4.3 Presentation, Matting, Framing & Exhibition of Artwork

The Importance of Professional Presentation

The creation of an artwork is only the first phase of its lifecycle; how it is presented, protected, and exhibited is equally critical. Professional presentation serves a dual purpose: it aesthetically isolates and enhances the artwork, allowing the viewer to engage with it without distraction, and it physically protects the piece from environmental degradation. For two-dimensional works on paper—such as drawings, photographs, and prints—proper matting and framing using archival materials is an absolute necessity to ensure the longevity and historical preservation of the artwork.

Archival Materials and Conservation Framing

The central tenet of conservation framing (or archival framing) is reversibility. Any mounting or matting technique applied to an artwork must be completely reversible without causing any damage or alteration to the original piece.

Acid-Free Mats and Backing Boards

Standard paper and cardboard products are manufactured from wood pulp, which contains high levels of lignin. Over time, lignin breaks down and releases acidic compounds. If an artwork is placed in contact with standard wood-pulp mat board, this acid will migrate into the artwork, causing a phenomenon known as acid burn. This results in irreversible yellowing, embrittlement, and scorch-like marks around the edges of the paper.

To prevent this, artists and conservators use acid-free mats. These fall into two main categories:

• Alpha-Cellulose Boards: Wood pulp boards that have been chemically treated to remove lignin and buffered with calcium carbonate to maintain a neutral or slightly alkaline pH.
• 100% Cotton Rag Boards: Made entirely from cotton fibers, these naturally contain no lignin and are considered the gold standard for museum-quality conservation framing.

Hinge Mounting Techniques

Artwork should never be permanently glued or taped to a backing board. Instead, conservation framing employs hinge mounting. This involves attaching the artwork to the acid-free backing board using small tabs (hinges) of Japanese paper adhered with reversible wheat starch paste.

The hinges are typically applied only to the top edge of the artwork, allowing the paper to expand and contract naturally with changes in humidity. If the artwork is restricted on all four sides, fluctuating humidity will cause the paper to buckle or tear. Pressure-sensitive tapes (like masking tape or scotch tape) must never be used, as their synthetic adhesives will stain the artwork and become permanently crusty over time.

Glazing: Protecting from the Environment

Glazing refers to the transparent material placed in front of the artwork within the frame. Its primary functions are to protect the art from physical damage, dust, pollution, and harmful ultraviolet (UV) light. The glazing should never directly touch the surface of the artwork; the window mat provides the necessary airspace to prevent condensation and mold growth, or the adhesion of the medium to the glass.

Glass vs. Acrylic

Artists typically choose between two types of glazing:

• Silica Glass: Traditional framing glass is scratch-resistant and relatively inexpensive. However, it is heavy, fragile, and inherently dangerous if shattered, making it unsuitable for large artworks or pieces being shipped.
• Acrylic (Plexiglass): Acrylic is shatter-resistant and significantly lighter than glass, making it the preferred choice for large works and traveling exhibitions. Its main drawback is that it scratches easily and holds a static charge, which can pull loose media (like soft pastels or charcoal) off the paper.

UV Protection

Both glass and acrylic can be treated with UV-filtering coatings. Archival glazing filters out at least 99% of harmful UV radiation. UV light is highly destructive to art; it fades pigments (particularly organic dyes and watercolors), yellows paper, and accelerates the breakdown of binders.

Principles of Exhibition Design

When artworks are brought together in a gallery or museum setting, the exhibition design dramatically influences the viewer's interpretation and experience.

Lighting

Lighting is the most critical element of exhibition design.

• Intensity: Delicate works on paper, textiles, and watercolors are highly light-sensitive and should be displayed under low illumination (typically around 50 lux). Oil paintings and sculptures can withstand much higher light levels.
• Color Temperature: The color of the light impacts the perception of the artwork. Warm light (around 3000K) enhances reds and yellows, while cool light (around 5000K) emphasizes blues and greens. Museums often aim for daylight-balanced lighting to present colors accurately.
• Placement: Track lighting should be angled (typically at a 30-degree angle) to minimize glare on glazed artworks while avoiding the casting of harsh shadows from heavy frames or the viewer's own body.

Spacing and Flow

The physical arrangement of artworks dictates the flow of foot traffic and the narrative of the exhibition. Artworks should generally be hung with their centers at a uniform height—usually around 57 to 60 inches from the floor, representing average human eye level.

Providing adequate "breathing room" between pieces prevents visual clutter and allows the viewer to absorb each work individually. Works grouped closely together (salon-style hanging) force the viewer to look at the relationships between the pieces, whereas widely spaced works (gallery-style) emphasize the solitary importance of each individual object.

Mastering presentation and exhibition techniques guarantees that an artwork is not only visually striking but structurally secured for future generations to appreciate.
