If you plan to display your print away from direct sunlight and finger touches, this option should be sufficient.
Protect your photos from UV light, dust and fingerprints, greatly expanding the lifespan of your prints. It also helps reduce bronzing and gives you a more uniform surface. Coating does introduce some tiny spots to the print that become visible under sideways light.
On top of UV protection, multiple layers of coats will shield your prints from accidental splashes of water or temporary exposure to moisture in high humidity environments. Please note that only the print side is protected.
