ALPHARAG is made from a pure cotton rag pulp and offers one of the highest quality mats available. Alpharag has a solid consistent color throughout and is fade and bleed resistant with color consistency for colors that stay true for the life of your art. Alpharag is strongly recommended for fine art prints, limited editions, valuable documents, photographs, and all other archival matting needs.

Alpharag Artcare protects artwork from pollutant gases and from acid by-products using the Artcare Process. The pure cotton pulp used is acid and lignin free and is buffered to maintain an alkaline PH balance.

Great care has been taken to represent our mat board colors as accurately as possible, however color variance among monitors means that mat colors on your screen may not be exact. Openings in illustration are not representative of actually specified opening size.

We also offer Multiple Window Collage Picture Matting and uncut mat board. If you are looking for uncut mat board you can order Alpharag Museum Solids mat blanks in any of our colors from the drop down menu under standard sizes. The blanks are listed at the bottom of the list and have the outside dimensions only listed and say (BLANKS) in the description rather than window opening size. We offer all our standard sizes from 5x7 up to full sheets of 32x40 and everything in between with custom matting.

If you have any questions about what size mat board you need or sizing your pictures or other artwork, please give our customer service a call or see our online sizing guide to selecting the best size for your framing and matting needs. REDIMAT offers a large selection of photo mat board products in the most popular picture and frames sizes including several harder to find square picture sizes. Using the custom mat board feature found on this material page it is possible to create most any custom mat size and you get the same pricing as our standard sizes when buying in bulk quantities.

All of our AlphaRag mat board is precision cut for perfect craftsmanship with our computerized mat cutters and skilled operators in the USA.
