How to distinguish and understand thermal transfer and digital thermal transfer
1. Two printing methods for thermal transfer There are two printing methods for thermal transfer, one is sublimation (used in the model gallery), and the other is thermosetting. The sublimation method refers to the use of heat sublimation After the color paste produced by the disperse dye is printed into printing paper by screen or gravure, the pattern on the printing paper is transferred to the required medium. The thermosetting transfer method refers to the use of thermosetting ink (also known as hot melt adhesive) After printing into printing paper by silk screen, the pattern on the printing paper is transferred to cultural shirts and clothing. The two printing methods have obvious differences in application. The sublimation transfer method is mainly used in chemical fiber fabrics and coated with heat. On the hard material of the transfer coating, the thermosetting transfer method is mainly applied to pure cotton products. The difference in texture between the two printing methods is that the sublimation (used in the model gallery) does not change the original texture of the material after the pattern is transferred, and it has a good feel and feel. After the transfer of the thermosetting pattern, a layer of gel is formed on the surface of the attachment, which has a poor hand feeling and is not breathable. The two printing methods have their own advantages and disadvantages in production.
2. What is thermal transfer: Generally speaking, thermal transfer is a transfer technology and product. It uses a thermal transfer device (used in the model library) to heat the patterns and images on the thermal transfer paper to 180C0- -230C0 transfer printing technology on different materials and media, thermal transfer technology was first used in textile printing and dyeing industry, shoe material industry.
Later, with the development of the times and the advancement of science and technology, the application fields continued to increase, especially the emergence of digital technology and the emergence of personalized consumption concepts, making the application of thermal transfer technology more popular and extensive, and the application products emerged endlessly, covering almost all material fields. . Such as: metal, wood, stone, ceramics, glass, PVC, leather, chemical fiber fabrics can use thermal transfer technology to transfer beautiful patterns and images to produce and produce beautiful products.
3. Several technical methods of traditional sublimation thermal transfer There are three technical methods of traditional sublimation thermal transfer: silk screen thermal transfer, gravure (copper, electric engraving) thermal transfer, and offset thermal transfer. The traditional sublimation thermal transfer is characterized by plate printing.
4. Digital thermal transfer Digital thermal transfer is a new technology (second-hand model library) used to print pattern images in the form of unprinted printing on the basis of traditional sublimation thermal transfer combined with digital printing. Its characteristic is that because it uses digital printing technology to print color patterns and images without plate-making, it saves the plate-making process and cost, so it is suitable for producing personalized products for printing.
The technical feature of digital thermal transfer is that digital printing equipment uses special thermal transfer color printing ink and thermal transfer printing paper.
How to understand and understand digital thermal transfer technology
1. What is digital thermal transfer technology: Digital thermal transfer technology is a new technology that combines traditional thermal transfer technology and digital printing technology to print color images and patterns without plate-making (second-hand model gallery) Surgery. Initially, this technology was mainly used in the production of advertisements, signs, cards, and ceramic images in China. Later, with the expansion of the application field, it was more used in industrial production, such as digital printing and dyeing, clothing production, shoe material production, In the industrial production of webbing and clothing labels, the number of applied products is increasing.
The earliest countries to apply this technology are the United States, South Korea, Italy (used model library), Switzerland, China and other countries. In terms of the scale of the market in the past two years, China has become the world's largest digital thermal transfer processing market.
Many international thermal transfer color (second-hand model gallery) color printing ink brands have begun to target the huge Chinese market and participate in market competition. There is a looming trend of competition. The competition will become increasingly fierce. Here, we have to talk about The digital thermal transfer is based on inkjet printing technology as a technical form of digital thermal transfer, because this technical form can ensure a certain width and fixed length, suitable for industrial production.
2. The market significance of digital thermal transfer technology: digital thermal transfer technology can be said to be a new technology that emerges in order to adapt to the development of personalized markets and consumers' demand for personalized products. An effective supplement to the traditional thermal transfer product market. Therefore, strictly speaking, digital thermal transfer technology and product market positioning are personalized product markets. Traditional thermal transfer products are difficult to produce small batches of personalized products due to technical limitations and plate-making costs.
Therefore, in the traditional thermal transfer market, in terms of personalized products, digital thermal transfer technology is a market gap before the emergence. The emergence of this technology makes it possible to produce personalized thermal transfer products. Not only that, the printing quality of the image patterns of digital thermal transfer products also far exceeds the traditional thermal transfer technology. This is why digital thermal transfer technology can be promoted and popularized in just a few years.
