Default I think I under exposed ??

Well I think my first attempt to expose a screen was succesful for the most part.... just not printable

Anyway, I know it's not the best light source but I used one of those halogen 500W set ups, exposing for 12.5 minutes on 110 mesh - I used ProChem DXP Pink dual cure diazo emulsion. I'm making a table top exposure unit but wanted to see if I could have any luck with the halogen light.

You can see I have some good crisp lines in the bottom portions of the image however the top parts of the image are kinda raggity.




Am I right to assess that it was under exposed? I blew out the image with my pressure washer at it's lowest setting (you can easily put you hand in it) and it took a little while for it to start clearing out.

Is it common with this type of emulsion to it to get tacky when wet?

With a properly exposed screen just how durable is exposed emulsion? should I have to worry about too aggressively trying to clean out my image?

Thanks in advance.... I really did try to search for my answers but not much luck.
