The difference between thermal transfer and digital thermal transfer

Generally speaking, thermal transfer is a kind of transfer technology and product. It uses thermal transfer equipment to transfer patterns and images on thermal transfer paper to 180C0--230C0, and transfer and print on different materials. The thermal transfer technology was first applied in the textile printing and dyeing industry and shoe material industry. Later, with the development of the times and the advancement of science and technology applications, the emergence of digital technology and the emergence of personalized consumption concepts have made the application of thermal transfer technology more widespread and widespread. The application products have emerged in an endless stream, covering almost all material fields. . Such as: metal, wood, stone, ceramics, glass, PVC, leather, chemical fiber fabrics can apply thermal transfer technology to transfer beautiful patterns and images, production and production of exquisite products.

Thermal transfer has two kinds of printing methods, one is sublimation transfer printing, and the other is thermal transfer printing. The sublimation method refers to the printing of a pattern on a printing paper to a desired medium after the color paste produced by the heat-raising disperse dye is printed on a screen or a gravure plate to form a printing paper, and the heat-setting transfer mode refers to the use of heat. Solid ink (also known as hot-melt adhesive) is printed on screen printing paper, and the pattern on the printing paper is transferred to cultural shirts and clothing and other products. The two printing methods have obvious differences in application, sublimation transfer printing method Mainly used in chemical fiber fabrics and hard materials coated with thermal transfer coating, heat-transfer printing methods are mainly used in pure cotton products.

The difference in the texture of the two printing methods is that the dye-sublimation pattern does not change the original texture of the material after transfer, and the hand feel and appearance are good. After the thermosetting pattern is transferred, a layer of jelly material is formed on the surface of the attachment, and the hand feel is poor and airtight. The two kinds of printing methods have their own advantages and disadvantages in production and have their own characteristics.

The traditional sublimation thermal transfer of several technical methods Traditional sublimation thermal transfer technology, there are three: silk screen thermal transfer, gravure (copper plate, electric engraving) thermal transfer, offset thermal transfer. The traditional sublimation thermal transfer feature is printed.

Digital thermal transfer is a new technology based on the traditional sublimation heat transfer printing combined with digital printing technology to print pattern images without printing. It is characterized by the use of digital printing technology to print color patterns and images without the need for plate making, which saves the plate making process and costs, and is therefore suitable for producing personalized printed products.

The technical feature of digital thermal transfer is that the digital printing device uses a dedicated thermal transfer color print ink and thermal transfer printing paper.
