Each print is different and each may well need to be framed differently. If you stick with top notch materials and keep it simple you will soon find it easier to frame different style images to emphasize the print, not the presentation. A well framed print should stand out while the surround receded into the background while not disappearing. A well done print presentation will keep your vision on the single print and not hasten your looking at the next one. It is a fine balance.
Good materials make the effort easier.
I use Bainbridge AlphaRag Artcare board for most of my frame work. It has a micropore trapping system built in that helps protect the print from atmospheric pollution as well as the outgassing from the prints themselves. It does NOT protect the print from the damaging UV light rays. In dark storage the Artcare mats actively protect the prints. If you want UV protection you will need to go with a high quality UV protective glass such as the coated museum glass that is available.
