After some reading, it's a waste to simply frame up using traditional backing methods. Here's are my notes .resulting in this,
Front
- Pick high-grade plexiglass with UV protection, 1/8" thick, crystal clear, non-glare,
- Lighter
- Glass has issues (moisture entrapment, likely no UV protection, poster can stick despite spacers or mat)
- Conservation Glass is better, but can break and expensive
- Do not use ammonia based cleaner
- Use especially for bigger posters as it is lighter than glass
- Use a mat to ensure the glass if lifted off the surface (only possible for smaller than 40" x 60" posters)
