The difference between heat transfer printing and digital heat transfer printing

generally speaking, heat transfer printing is a kind of transfer technology and product. It is a technical form of using heat transfer equipment to heat the patterns and images on the heat transfer paper to 180c0--230c0 for transfer printing on different material media. Heat transfer technology was first used in textile printing and dyeing industry and shoe material industry. Later, with the development of the times and the progress of science and technology, the application fields were increasing, especially the emergence of digital technology and the introduction of personalized consumption concept by Yang Gong, which made the application of heat transfer technology more popular and extensive, and the application products emerged in endlessly, covering almost all material fields. For example, heat transfer technology can be used to transfer exquisite patterns and images on metal, wood, stone, ceramics, glass, PVC, leather and chemical fiber fabrics to produce and make exquisite complex products

there are two printing methods for heat transfer printing, one is sublimation transfer printing, and the other is thermosetting transfer printing. Sublimation means that the patterns on the printing paper are transferred to the required media after the color paste produced with heat rising disperse dyes is printed into the printing paper with silk or intaglio. Thermosetting transfer means that the patterns on the printing paper are transferred to the cultural shirts, clothing and other products after the printing paper is printed into the printing paper with thermosetting ink (also known as hot melt adhesive). The two printing methods have obvious differences in application, Sublimation transfer is mainly applied to chemical fiber fabrics and hard materials coated with heat transfer coating, and thermosetting transfer is mainly applied to pure cotton products

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

several technical methods of traditional sublimation heat transfer there are three technical methods of traditional sublimation heat transfer: silk screen heat transfer, gravure (copper plate, electric engraving) heat transfer and offset heat transfer. Traditional sublimation heat transfer printing is characterized by plate printing

digital heat transfer printing is a new technology that combines the traditional sublimation heat transfer printing with digital printing technology to print pattern images in the form of plate free printing. It is characterized by the application of digital printing technology to print color patterns and images without plate making, which saves the plate making process and cost, so it is suitable for the production and printing of personalized products

the technical feature of digital heat transfer printing is that the digital printing equipment uses special heat transfer color printing ink and heat transfer printing paper
