According to the water drape transfer, the plastic film dissolved in water is used for transfer. Since the film has a very good stretch ratio, it is easily entangled on the surface of the object, and is suitable for various complicated shapes.

When performing water drape transfer, the graphic is first printed on a water-soluble plastic film (PVA film) to form a water drape transfer film. After the water drape transfer film is spread on the water surface, the spray activator dissolves and destroys the PVA, and the image becomes a free state. The object is then pressed from top to bottom into the water, and the activated image is transferred to the surface of the object under water pressure. Finally, water washing, drying, cooling and the like are performed. Since the water-drawing transfer film has a relatively large stretchability, the image after transfer is easily deformed, so that the transfer is usually a pattern such as wood grain, marble grain, animal skin grain, etc., which does not affect the ornamental property.
