As with digital prints, it is ideal if posters can remain flat. However, this is often not the case and many posters have been folded, rolled or badly stored and will not lie flat when framed. Having a poster backed is the best way to conserve and flatten the image. This will usually involve pasting it to cotton backed, acid-free, heavy weight paper, often known as linen backing. The poster can also be repaired and restored during this process.
Posters are often framed to the edge – i.e. without mounts – and it is best to separate them from the glass in some way, either with a spacer, slip or a window mount. Customers are advised to conduct their own research into how various mounting methods might affect the value of their poster.
When choosing a frame think about the style, period and feel of the image, as well as what you like and what might suit your interior and/or purpose. Black, white frames and aluminium frames are popular with posters for good reason.
Posters were often produced for short-term advertising purposes. We would advise on the use of UV filtering glass or acrylic to avoid fading inks and yellowing paper. If reflections might be a problem, modern anti-reflection glass can reduce them. Using acrylic will reduce the overall weight of large framing jobs and avoid damage caused by glass breakage.
