Most of the posters I sell here on my website are archival linen backed. Why do I do this?
Linen backing is the best way to preserve and stabilize your poster and provides a canvas for further restorative work.
Linen backing a poster on canvas requires three elements. Linen, acid-free lining paper and a Wheat starch solution containing an alkali buffer which when all combined together produces a stable - but reversible - acid free environment for mounting a poster.
