Never split hairs when dealing with a smart-ass. I have only begun to snark. Diazo is a word most people don't know, but it is a UV contact exposure process by definition. I used one of these machines for 25 years, Snarky. Not everyone used them for pin-registered multiple exposures. We etched film negatives with them and made color proofs as well. We needed the vaccum feature to minimize any film distortion from entrapped air bubbles.
I agreed with you every time you took a step in the right direction. Next time I won't be so generous with the clues. I would assume that you would have known the vacuum feature and mentioned that when I showed the fans, since you used one for so long I gave you your props all along but nowhere in your first two answers did you mention what made this table different from a standard light table. It's ok, I don't mind leading y'all to the correct answer. Nevertheless, you win this one.
