If you have the silk screens you should look into the process a few people
use. They do the photo exposed and developed silk screen then simply
silk screen on either solder paste or a thin tar like material. I don't 
know exactly
what the tar stuff is and I wish I did. We had one local guy who did proto 
boards
using the screens and they were perfect even the double sided as it was easy
to register positions on everything.

This is a bit more useful if you have the equipment and if you are doing 
more than
a couple of boards. I looked at getting the silkscreen setup a few years 
back and
it was going to cost too much for the few boards I needed. I just ordered 
500 boards
from a house and now I wish I had got the stuff. would have saved a few $$
