I dont know to much about building boards but I work for a printing company and we have UV printers meaning there are high intensity UV lights on the printer that are used to cure the ink so would asume that this would be a good option as UV light should not affect the print especially once it has got some resign over it.
most of our prints are used outdoors and they last very well.
hah russzim, that is what I was maneuvering to as well. UV print is UV stable, I just was not sure if he had access to a UV printer. Another thing to mention is that you can print UV onto almost any flat substrate. You can even print to fabrics, there are tons of fabrics that we can print on using the UV flatbed, I'm not sure how the resin would react to the fabric or the UV print but I bet it would work just fine.
