Water transfer technology

posted on   2019-06-17 09:30:58

Known as the more environmentally friendly technology, it is also the latest high-efficiency printing production, probably related to his departure from the ink in the printing process. Water transfer uses water pressure and activator to dissolve and transfer the release layer on the water transfer carrier film.

 

The basic flow is:

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

2.spraying 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 wood, brown, brown, earthy, etc. Etc.;

3.extension of the film: let the film lay flat on the water surface, and wait for the film to stretch flat;

4.activation: activate the pattern of the transfer film into an ink state with a special solvent (activator);

5.The water pressure will be printed on the printed matter after the activated pattern;

6.Washing: the impurities remaining on the printed workpiece are washed with water;

7.Drying: the workpiece to be printed is dried, and the temperature depends on the quality and melting point of the material.

8.Spray topcoat: spray a transparent protective paint to protect the surface of theprinted object;

9.Drying: Dry the surface of the finished object.

Technical classification

There are two types of water transfer technology, one is watermark transfer technology, the other is water drape transfer technology, the former mainly completes the transfer of text and photo patterns, while the latter tends to complete the entire product surface. Transfer. Cubic Transfer uses a water-based film that is easily dissolved in water to carry graphics. Due to the excellent tension of the water-coated film, it is easy to wrap around the surface of the product to form a graphic layer, and the surface of the product has a completely different appearance as a paint. Draping transfer technology can apply color patterns on workpieces of any shape, solving the problem of stereoscopic product printing for manufacturers. Surface coating can also add different lines on the surface of the product, such as skin, wood, jade and marble, and also avoid the imaginary position in the general board printing [1]. In the printing process, since the surface of the product does not need to be in contact with the printed film, damage to the surface and integrity of the product can be avoided.
