Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Hi Stuart:

I had essentially the same problem using a cheap HP Inkjet printer.

My solution was to print my PCB images (artwork) on a good grade of
tracing paper.
I make two (yes two) copies. The copies will be exact images of each other.
Then, I overlay one copy over another. I can get perfect registration
between
the two identical copies.

This technique increases (doubles) the black density of the inkjet ink.
I then use photoresist coated copper-clad PCB stock and conventional
expose-develop-etch.

I etch with muriatic acid/peroxide solution.

Works good for me.
