Archival Methods

Archival Methods 4-Ply Black 100% Cotton Museum Board contains 25 boards that measure 4 x 6" each. The board is a high-quality mat board used for many fine print and document projects. Whether for traditional print or digital technology, this board will provide a solid, acid-free backing that is perfect for display purposes. It can also be used for small mat cutting where, for example, a 2-ply board will provide a 1/32" separation between the work and the glazing.  Your best print deserves the best mount possible. Presentation is half the battle and Archival Methods gives you the way to show off your best work. This is quality board designed for archival display. For window mats and mat backing, Archival Methods recommends a thickness of 4-Ply, which creates a 1/16" separation between artwork and glazing and provides a flat, supportive backing.
