Linen Backing
Linen Backing. The process of mounting a poster onto acid free paper and cotton canvas. Posterfix Linen Backing is "archival" and enhances the health and longevity of the poster. It is especially helpful for old, brittle and deteriorating posters. It flattens folds and creases, and provides a base for further restoration, and finally framing or storage.
The procedure includes mixing calcium carbonate into the paste to help create an Acid-Buffer (different from “de-acidification”). Using acid neutralized wheat or rice paste- the poster is glued to the paper, and the paper to the stretched canvas. While Poster, Paper and Canvas are still wet, we are able to do further surface cleaning and flattening. The drying process is 4 to 6 days, depending on the atmospheric conditions (humidity) of the environment. Our most popular form of archival mounting is Linen Backing and is also referred to as “Canvas Backing”, “Canvas Mounting” and “Cotton Mounting”. To “Linen Back” has become the popular term even though Cotton is the most used material in the world. This process is a direct descendant of Rice paper backing and Silk backing traditionally done in the Far Eastern countries such as China, Japan and Korea. The French adapted and developed these techniques in the late 19th century for Poster Collecting.
Some of the benefits of today’s Linen Backing include flattening the folds, sealing tears, and providing a base for restoration if needed. It is also good for framing or other display techniques.
