What is thermal transfer printing？
Thermal transfer printing technology has been used in fabric thermal transfer printing for a long time. Thermal transfer printing is now used to print patterns on products made of a variety of materials. Particularly suitable for the production of a wide range of personalized and customized products in small batches, as well as printing including full-color images.
Or the pattern of the photo, the heat transfer process, after designing the pattern, making a copper plate, and then using an electric engraving machine to engrave patterns of different colors on the copper plate. With the rapid development of high and new technologies, the application of thermal transfer printing technology is becoming increasingly widespread.
The Ink types are divided into heat press transfer type and sublimation transfer type. The objects to be transferred include fabrics, plastics (boards, sheets, films), ceramics metal-coated plates, etc.; printing methods can be divided into screen printing, offset printing, gravure printing, relief printing, inkjet, and ribbon printing; from Substrate, categories include heat transfer paper and heat transfer plastic film.
It is not only used on the surface of various ABS, PP, plastic, wood, coated metal, and other products but also involves applications in the wood industry. It is more widely used in medals, wooden pallets, door panels, furniture, handicrafts, paint-free doors and other melamine door panels, irregular edge sealing, etc. The thermal transfer printing process is widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery, and other industries. The equipment used in the thermal transfer process includes a cup baking machine, lid baking machine, baking tray machine, direct pressure heat transfer machine, shaking head heat transfer machine, etc. The required consumables include professional heat transfer paper and heat transfer printing machine ink. Add a printer, computer, and digital camera to complete the thermal transfer printing project.
What are the parts of thermal transfer printing? (Process classification of thermal transfer printing)
The printing method of this process is divided into two parts: transfer film printing and transfer processing.
Transfer film printing: The brush uses dot printing (resolution up to 300 dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color differences and good reproducibility, and can meet the requirements of the pattern designer. , and suitable for mass production.
Thermal transfer processing: The exquisite pattern on the transfer film is transferred to the surface of the product through one-time processing (heating and pressurization) of the thermal transfer machine. After molding, the ink layer and the surface of the product dissolve into one. Thermal transfer printing is of great decorative value. , which can greatly increase the added value of your products and greatly improve the quality of your products. However, due to the high technical content of this process, many materials need to be imported.
Its main features are that the transfer image is brightly colored, rich in layers, and durable. The image will not fall off, crack, or fade. Its effect is comparable to printing. The difference from printing is that thermal transfer uses heat at high temperatures. The transfer ink sublimates when heated penetrates into the surface of the object and forms a brightly colored image after sublimation.
