Etching is a process whereby any metal that is not protected with a resist is etched away in an acid bath or by an electrolytic process with  appropriate chemicals resulting in a dimensional piece with the resist's pattern raised.  The possibilities are endless and through a photo-etching process, I can etch any graphic or text, too.
