Hydrographics. Ever heard of it? I hadn’t until recently. Graphics we all know, but hydro – doesn’t that mean water? This process of applying graphics to non flat objects is something out of a science fiction movie. Basically – water transfer printing. Sounds weird right?
Wikipedia explains it as:
Hydrographics, also known as immersion printing, water transfer printing, water transfer imaging, or cubic printing, is a method of applying printed designs to three-dimensional objects. The hydrographic process can be used on metal, plastic, glass, hard woods, and various other materials. In the process, the substrate piece to be printed is pre-treated and a base coat material is applied. A polyvinyl alcohol film is gravure-printed with the graphic image to be transferred, and is then floated on the surface of a vat of water. An activator chemical is sprayed on the film to dissolve it into a liquid and activate a bonding agent. The piece is then lowered into the vat, through the floating ink layer, which wraps around and adheres to it. After removing the piece from the water, a top coat is applied to protect the design. With multiple dippings, hydrographics printing can achieve full 360° coverage of the part surface, including small crevices. 
From an overview and in text form, it’s still pretty hard to understand what this means. Printing via water immersion didn’t make sense to me, so I jumped on over to YouTube for further detail. Check out some of the great videos I found there.
Pretty cool right?! Anyone out there have experience in this? I would love to hear more - is it as easy as they make it seem?
