How can I protect my works on paper from light damage? Even though your artwork may be framed under UV filtering acrylic sheeting, the intensity of the light and duration of exposure is a concern. Try to avoid direct and excessive daylight. Close window curtains or drape the artwork when possible. Windows can also be covered with a film or a screen that will lower light intensity and ultraviolet rays. If possible take down the artwork periodically and exchange it with another piece, allowing the work to "rest" in storage.

Glazing can be either glass or acrylic. Only glass should be used with any friable media such as unfixed pastels, charcoals, or graphite, never acrylic as it can damage the work by attracting these materials. There are many brands of acrylic glazing to choose from; one with an ultraviolet filter is recommended. The frame and the mat should be deep enough to prevent the artwork from touching the glazing. A stiff backboard behind the mat protects and supports the matted artwork. It is best to use non-acidic boards. A dust seal with paper or tape is also recommended. What damage results from using poor quality mat board? Avoid mat boards containing wood pulp which causes "matburn"--a darkening of the paper under the mat or at the bevel cut of the window mat.
