Cupric Calligraphics May 23, 2011Posted by stuffilikenet in Photography, Publishing Tools, Toys.
This guy makes copper printing plate the same way we make circuit boards (ferric chloride).
The prints come out really nicely. I didn’t ask him what ink he uses, but I suspect it’s a standard oil-based one. This can be a nice method: you can print delicate traces using this kind of technology just like circuit boards.
