Homebrew PCBs

I have never used this but assume its like normal silkscreening.
Basically think of like womens stockings stretched tight over 
something.

Then coat it with the stuff, what gets light hardens and plugs the 
netting/holes and the rest washes out leaving fine holes to press 
the resist through. 

The holes are much finer and so on this is just a quick visual.
