Introduction to Water Transfer Printing - Water Overlay

1、 Water drape
　　Water coating is a type of water transfer printing, which refers to the decoration of the entire surface of an object, covering the original surface of the workpiece, and being able to print patterns on the entire surface of the object. It is also known as universal transfer printing because it can transfer any complex surface or concave convex shaped workpiece

　　2、 Introduction
　　The water coating process can dry the surface of various processed materials such as EVAPVC.PP, ABS. PU resin, ceramic hardware, glass, and other products. Add a layer of natural texture "wood grain, marble, peach wood, flowers and other colors" to the product to increase the additional price of the product

　　Value. This technology is developed for the transfer printing of complex shapes and printing dead corners that cannot be overcome by traditional printing, heat transfer printing, transfer printing, and silk screen printing.

3、 Water covered film
　　Similar to the production process of heat transfer film, the water polo transfer film is printed using a traditional printing process using a gravure printing machine on the surface of water-soluble polyoxymethylene film. The substrate of the water pineapple transfer printing film has a very high elasticity, making it easy to tightly adhere to the surface of dry objects, which is also the main reason why it is suitable for transfer printing on the entire surface of the object. However, the drawback of large scalability is also obvious, that is, during the printing and transfer process, the images and text on the surface of the film are prone to deformation; Secondly, if the transfer process is not handled properly, the film may break. To avoid this drawback, we often design the graphics and text on the water transfer film to have no specific shape, and the deformation does not affect the repeated patterns of the viewing hall. The water transfer film can achieve high elongation when printed on a gravure printing machine, and the printing cost can be greatly reduced. At the same time, the gravure printing machine has an accurate tension automatic control system, which can print 4 to 8 colors at once, with high overprinting accuracy, Gravure printing water transfer film uses water transfer printing ink. Compared with traditional ink, water transfer printing ink has good water resistance and the drying method is volatile drying

　　4、 Application scope
　　① Automotive craftsmanship, such as steering wheel, dashboard, door handles, and other interior decorations.
　　② Home appliance industries such as air humidifiers, refrigerators, audio systems, etc.
　　③ Daily boutiques: luggage decoration, pen holder, desk calendar holder, hair accessories, makeup box, art photo frame
　　④ Communication products such as mobile phones, telephones, etc.
　　⑤ The construction and decoration industry. For example, doors, decorative panels, etc.
　　⑥ Stationery and gift industry. For example, alarm clocks, wall clocks, pendants, handicrafts, etc.
　　⑦ The computer industry. For example: mouse, printer, speaker, chassis, etc,
　　⑧ Furniture industry. For example, high-end imitation wood grain furniture, imitation wood grain boards, etc.
　　⑨ Other industries. For example, instruments and meters, sports equipment, shoe materials, shoe soles, shoe coffins, shoe upper components, etc.

　　From a mechanistic perspective, as long as the beauty surface can be coated with paint, the object can be transferred and printed with water. Currently, the main use is to use imitation wood grain on the surface of dry plastic (ARSPP PFT PVC nylon, etc.), imitation natural wood grain decoration on the surface of artificial wood, and colored steel plates

　　Decorative ceramic pose decals
　　5、 Process flow
　　(1) Transfer film
　　Preprint the required pattern on a water-soluble film, provided by the film supplier
　　(2) Release film
　　Cut the wrapping film into the required specifications for the workpiece and place it on the water surface to drain the water
