Dry Mount: This is where the poster is bonded to a substrate like polyboard, kappa-board, di-bond or aluminum. This is usually permanent and should not be carried out on anything valuable and / or irreplaceable. A window mount can be used to keep the glass away from the artwork, preventing any wrinkling. Here at Soho Frames we also specialise in mounting and can answer any question you might have about the process.
2. Linen-backing: This is often used on vintage posters to stabilise them and ensure they’re suitable for framing. Linen-backing only works on real paper which is why it is not used on modern (post 1980 onwards approx) posters made of a mixture of paper and plastics. This technique is carried out by an expert in the field
3. Japanese paper: This method is used to stabilise modern film posters as well as other artworks. Some framers “iron out” existing issues including wrinkles and defects with Japanese paper. The process can be reversed if necessary though, and is always conducted by a conservator.
4. Insulation: Insulating a frame back with a 6mm MDF panel for example, can protect the artwork when hung on a cold wall.
5. Heat dispersion: Radiators and heat sources can cause wrinkling. A simple solution is to attach a shelf above the heat source to shield the frame from any rising warm air.
