LINENBACKING OF YOUR POSTERS
1. Why put a poster on linen?
An old poster is originally rolled up or held flat. An original old poster should be preserved as well as possible in time and be easily framed.
www.posterissim.com brings to each poster a long, delicate and expensive paper conservation treatment called "linenbacking". The linenbacking protects the poster from possible damage and gives the paper a structure that gives it an optimal hold in its frame.
www.posterissim.com calls on the best specialists in this particular technique, whose know-how and experience is recognised by amateurs and collectors all over the world.
2. The technique of linenbacking
The posters are first dry-dusted with gum powder and a brush. Then they are washed with clear water in large basins to refresh the colours and remove paper tension.
The still wet poster is applied to a linen or cotton canvas (Canvas) using a starch solution. A sheet of acid-free paper (Canson) is placed in between. The poster is thus kept at a neutral ph and acid-free to stabilize its colours and protect it from oxidation (yellowing of the paper). A drying time in a dust-free environment of 1 to 2 weeks is necessary depending on the size and type of paper.
A canvas margin of 3 to 5 cm is kept to protect the perimeter of the poster.
All our linenbackings are made with neutral materials that stabilize the acidity of the poster. We use noble techniques that are totally reversible.
Without the application of this technique, the poster, even if it is not damaged, may curl within its frame, thus undermining its artistic qualities and altering its appreciation.
For all these reasons, www.posterissim.com sells mostly, unless otherwise specified, linenbacked original posters.
The folded or rolled posters, purchased on the site www.posterissim.com, can be linenbacked by us (and restored if necessary) on request and after estimate.
www.posterissim.com does not offer a canvas mounting and/or restoration service for posters that do not come from the www.posterissim.com website.
At www.posterissim.com you are thus acquiring a beautiful collector's item that will follow you over time and that you will be proud to exhibit.
