Need help reproducing a PCB

[Doug Ingraham]

If this is a one off all you need to do is print the negatives on
transparency material with a laser printer.
The laser printers tend to have a little more opacity than ink jets do but
I have done this with an ink jet
printer as well.  I also once plotted directly on the bare copper with a
sharpie and had it turn out ok.

Align the negatives on the sensitized board stock.
Expose.
Develop.
Etch.
Drill
Solder in your feed throughs.
Put the parts on the board.
Debug

If on the other hand you want to make even 5 boards you would be better off
with your approach.

Best wishes!
