Hi all, I purchased a brand new NuArc 26-1KS plate burner a couple of months ago, for the purpose printing with UV sensitive alternative processes. I've just had time to use/test it and I think there's something seriously wrong with the device; I currently struggle with pop palladium (Li2PdCl4 + AFO or Na2PdCl4 + AFO, noble metal solutions' concentration 0.52M, AFO concentration 1.05M), and the exposure times are incredibly long. I was using a bank of UVBL tubes before (Philips 40W, /05 series - not manufactured anymore, replaced with /10 series recently), and my standard exposure time (with a 31-step tablet) was 6:30, giving me 28 distinct steps including dmax and paper white. With the NuArc, I print for 900 units (17:15), and the step tablet test says I still have to give 1 stop more exposure for being able to get 28 distinct steps, and more importantly I'm currently getting a pretty anemic result with low dmax. Awful. Something's wrong, WRONG! What is your usual pt/pd (or any other print out iron process) printing time (not units, time!) with this unit? (Or, similar units?) What could cause the problem? I'm suspecting the bulb (NP-80) but it's a brand new unit and I just don't get how could a brand new bulb work that much slow? (The visible light illumination is pretty strong BTW.) TIA, Loris.
