Transfer printing is a printing technique that transfers the image on the intermediate carrier to the substrate using the corresponding pressure. Can be divided into: water transfer, gas transfer, screen transfer, thermal transfer.

 

Thermal transfer technology

 

Production Process

The lithographic thermal transfer production process uses a film cutter to cut the thermal transfer paper roll into a desired size. The second is to attach the thermal transfer paper film to the surface of the workpiece and place it on the flat hot stamping machine. The third is to push the plate to the heating zone of the flat heat transfer machine, press the pressure plate switch, press the plate to press the thermal transfer paper tightly on the workpiece, heat and keep it for one minute. The fourth is to raise the pressure plate, push the workpiece to the piece, remove the transfer film and remove the workpiece and check.

 

Application range

Thermal transfer technology is widely used in electrical appliances, daily necessities, building materials and so on. Due to its resistance to corrosion, impact, aging, abrasion, fire, and non-discoloration for 15 years in outdoor use, almost all products are manufactured in this way. For example, when you open the phone case, you can see the dense barcode label inside. Many label requirements can stand the test of time, no deformation for a long time, no fading, no wear due to contact with solvents, no discoloration due to high temperature, etc. Therefore, it is necessary to use a special material printing medium and printing materials to ensure these characteristics, generally Inkjet and laser printing technologies are not available.

 

Water transfer technology

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: a) film printing: printing various patterns on the polymer film; b) 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); 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 the printed object; IX) Drying: Dry the surface of the finished object.

 

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. The 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. 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.

 

Transfer refers to a printing method in which the image on the intermediate carrier film is transferred to the receiving object by corresponding pressure! It is impossible to print the pattern on ordinary glass, and it is necessary to use the intermediate carrier! After the ink, the image is displayed, and the surface of the medium is strongly adhered to form a personalized product! The thermal transfer coating is a colorless and impurity-free clear transparent polymer material, mainly based on acrylic resin, and other resins. It has the characteristics of high hardness and strong adhesion. It is suitable for ceramic, stone, metal and other high temperature resistant materials. The thermal transfer effect is clear, the color is gorgeous, the expression is strong, the reduction degree is good, and the original effect is conveyed.

Digital thermal transfer products are not a single product market, it is a multi-form, multi-variety, a comprehensive market across multiple industries! Digital thermal transfer color printing inks can be adapted to a wide range of supplies by using thermal transfer paper, such as A variety of chemical fiber fabrics, various hard materials such as metal, wood, stone, ceramics, glass, PVC, leather PU, etc., combined with thermal transfer technology to produce personalized products without plate making, for personalized market The development has brought new space. These materials can be used in clothing, printing and dyeing, decoration, crafts, light industry, gifts, advertising, art, photography, tourism, building materials and other industries! For different media, the coating used is naturally different!

 

Thermal transfer advantages and disadvantages

AdvantageS:

1, the printing step is simple

2, will not cause damage to the material

3, accurate printing position

4, very suitable for photo printing that requires color transition

5, suitable for more professional use in uncommon industries

6, suitable for printing of multiple materials

 

Disadvantages: Professional thermal transfer equipment is required. For ceramics, metals and other items, a thermal transfer coating is required on the surface.
