As glass isn’t just glass (Link to Blog Post on Glass) paper isn’t just paper. There are two types of paper used in the majority of custom picture framing. Paper that is Acid free, meaning it has neutral pH level, and cheaper paper or older paper that is wood based and is known to be acidic. This is an important piece of the frame, as the acidity of the paper has a direct impact on the piece of art.
Without proper materials, “mat burn” can occur, looking like brown waves that surface from the outside towards the centre of the photograph, print, artwork, etc. Some art can be restored by a professional restaurateur, however that is dependent on the extremity of the Mat burn and what the original artistic material was (water soluble inks and paints such as watercolour cannot be restored fully.
“Acid-free papers are made using alkaline paper making technology. This means the pH of the pulp that is used to form the paper is above 7 (neutral). The paper is also buffered with an alkaline reserve, such as calcium carbonate, to neutralise acid compounds absorbed from the atmosphere or formed through natural aging.” Quoted from http://www.strathmoreartist.com
Museums Board is the highest quality marital available, in that it is arguably 100% acid free, is cotton. Paper made out of 100% cotton finer will be the best buy for your custom picture frame. It will be consistent over the long term, and although it is more expensive, it is relatively worth it when you consider the damage that could potentially done to your art print.
Second to Museums Board is Museums Mat or Rag Mat. This is made out of a combination of cotton and wood pulp, making it less expensive but still providing the archival & conservation standards excepted.
Third is conservation or archival mat boards that are made out of 100% wood pulp. Followed up by material that is lined with acid free material but has an alternative material for its core. This can be problematic long term because the although the surfaces are acid free, the core can leach out the acid from the side and over time potentially impact the art.
Frameworks uses acid free archival materials in all its custom framing, from paper to the mounting tape that is used to mount the image. Don’t forget to take a look at our blog on taking care of your frame, to help enhance the longevity of the materials used to make the frame. Improper hanging locations could cause damage to your art & picture frame.
