Water transfer printing is environmentally friendly technology

There are two types of water transfer technology, one is water mark transfer technology, and the other is water coating transfer technology. The former mainly completes the transfer of text and photo patterns, while the latter tends to complete the entire product surface. The transfer printing technology uses a water-based film that is easily dissolved in water to carry the graphics. Due to the excellent tension of the water-coated film, it is easy to wrap around the product surface to form a graphic layer, and the product surface gets a completely different appearance just like spray paint. Coating #transfer technology can coat color patterns on workpieces of any shape, solving the problem of three-dimensional product printing for manufacturers. Surface coating can also add different textures on the surface of the product, such as leather texture, wood texture, jadeite texture and marble texture, etc., and at the same time, it can also avoid the virtual position that often occurs in general board printing. And in the printing process, since the product surface does not need to be in contact with the printing film, damage to the product surface and its integrity can be avoided.

Water transfer uses water pressure and activator to dissolve and transfer the peeling layer on the water transfer carrier film. The basic process is:

1. Film printing: printing various patterns on the polymer film;


2. Spray primer: Many materials must be coated with a layer of adhesive, such as metal, ceramics, etc. If you want to transfer different patterns, you must use different background colors, such as brown, brown, khaki, etc. for wood grain. The stone pattern basically uses white, etc.;

3. Extension of the film: let the film lay flat on the water surface, and wait for the film to be stretched flat;

4. Activation: The pattern of the transfer film is activated into an ink state with a special solvent (activator);

5. Transfer: use water pressure to print the activated pattern on the printed object;

6. Washing: Wash the remaining impurities of the printed workpiece with water;

7. Drying: Dry the printed workpiece, and the temperature depends on the rawness and melting point of the material;

Eight, spray paint: spray transparent protective paint to protect the surface of the printed object;

9. Drying: Dry the surface of the object that has been sprayed with the topcoat.
