Mat Opening

Mat Opening

Definition: The mat opening is the cut-out window in a mat board through which the artwork is visible. The opening is typically slightly smaller than the actual artwork dimensions, allowing the mat to securely hold the piece in place without slipping. Properly sized mat openings ensure a professional presentation and prevent damage to the artwork.

Key Considerations

• Overlap: The portion of the mat that overlaps the edge of the artwork, usually between 1/8" to 1/4", depending on the frame and mat style.
• Alignment: The opening must be centered and straight to maintain visual balance and prevent artwork from appearing off-center.
• Edge Finish: Cleanly cut edges, often beveled, enhance the appearance and prevent fraying or rough edges, especially with paper or fabric mats.
• Artwork Size: Accurate measurement of the artwork is crucial to determine the mat opening size. Slight reductions in the opening dimension accommodate mounting and overlap.

Techniques and Tools

• Use of mat cutters, either handheld or tabletop, to achieve precise, straight openings.
• Beveled cuts for aesthetic depth and professional presentation.
• Double or decorative openings, such as inner and outer mats, to enhance visual appeal.

Applications

• Framing prints, photographs, certificates, or original artworks.
• Ensuring consistent presentation across multiple pieces in a gallery or collection.
• Providing structural support to delicate or unmounted works.
