Diasec USA - Picture Framing Terms & Glossary

Glossary Of Picture Framing Terms [1]

Diasec Diasec is a registered trademark for a process used for face-mounting prints like photographs on acrylic sheets. The process was invented by Heinz Sovilla-Brulhart in 1969.

Because of the different light penetration and refraction of acrylic compared to normal glass, the colours are more brilliant and the image sharper than compared to standard glass in a picture frame. A Diasec mount is usually of a high gloss finish. Because the print is glued to the acrylic glass, the result is a completely flat mount of the image.

Process

The process aims to mount the print without air bubbles or smears. The image is face mounted and bonded to the acrylic glass with a gel silicone sealant which acts as a glue.

Normally the print is placed on a carrier at the backside. This is usually dibond, a composite plate of aluminium and plastic. Aluminium or other materials are also possible. If the print has to be backlit, translucent materials are necessary.
