Hydrographics or 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.[1] 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.[2] 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.[3] 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.[4] [5] [6]
