Heat transfer printing is a new method of printing patterns on goods of various materials. It is especially suitable for making a small number of personalized and customized goods and 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 commodity surface at high temperature and high pressure to complete the commodity printing.
Heat transfer printing is a new printing technology, which has been introduced 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 patterns are pre-printed on the film surface. The printed patterns have rich levels, bright colors, ever-changing, small color differences, and good reproducibility, which can meet the requirements of the designer, and is suitable for mass production; Transfer processing transfers the exquisite patterns on the transfer film on the product surface through one-time processing (heating and pressurization) of the heat transfer machine. After forming, the ink layer is dissolved into one with the product surface, which is realistic and beautiful, and greatly improves the grade of the product. However, due to the high technical content of this process, many materials need to be imported.
Digital fast printing is a system engineering, involving cutting-edge technologies such as CAD technology, network communication technology, precision machining technology, and fine chemical technology. It is the product of the integration of information technology and traditional technologies such as machinery, textile, and chemical industry.
Traditional printing is inseparable from the flat screen and round screen. However, the cost and time consumed in plate making can not meet the modern printing trend of small-batch and multiple varieties. Therefore, digital printing without plate and pressure has been developed. Its basic principle is the same as that of inkjet printers.
Because digital jet printing technology involves a lot of calculation and control, it can be said that there can be no digital jet printing technology without today’s high-speed computer. At present, the development of digital jet printing technology is basically synchronized with the working ability of computers, and there is still no sign of weakening in the development of computer technology. With the development of computer technology, it can be expected that digital printing technology will also develop at a high speed in the future. At the same time, the manufacturing technology of nozzle also benefits from the related technology of integrated circuits, such as etching, precision assembly, and so on. The continuous emergence of modern high-frequency and multi-nozzle nozzles proves this.
