Homebrew PCBs

I think we touched on this subject before, but now that I've got some boards
done I'm wanting to revisit it.  I would like to silkscreen the parts
placement patterns onto the back side of my boards here.. just to aid in
placement and also for looks.  I am wondering if someone back in the early
1970s would have had a way to do this, short of drawing it out by hand.  I'm
assuming photocopiers existed at the time. could you do a toner transfer to
the PCB fiberglass?  I"ve not attempted it yet. 

 

I'd really love to have the parts placement in white, but of course, that's
not available.  I could do yellow, I suppose, assuming the transfer process
would work.  Other ways I've thought of are manually cutting out the
patterns (uggggh) with an xacto knife and then just keeping those templates
for future use.

 

And then there's real silkscreening.. but I just can't seem to wrap my head
around the process of making the screens.

 

Apparently there are now (very expensive) laser printers out there that
actually print true white.  

 

Thoughts, ideas?
