I've been reading up about using laser printers to make iron on etch resist patterns. Does anyone have any experience? Previously I've used a resist pen (sharpie). I want to make neater and thinner traces now, so I figured I'd start using my laser printer. What sort of paper do you use? Any special techniques? Got any tips you'd like to share? What about the etchant? Is ferric chloride OK or will I have to use something else?
