Dry mounting is a technique used to attach photographic prints to a mounting board or backing surface using heat. A special adhesive sheet, known as shellac tissue, is placed between the print and the mount, and heat is applied to bond them together securely.
This method provides a flat, stable, and durable mounting solution, commonly used for exhibitions, framing, or archival presentation. While dry mounting offers convenience and a professional finish, care must be taken with delicate or valuable prints, as the heat and adhesive can be difficult to reverse.
