Water transfer technology process

The water transfer printing technique is a type of printing in which a transfer printing paper/plastic film with a color pattern is hydrolyzed by water pressure.

— Extensive transfer objects

★ all kinds of decals

1, printed ceramic flower paper. Can be used for ceramic tableware, ceramic ware and other daily-use ceramics pattern production, can also be used for waist line, decorative tiles, decorative ceramics and other architectural tiles.

2, printed glass paper. Can be used for glass ware, glass bottles, advertising cups, all kinds of glass containers and decorative glass.

3, printed helmet paper. Widely used in motorcycle helmets, helmets and other surface pattern production.

5. Indoor building materials: doors, windows, floors, and wallboards.

Second, water transfer process

Production of water transfer printing paper → flower paper soaking → pattern transfer → drying → finished product

1, the production of water transfer printing paper. According to the required pattern, computer processing is performed to output the negative film plate, and then various color patterns are printed on the water transfer bottom paper (the specially processed paper is not required to be processed), and then the cover is printed on the patterned bottom paper. oil. Another method is to use a color laser printer to print the pattern directly onto the water transfer backing paper and then perform the water transfer.

2, soaked paper. Put the printed paper into the water, soak it in the water for 30s, and wait for it to slide. Note that the soaking time should not be too long, otherwise it will dissolve the glue on the paper surface.

3, the pattern posted paste. First, the surface of the object to be transferred is treated, and then the soaked paper is transferred onto it, and excess water is scraped off and dried.

4, dry. Items such as metal, ceramics, and glass are placed in an oven and baked at 140°C for 20 minutes; plastic items are baked at 70°C for 60 minutes; candles, helmets, or tempered glass are not baked.

5, finished product. A transparent varnish is sprayed on the flower surface of the baked goods and dried for 12 hours to permanently combine the flower face and the decoration. If you do not do this procedure can be, but the fastness is not good.

★ water transfer process can be divided into seven steps to operate:

1. Coating film: The water-soluble film is pre-printed with the desired pattern;

2. Activation: A special solvent is used to activate the pattern on the film to an ink state.

3. Draping: The pattern is transferred onto the object to be printed using water pressure.

4. Washing: Rinse the impurities remaining on the printed workpieces with water.

5. Drying: Dry the printed workpiece.

6. Spray paint: Spray PU transparent varnish to protect the surface of the printed workpiece.

7. Drying: Dry the surface of the sprayed finish.

★ Water transfer technology (the principle of water drape)

There are two types of water transfer technology, one is water mark transfer technology, and the other is water drape transfer technology. The former mainly completes the transfer of text and photo designs, while the latter tends to complete the entire product surface. Transfer. Cubic Transfer uses an aqueous film that dissolves easily in water to carry graphics. Due to the excellent tension of the water drape 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 like a paint spray. Drapery transfer technology can apply color patterns to any shape of workpiece to solve the problem of stereoscopic product printing for manufacturers. Curved surface coating can also add different lines on the surface of the product, such as skin texture, wood grain, emerald grain, and marble stone, etc., and can also avoid the often-existing virtual position in the general surface printing. In the printing process, since the surface of the product does not need to be in contact with the printing film, damage to the product surface and its integrity can be avoided.

The water-transfer printing film with special chemical treatment is printed on the surface of water after being printed with the desired color pattern, and the color texture pattern is evenly transferred onto the surface of the product by the action of water pressure. It is automatically dissolved in water, cleaned and dried, and then a transparent protective coating is applied. At this time, the product has shown a completely different visual effect.
