The Benefits of Archival Matting and Framing
by Sharon Yamanaka
Whether you're a professional artist or a collector looking towards the future, archival-quality framing is the best way to preserve and display your artwork. Archival framing uses only acid-free materials and takes potential problems into consideration, correcting for them before they occur. It is often just as easily done as conventional framing.
What exactly constitutes archival-quality artwork? For the framing itself, it means that anything done to the artwork doesn't harm it in any way, and is fully reversible. As far as archival artmaking techniques, that's a different story. A lot more things such as time, effort, cost, and forethought (often at the expense of spontaneity) go into both the before: making the art, and the after: displaying the art, than into the actual framing. With that in mind, here is a brief description of the steps involved in archival framing and display.
Gathering the Materials
Archival framing begins by using acid-free materials, acid being one of the primary culprits contributing to the breakdown of paper as well as the fading of pigments. There are two types of acceptable archival papers: acid-free and 100% rag acid-free, with the latter, made from cotton or linen "rags," being the highest quality.
Set up your Workspace
Work in a well lit area, preferably daylight. Have all your supplies ready, and have a large clean and sturdy surface to work on. Otherwise you may find that the mat cut is incorrect or uneven, the glass may crack or chip, dust may become trapped in the finished piece -- all making the frustration level rise.
Archival Matting Step-by-Step
Archival matting should be strictly functional -- no doubled, colored or contrasting mats -- just a simple, neutral color that provides a border around your artwork and sets it off, both literally and figuratively, from the outside world. If you want your artwork more ornate, instead of playing up the matting, concentrate on the frame.
Use 100% rag, acid-free mat board such as museum board. (Some mat boards are archival quality only on the side touching the artwork. These aren't considered as reliable as the ones made out of 100% rag throughout.) If anything else is used in the matting -- for example a fabric such as watered silk -- linen or other acid-free barrier is placed between the fabric and the artwork.
The Standard Hinged Mat
The hinged mat is used for pictures with margins, bleed images (these go to the ends of the paper), or papers with deckle edges you want exposed.
The artwork is attached to the backing board with hinges made of paper tape or handmade Japanese paper, which is thin, flexible and has long sturdy fibers. Two rules should be considered when making the hinges. First, use as few hinges as possible, while still providing good support for the artwork. Second, the hinge should always be weaker than the paper to which it is applied, so that under stress the hinge will give way instead of the art.
Never tape artwork directly to a mat or backing board. Even the group of tapes labeled archival are too strong and inflexible to be used directly on artwork. Although the adhesives on these tapes are initially water soluble, they become insoluble over time, requiring the use of a stronger solvent to remove them.
Making The Hinges
The classic hinge is made with two Japanese paper rectangles, typically torn from Mulberry paper or similar lightweight paper and adhered with wheat paste. Lineco's Hayak Gummed Japanese Hinging Paper greatly simplifies the process.
Position the artwork as desired behind the window of a prepared, closed mat. Then open the mat window and make light pencil marks on the backing board around the two upper corners of the art work.
For a V-Hinge, invert the art work on its upper edge, face down, so the two upper corners rest just above the pencil marks.
Place the hinge pieces on a clean blotter and moisten the adhesive thoroughly. Wait for the adhesive to absorb water and get sticky.
Attach 1/4" of the hinge to the back of the art work and the remainder to the backing board, following either the T-Hinge or V-Hinge diagram.
Place the reinforcing strips on a blotter and moisten the adhesive. Carefully center a strip over the portion of the hinge which is attached to the backing board. The hinges should not be visible when the mat window is closed.
Check the fit, then let hinges dry before closing the mat window.
Use standard foam board behind the backing board to support the matted work in the frame. Or hinge your artwork directly to acid-free foam board which works as both backing board and filler.
