The conversation between acidic and non-acidic materials is a silent one, but it screams to those in the know. Acidic papers and mats are the silent killers of art. Over time, they cause discoloration, brittleness, and irreversible damage. The professional art world operates on a foundation of preservation. By using acid-free, archival materials throughout—from the printing paper to the mounting board—you are speaking the language of conservation. To find out more about the proper way to present
