Been spending a lot of time on here!
Would I be better off using germicidal UV-C or regular blacklight (UV-A/B) bulbs for dichromated colloids? I know that the germacidal bulbs are more expensive, but if they provide significantly more exposure, they'd be worth it. I hate waiting.
I know that sodium dichromate has a peak sensitivity below 300nm, but the glass to hold the negative will absorb much of the radiation below about 400nm. Without using UV transmitting glass, will any of the UV-C radiation reach the print? Do germicidal bulbs emit more UV-A/B radiation than blacklight bulbs? Am I over thinking the issue, like I usually do?
