Some people may consider mat board a framing accessory that is optional; however, mat board protects your artwork from damage. Mat boards provide a spacing element for your artwork; they keep the surface from coming in contact with the glass or plexiglass covering. Humidity from the climate or from home air conditioning systems will eventually cause artwork to stick to the glazing if they have prolonged contact. Even in drier climates with low humidity, matboards should be installed during the framing process.
All matboards were not created equal. Mat board is available in a variety of sizes, colors and quality. Purchasing quality products within your budget that were designed for your specific art pieces will give you the best result. You can protect your artwork and provide an appropriate background with matboard.
How do I chose a mat boards?
Choosing which matboards are best for your project primarily means evaluating the lignon content. Lignon is a natural acidic component in wood (paper). A high acid content means that the signs of aging will show up sooner. The integrity of the piece can be compromised if it dries out and becomes brittle. You may also notice yellowing.
Archival Quality products are made with 100% pure cotton; these are normally reserved for pieces that require total protection from the aging effects of acids. Old documents, photos and art pieces are mounted using this matboard. The main purpose is function and these are predominantly neutral whites and off-whites. You can expect to pay more for archival quality selections.
Acid-free or conservatory mat boards are almost 100% acid-free. That means they will give you the next best option to archival quality products. Acid-free matboard comes in almost umlimited color choices. The benefit of adding color is that you can add an element of contrast to accentuate your artwork. The background becomes a part of the piece, adding texture and interest.
Regular matboard is the least expensive option. These products are offered in a vast array of colors to compliment your art pieces. The acid content can vary from just a little to having the full natural lignon content. Overtime, leeching acid will age anything with constant contact.
