Hi Everyone,

Today we are going to share some details of a process which is catching up really fast with likes of the the Indian customers and that is ‘HYDROGRAPHICS’.People know about Hydro Graphics by their other names like hydro dipping,water transfer printing, immersion printing etc.

Hydrographics is a process where a graphic design etc is transferred on to a panel or part  of the car,bike or any other vehicle with the help of water.In the process, the substrate piece to be printed first goes through the entire painting process: surface preparation, priming, painting, and clear coating.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.Any remaining residue is then rinsed off thoroughly. The ink has already adhered and will not wash off. It is then allowed to dry.
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.
