What is the difference between thermal transfer printing technology and digital printing technology?
What is thermal transfer printing technology?
Thermal transfer printing is a new way to print patterns on a variety of materials, especially for making a small variety of personalized and customized products, as well as printing patterns containing full-color images or photos. The principle is that the digital pattern is printed on the transfer special paper through the printer with special transfer ink, and then the special transfer machine is used to accurately transfer the pattern to the surface of the product at high temperature and high pressure to complete the printing of the product.
The commonly used thermal transfer printing technology is a transfer technology and product, which uses a thermal transfer device to heat the pattern and image on the thermal transfer paper to 180C0--230C0 and transfer it to different material media. The thermal transfer technology was first applied in the clothing printing, textile printing and dyeing industry and shoe material industry.
Later, with the development of the times and the advancement of technology, the application fields are increasing. Especially the emergence of digital technology and the emergence of personalized consumption concepts have made the application of thermal transfer technology more popular and extensive. The application products are endless and cover almost all material fields. . For example, metal, wood, stone, ceramic, glass, PVC, leather, chemical fiber fabrics can be transferred to beautiful patterns and images using thermal transfer technology to produce and produce exquisite products.
The difference between thermal transfer and digital printing:
Thermal transfer printing technology is an emerging printing process that has been introduced abroad for more than 10 years. The printing method of the process is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing, and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, colorful, ever-changing, small color difference, reproducibility. Well, can achieve the effect of designing the pattern, and is suitable for mass production; transfer processing through the thermal transfer machine one-time processing (heating and pressing) transfer the fine pattern on the transfer film on the surface of the product, after forming the ink layer It is integrated with the surface of the product, which is beautiful and beautiful, greatly improving the grade of the product. However, due to the high technical content of the process, many materials need to be imported.
The digital printing is a little better than the thermal transfer printing technology: digital printing is a systematic project involving cutting-edge technology such as CAD technology, network communication technology, precision machining technology and fine chemical technology. It is information technology and machinery. A fusion of traditional technologies such as textiles and chemicals.
Traditional printing is inseparable from the use of flat nets and round nets. However, the cost and time consumed by plate making cannot meet the trend of modern printing in small batches and varieties, so it develops a digital version without pressure. printing. The basic principle is the same as that of an inkjet printer.
Since digital jet printing technology involves a large amount of calculation and control, it can be said that digital jet printing technology cannot be realized without today's high-speed computer. For now, the development of digital jet printing technology is basically in sync with the working ability of computers, and the development of computer technology still has no signs of weakening. With the development of computer technology, it is expected that the future digital printing technology will also have rapid development. . At the same time, the manufacturing technology of the nozzle also benefits from related technologies of integrated circuits, such as etching and precision assembly. This is evidenced by the constant emergence of modern high-frequency, multi-nozzle nozzles.
