23x35 Antique Blue Custom Mat for 19x31 Opening - Classic Museum Look

In this review the 23x35 Antique Blue / Dutch Blue Custom Mat is evaluated for framers, photographers, and hobbyists who need a precise, acid-free mat for a 19x31 photo. The bottom line: this mat delivers a professional, classic presentation because it uses standard 4 ply construction and lignin-free, pH-neutral board that fits a 23x35 frame while offering an actual opening size cut to 18.75x30.75. It is a simple, reliable mat for display work where color accuracy and clean fit matter.

Key Features

• Standard 4 ply construction: Provides the thickness and rigidity expected by custom framing shops so the mat sits flat and stable in a 23x35 frame.
• Lignin-free, pH-neutral material: Protects photographs and prints from acid deterioration over time for longer archival life.
• Fits 19x31 photos: Sized to accommodate a 19x31 photo with the actual opening precisely cut to 18.75x30.75 for a snug, professional presentation.
• Color: Antique Blue / Dutch Blue: Offers a classic, muted blue tone that adds depth without overpowering the artwork or photograph.
• Custom openings available: The seller will produce alternate opening sizes on request, which is useful for irregular or custom prints.

Who It's For

The mat is best for professional framers, gallery exhibitors, and home decorators who need an archival-grade mat that fits a standard 23x35 frame and presents a 19x31 photo cleanly. It will appeal to anyone who values accurate cuts and color fidelity in a pre-cut mat.

It is less suited to buyers who need a frame included or who require an unconventional board thickness or material type not described here. If a pre-mounted frame or non-standard substrate is required, shoppers should look elsewhere.

Pros & Cons
