Hydro-Dipping is the process that transfers an image or pattern to a 3D surface. Traditional printing methods cannot fully print on 3D objects, especially if there is hard to reach areas, or if the object is odd shaped. The water transfer printing process eliminates these issues by submerging the item into water, covering the whole surface.
The hydrographics process can be done on any material that can hold the base coat and that can be submerged into water safely. Some materials that the process works on include metals, wood, plastic, stone, Bakelite, ceramic, etc.
