated together using an all-natural starch adhesive, further reinforcing the board's integrity.Our Conservation Mat Board passes the rigorous Photographic Activity Test (PAT) according to ISO IT 18916 standards, confirming its safety for use with photographic materials. The lignin content is meticulously tested to have a Kappa number of less than five, indicating a very low likelihood of causing any discoloration or degradation to your treasured pieces.The pearl white hue of our Conservation Mat Board offers a warmer tonality compared to bright white options, akin to Antique White but with a subtler yellow tint. This provides a neutral and inviting background that enhances the visual appeal of your artwork. The board's surface and cutting characteristics are remarkably similar to those made from cotton pulp, offering a lustrous finish that professionals appreciate.Opt for our 17x22" 4-Ply Conservation Mat Board for a blend of professional-grade archival quality and aesthetic appeal, all at a very attractive price point.
