Abstract
A method of etching a plurality of identifying characters into a wire tag for macro-organisms is disclosed. The method includes the steps of coating the tag with photoresist, exposing a defined portion of the coated tag to light, the defined portion corresponding to the characters, removing a portion of the photoresist, with that removed portion also corresponding to the characters, and etching the uncoated portion of the tag. Thus, a pattern will be etched into the tag which corresponds to the characters. This provides a means for rapidly, inexpensively, and indelibly marking wire tags in a manner which is superior to the methods proposed in the prior art.
