Homebrew PCBs

I wonder why would anybody go that route? Paints use solvent and 
solvents call for ventillation unless someone doesn't believe in it.

Bottom line is, there is a perfect method of TT and I don't 
understand why someone says that it is not fast enough-- are we 
talking about  a contest of some kind??

Then for people who need/want/must have more resolution, there is a 
UV method, slightly more complex.

But silk screen? I was around silk screen lab for a while and unless 
you want to make PCBs on glass (for touch screens) or on ceramics 
(have no idea why) then silk screen is not a good method for home use 
unless someone enjoys an excercise in... futility.  Mike
