You can do two things that will preserve them.
1. Traditional framing
2. Mount them on dibond with a finish
- A mat is important, direct contack between artwork and glass is bad. This especially applies to glossy works.
- Acid-free materials all they way. Acid-free isn't just acid-free.
- Glass is heavy, epsecially at the size of the Skyrim litho.
- Choosing a white mat for a litho isn't enough, as white isn't just white.
- The process should be reversible, meaning you can get the litho out of the frame without any damage.
It is possible to use a mat without permanently fixing the artwork to a backing board. It can be done with tape or "small corners".
Museum glass has these benefits:
- Low reflection
- Transparency
- UV-protection
- Authentic color rendering
Personally I prefer Dibond with acryllic glass because it completely seals the artwork. In the past I've had bad experiences with framers who left dust under the glass, "gaping" mats etc. And these were all professional...
