Printing on Metal

I did some research on printing on metal. What I have found is that it involves treating the metal (often aluminum) with a chemical process known as anodization. This process involves placing the metal in a chemical bath to turn the metal into an anode, a charged substance that is commonly used in batteries. This treated metal will readily accept dyes and certain chemical pigments will infuse directly to the metal, creating a strong and vibrant design.

There are several sites online that will actually do this kind of printing for you. Prints on metal could make very interesting portfolio pieces or business cards.
