Many years ago (40), I printed a large portrait for a pro who asked me to varnish the print which was printed on Medalist G and I was amazed how beautiful it looked. I also remember lacquering two 16X20 prints with a commercially available flat spray lacquer for another pro who changed his mind after the prints on F (glossy) surface were already dry mounted and he didn't want to spend the money for a matt surface reprint and remount. Well, yesterday, I attended a rosary where the subject of the lacquered portrait was being remembered and lo and behold there was the portrait I had printed all those years ago, on an easel in front of the alter. It was still in the same unglazed frame he selected and it looked exactly the same as the day I printed it. So I guess this question should go to PE. Isn't lacquering damaging to a print or does it not affect the archival keeping as much as I've always thought? I know that in the past, many old timers including Stieglitz, varnished some of their work and that it yellows with age but lacquer doesn't seem to yellow at all and doesn't appear to have damaged the print at all. Didn't Kodak sell a Photo Lacquer not too long ago? I sure hope someone can shed light on these questions.
