A pictureliner is a term mostly used in the art world to describe a protective backing material or liner that is placed behind a piece of artwork, usually a painting, within a picture frame. It serves multiple functions, primarily to support and protect the artwork from various external factors such as humidity, dust, and insects, ensuring its longevity and preservation.
Typically made of archival materials like acid-free paper or fabric, a pictureliner is custom-fitted to the dimensions of the artwork. It is secured to the back of the frame or directly to the stretcher bars, encapsulating the painting and creating a barrier between it and the frame. This backing serves to prevent the artwork from coming into contact with the frame's wood, metal, or any other potentially harmful materials.
The pictureliner also helps to maintain the painting's stability and prevent any flexing or sagging that might occur due to changes in environmental conditions. By providing additional support, the liner acts as a stabilizing element, thereby reducing the risk of damage like cracking or warping.
Moreover, a pictureliner can effectively absorb and dissipate any excess moisture that might accumulate behind the artwork. This is particularly important in preventing the growth of mold or mildew which can deteriorate the painting's surface.
In summary, a pictureliner functions as a protective and stabilizing layer between a painting and its frame, safeguarding the artwork from potential damage and preserving its quality and longevity.
