Backing A semi-hard backing is placed behind the art in a frame to keep the artwork safe and prevent warping. The backing is generally a piece of foam board cut to size, and is available in white, black or acid-free (archival). The glazier points or tabs inserted into the back of the frame to keep the artwork in place will press against the backing.
