Five years ago, a dear friend designed the logo for my business, which I subsequently protected with a service mark. Although I paid her for her work I wanted to say thank you with more than just money.
Having an interest in decorative etching (among other steampunk pretensions), I decided to etch the service mark from the patent office into a 9 x 12 sheet of solid copper. After trying to transfer etch resist to the plate a number of ways (transparency and newsprint and a hot iron didn’t give sufficient quality), I finally hit on success after BrantH suggested I spray paint it, and remove the paint with the laser cutter. Here’s the process from start to end.
