Hi tfonzart,
When you print the labels, I would suggest using a 30 lb. paper, or a matte presentation paper as opposed to regular printer paper. Both the 30lb and presentation papers are thicker than the regular printing paper and disperse the light from behind the labels better

I would also suggest having the labels printed on a laser printer as opposed to an ink jet as the printing with a laser printer is less prone to U V fading. If you do print using an ink jet printer, you can spray the printed labels with an Inkjet print fixative (Local art supply stores as well as Amazon carry this product). This will seal and protect the printing from u v fading as well as water and fingerprints, etc.
