Hydrographic or HydroGraphics , also known as immersion printing , water transfer printing , water transfer imaging , hydro dipping , watermarbling or cubic printing , is a method for applying a printed design to a three-dimensional surface. The hydrographic process can be used in metals, plastics, glass, hardwoods, and various other materials.

Histori
The origin of the water transfer printing process is unclear. However, the first registered hydrographic apparatus for the US patent was Motoyasu Nakanishi of Kabushiki Kaisha Cubic Engineering on 26 July 1982. The abstract reads, "[a] the printing apparatus is equipped with a structure that supplies the transcription film into a fluid-filled transcription tub so that the transcription film is stored on top of the liquid, the structure that keeps the liquid stream in the direction in which the film is provided, and the structure that is sloping down the article to be printed into the liquid in the transcription bath from upstream to downstream from the liquid.

Process
The water transfer printing process is widely used to decorate items ranging from all-terrain vehicles and car dashboards to small items such as bicycle helmets or other automotive trims. Films can be applied to all types of substrates including plastics, fiberglass, wood, ceramics, and metals. For the most part, if the goods can be dipped into water and can be painted using traditional techniques then the hydrographic printing process can be used.
In the process, the substrate piece to be printed first passes through the entire painting process: surface preparation, sieving, painting, and clear coating. After painting but before the clear coating, the part is ready for processing. The polyvinyl alcohol hydrograph film, which has gravure printing with graphic images to be transferred, is placed carefully on the water surface in the dipping tank. The clear film dissolves in water, and dissolves after applying the activator solution. Once the dyeing begins, the surface tension of the water will allow a curved pattern around any shape. The remaining residue is then rinsed cleanly. Ink is attached and will not disappear. It was then left to dry.
Adhesion is the result of a chemical component of the activator softening the base layer layer and allowing the ink to form a bond with it. One of the most common causes of failure to achieve adhesion between two layers is a poorly applied activator. This can be either too many activators applied or too little.
Quality drive is one of the most important elements in producing high quality and professional hydrographic transfers.
