We have just greatly expanded our conservation rag mat board line with new colors and types:

8-Ply Alphagag Mat Board – 11 new colors
4-Ply Alpharag Mat Baord – 25 new colors
2-Ply Alpharag Mounting Board – 2 new colors

The 2-Ply can be used for mounting portfolio prints to, buffer layer over a non rag picture frame backing, or for color matching when float mounting a print where part of the mounting board is exposed.

Bainbridge Artcare Alpharag mat board is some of the best protection you can buy for framing your prints:
100% cotton rag
Solid color throughout including the bevel
Acid free and Lignin free
Bleed and fade resistant
Buffered to maintain alphaline pH
Passes Photogarphic Activity Test
Meets and exceeds ANSI/NISO A39.48-1992 Regulations for paper permanence

Cheers,
Mark
