Inner Mat

Inner Mat

Definition: An inner mat is a secondary mat board placed beneath the top mat in a picture frame setup. Its purpose is to create a visible border or "reveal" that adds depth, visual separation, and contrast between the artwork and the frame. Inner mats can be made from a variety of materials, colors, and textures to complement the artwork or highlight specific design elements.

Design Characteristics

• Reveal Width: The inner mat is typically visible around the edges of the top mat, with widths ranging from a narrow accent line to a broader secondary border.
• Color & Texture: Inner mats are often chosen to contrast or harmonize with the top mat or artwork, enhancing visual impact.
• Depth & Dimension: Layering multiple mats adds a three-dimensional quality to the framed piece, giving it a more sophisticated presentation.
• Customizable: Inner mats can feature bevels, fillets, or decorative edges for additional detail.

Materials

• Matboard: Acid-free, archival-quality mat boards in various thicknesses and colors are most common.
• Fabric-Covered Mats: Adds texture and a luxurious feel, often used in high-end frames.
• Specialty Paper Mats: Textured, metallic, or handmade papers can be used for artistic effect.

Applications in Framing

• Visual Separation: Helps prevent the artwork from blending into the frame, making it stand out.
• Color Enhancement: The inner mat can pick up accent colors from the artwork or add complementary tones.
• Depth Illusion: Double or multi-mat setups with inner mats create a sense of dimensionality and refinement.
• Highlighting Artwork Features: Inner mats can be used to emphasize specific parts of the image or to coordinate with a fillet or decorative inlay.

Best Practices

• Proportion: Ensure the inner mat's reveal is balanced relative to the top mat and frame size for visual harmony.
• Material Choice: Use archival and acid-free materials to protect the artwork over time.
• Color Selection: Inner mat colors should enhance, not overpower, the artwork.
• Precision Cutting: Accurate cuts and bevels are essential for a professional and seamless appearance.
