First of all as far as preservation is concerned the frame is redundant. Its primary purpose in one of aesthetics. Therefore the main consideration here is whether or not the frame suits the poster and the place it will be displayed. Nevertheless, it is important that the frame is dry, clean and free from such things as termites or anything that could damage the poster it contains. Whether you are framing your own posters or you want to get a professional to do it for you there are two critical aspects of poster framing that must be understood.click here now
It is critical because it helps you to prevent self inflicted damage, if you are doing it yourself and helps you to evaluate a professional poster framer to see that they would be doing is right. Now obviously there are two sides to a poster: the front and the back. What you put on these two sides are the two critical aspects of poster framing.
Before we go over what is recommended to put on either side of your poster to protect it, at this juncture, let’s quickly mention what you are protecting it from. Due to the fact that posters are made from paper here are five basic evils which need to be considered: moisture, ultra-violet light, acid, termites and damage from wearing and tearing.
To start let’s go over some of the things you should not put on the front. Probably the most obvious is ordinary glass. Not only can it break and damage your poster, but it also acts as a moisture trap and offers no UV protection, leaving your poster open to decaying and fading. Conservation glass does afford UV protection but it is still glass and so can still break and damage your poster. Additionally, it is also very expensive.
Lucite, styrene, low grade acrylics and any other form of plastic sheeting are not recommended. These scratch, turn yellow, offer no UV protection, attract dirt from the air and are not acid-free. Conversely, according to my research high-grade plexiglass is different and is the recommended front covering for your poster. It does not scratch or turn yellow. It does not absorb dirt or grime from the air due its treatment with anti static cream. It does not warp and make your poster look distorted as it’s the same thickness as glass. Additionally it is crystal clear, acid-free and has high levels of UV protection.
The second critical aspect of framing is what you should put on the back of your poster. Regardless of whether your poster is linen backed or not only put acid-free products behind your poster. The reason being that paper will absorb the acid in non acid-free products, such as regular foamcore, leaving you with a yellowing and brittle poster.
Therefore, recommended backing products. are acid-free such as acid-free foamcore and artboard which are readily available in art stores. They may be slightly more expensive but that is outweighted by the far superior protection they give.
