Thanks for the reply Bob,
Could be part of the problem, I started with a standard sort of Grow-
lite by GE but did not know how much if any UV was in it, so switched
to the Photoflood bulb.
I am basing this switch on a web page where the person has made many
boards with one using KPR, which is supposed to be very similar. I
don't really know how much UV the bulb I have is putting out though.
I will dig around a bit more. So far both lights are producing very
similar results.
I may try another negative, right now I have very little black in
mine because the circuit is sitting in a ground plane, traces only
slightly seperated. Possibly I can tell whats going on with wider
space between light and dark areas of the negative.
Again thanks for the reply,
ED
