<p>Tim, the fading of the OBA over time will take several years and it just means it will not convert UV-radiation as well. It will just be a possible minor color shift where there is ink, and where there is not, the brightest whites may not be as bright. It may be difficult to notice without doing a side by side comparison. In the case of your own prints, it is a non issue since your digital copies will not be fading. It is generally more of an issue for someone that is paying good money for a fine-art print where they cant just reprint it, but might want to pass it on to their children. For most the issue I am bringing up is not a big deal since most are not concerned about archival framing. I did have a customer that accidentally bought UV-filter acrylic and was disappointed at the effect it had on his print which is what caused me to investigate this issue.<br>
<br />Frame shops are often held liable for the print degrading over time so they will tend towards archival framing which means UV filter glass or acrylic. In the case of framing something like a newspaper article which is guaranteed to fade in a short amount of time they will suggest photographing the news paper article and framing the copy while keeping the original in the dark.</p>
