Metal thermal transfer: What are the differences between printing process and digital printing
The thermal transfer printing process is a new method of printing patterns on products of various materials, and is particularly suitable for producing a small number of personalized and customized products, and printing patterns containing full-color images or photos. The principle is to print the digital pattern on a special transfer paper with a special thermal transfer ink through a printer, and then use a special transfer machine to accurately transfer the pattern to the surface of the product at high temperature and pressure to complete the product printing.
Thermal transfer (thermal transfer ink) is an emerging printing process that has been introduced from abroad for more than 10 years. The thermal transfer printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing uses halftone printing to pre-print the pattern on the surface of the film. The printed pattern has rich layers, bright colors, kaleidoscopic changes, small color difference, and reproduction Good performance, can meet the requirements of the designer, and is suitable for mass production; the transfer process is processed by a heat transfer machine (heating and pressure) to transfer the exquisite pattern on the transfer film to the surface of the product, and the ink after forming The layer is integrated with the surface of the product, which is vivid and beautiful, greatly improving the grade of the product. However, due to the high technical content of this process, many materials need to be imported.
And a slightly better technology than thermal transfer is digital printing.
Digital Express Printing is a systematic project involving cutting-edge technologies such as CAD technology, network communication technology, precision machining technology, and fine chemical technology. It is a product of the integration of information technology with traditional technologies such as machinery, textiles, and chemicals.
Traditional printing is inseparable from the use of flat screens and rotary screens. However, the cost and time consumed by plate making cannot meet the modern printing trend of small batches and multiple varieties. Therefore, the development of a plateless and pressureless digital printing. The basic principle is the same as that of an inkjet printer.
As digital jet printing technology involves a lot of calculation and control, it can be said that there is no digital jet printing technology without today's high-speed computers. For now, the development of digital jet printing technology is basically synchronized with the working capabilities of computers, and the development of computer technology still shows no signs of weakening. With the development of computer technology, it can be expected that digital printing technology will develop at a high speed in the future. . At the same time, the manufacturing technology of the nozzle also benefits from the related technologies of integrated circuits, such as etching and precision assembly. The continuous appearance of modern high-frequency, multi-nozzle nozzles proves this point.
