Hydro graphics or Hydro Graphics, also known as immersion printing, water
transfer printing, water transfer imaging, or cubic printing, is a method of
applying printed designs to three-dimensional surfaces. The hydro graphic process
can be used on metal, plastic, glass, hard woods, and various other materials.
Also known as "hydro dipping".
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 drippings, hydro graphics printing can
achieve full 360° coverage of the part surface,
including small crevices
