What is conservation framing?
Conservation framing (also known as preservation framing) is the professional application of knowledge, materials and techniques to the framing of valuable artwork such that the artwork is not permanently altered in any way. In short, it is doing everything possible to ensure that a piece of artwork removed from the frame at a later date will not show any evidence of having been framed, thus preserving its long-term value.
However, complete conservation treatment of a particular piece of art is not always appropriate, desired or affordable. Therefore, there are always degrees of appropriate conservation to be applied in any situation. For example, a wrinkled and torn old poster, primarily of sentimental value, might best be dry mounted for its best appearance, but acid free mats and U.V. protective glazing applied to reduce the likelihood of continued deterioration. The designer will advise you of the options and possible consequences, but the degree of conservation is always your choice.
