A&E DECEMBER 2016 • 19 Laser Engraving an item, product or substrate, there is no going back. So for those who engrave a customer's own products, there is always some sort of inherent risk involved. At our shop, we have a drawer full of hard educational evidence including assorted coffee mugs, beer steins, desk accesso- ries and even iPads that we have had to replace due to unexpected results.

The previous engraving was completed using either an Nd:YAG or fiber laser, and the graphics in question were black, also known as annealed. Annealing is comprised of laser marking the metal surface and forcing the carbon in the metal to rise to the surface.
