What is heat transfer? Why use heat transfer technology? Heat transfer is a new method of printing patterns on goods of various materials, especially suitable for the production of small and diverse personalized and customized goods, and for printing patterns containing full-color images or photos. The principle is to print the digital pattern on the special transfer paper with special transfer ink through the printer, and then use the special transfer machine to accurately transfer the pattern to the surface of the product at high temperature and high pressure to complete the product printing.
Heat transfer is a new printing process, which has been introduced from abroad for more than 10 years. The process printing method 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, bright in color, ever-changing, small in color difference, and reproducible. Good, it can meet the requirements of the designer of the pattern, and it is suitable for mass production; the transfer process transfers the exquisite pattern on the transfer film to the surface of the product through one-time processing (heating and pressure) of the heat press machine. The surface of the product is melted into one, realistic and beautiful, which greatly improves the grade of the product. However, due to the high technical content of this process, many materials need to be imported. And slightly better than heat transfer technology 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. Traditional printing is inseparable from the screen regardless of whether it uses a flat screen or a rotary screen. However, the cost and time consumed by plate making cannot meet the modern printing trend of small batches and multiple varieties. printing. The basic principle is the same as that of inkjet printers.
Since digital jet printing technology involves a lot of calculations and controls, it can be said that digital jet printing technology would not be possible without today's high-speed computers. As far as now, the development of digital jet printing technology is basically synchronized with the working ability of computers, and the development of computer technology has not shown any signs of weakening. With the development of computer technology, it can be expected that digital printing technology will also develop rapidly 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. This is evidenced by the continued emergence of modern high frequency, multi-nozzle sprinklers.
