OBAs and UV filtration

the only thing I'm concerned and I don't really know how it can effect the paper and ink over time is

OBA Content: Yes


somebody more experienced can tell me if is something to be concerned about?

OBAs fade and turn yellow over time if exposed to UV light. This is not a problem if your photo is not exposed to either sunlight (directly or indirectly) or to fluorescent light or is framed behind UV blocking glass. The common LED light used today has little if any UV light.

I think we need to point out here that if you print on a paper containing a substantial amount of OBAs and then display the print behind glass that substantially filters out UV light, then the paper will not look the same once displayed as it looked out of the printer. AFAIK there is no way to have it both ways: the paper is designed to look a certain way by being exposed to UV light and then using that to affect the visible appearance. If you prevent it from getting that exposure, then it won't look like it was designed to look.
