Hydrographics or HydroGraphics, also known as immersion printing, water transfer printing, water transfer imaging, hydro dipping, watermarbling or cubic printing, is a method of applying printed designs to three-dimensional surfaces. The resulting combinations may be considered decorative art or applied art. The hydrographic process can be used on metal, plastic, glass, hard woods, and various other materials.[1]
History
The exact origin of the water transfer printing process is unclear. However, the first hydrographic apparatus registered for a US patent was by Motoyasu Nakanishi of Cubic Engineering KK on July 26, 1982. Its abstract reads, "[a] printing apparatus provided with a structure which supplies a transcription film into a transcription tub containing a liquid so that the transcription film is kept afloat on the liquid, a structure which makes the liquid flow in a direction in which the film is supplied, and a structure which slantingly immerses an article to be printed into the liquid in the transcription tub from an upstream position to a downstream position of the liquid."[2]
Usage
The water transfer printing process is extensively used to decorate items that range from entire all-terrain vehicles and car dashboards, to small items like bike helmets or other automotive trim. Films can be applied to all types of substrates including plastic, fiberglass, wood, ceramics, and metal. For the most part, if the item can be dipped in water and can be painted using traditional techniques then the hydrographic printing process can be used.[3]
Process
In the process, the substrate piece to be printed first goes through the entire painting process: surface preparation, priming, painting, and clear coating.[4] After painting but before clear coating, the part is ready to be processed. A polyvinyl alcohol hydrographic film, which has been gravure-printed with the graphic image to be transferred, is carefully placed on the water's surface in the dipping tank. The clear film is water-soluble, and dissolves after applying an activator solution. Once dipping is begun, the surface tension of the water will allow the pattern to curve around any shape.[citation needed] Any remaining residue is then rinsed off thoroughly. The ink has already adhered and will not wash off. It is then allowed to dry.[5]
The adhesion is a result of the chemical components of the activator softening the base coat layer and allowing the ink to form a bond with it. One of the most common causes of a failure to achieve adhesion between the two layers is a poorly applied activator. This can be either too much activator being applied or too little.[6]
