Overmat

Overmat

Definition: An overmat is a mat board with a cut-out window through which artwork is displayed. It allows the artist or framer to showcase the artwork while concealing edges or borders that are not intended to be visible, providing a polished and professional presentation.

Overview

Overmats serve both functional and aesthetic purposes in framing. They help position the artwork securely, create visual separation between the artwork and the frame, and can enhance depth, color contrast, and overall composition. Overmats are commonly used in single and multi-mat presentations.

Materials and Types

• Ply: Mat boards come in varying thicknesses, such as 4 ply or 8 ply, affecting rigidity and depth.
• Material: Acid-free cotton rag, alpha-cellulose, and museum-quality boards are preferred for archival purposes.
• Styles: Overmats can feature single windows, multiple windows (collage mats), or specialty shapes like ovals or keystones.

Uses

• Frames artwork securely while concealing the edges.
• Adds depth and dimension to the presentation.
• Enhances color contrast between artwork and frame or other mats.
• Provides archival protection by reducing direct contact with frame glazing.

Considerations

• Window size should be slightly smaller than the artwork to allow for proper overlap.
• Thickness of the mat can affect the visual proportion of the artwork to the frame.
• Choice of mat color and texture can influence the perceived tone and mood of the artwork.
