I think it mostly depends on the emulsion you use. I have used 2 part darkroom style emulsion and expose it with a regular worklight which works pretty well. I have also used the pre-mix out of the tub stuff and used sunlight exposure in which case it does take a while (30 min. minimum) and you have to be sure your black backing is firmly pressed to the screen if you want it to be at all accurate.
At a commercial shop they use light tables which use an array of fluorescent bulbs. With these you would be able to make process prints and hold very fine detail.
