Whitest Rag mat?

What's the whitest Rag mat?

For white photos...I try to get the photographer to print/provide a large white area to use as a mat. Then mount to Kooltac (or equivalent) mat board weight. then cut the mounted "white photo" as a mat...
otherwise, fabrics are your top whites

Probably Digital white from Bainbridge. It has optical brighteners, so it isn't truly archival if that is a concern.

We use a lot of Rising Polar White. Consistent color and quality every time.

Digital White gets pretty yellow over time as the optical brighteners lose their effectiveness, fyi
