Digital Thermal Transfer, Digital Sublimation, Digital Direct Printing, Understand Their Differences

Digital thermal transfer technology is a new technology that combines traditional thermal transfer technology and digital printing technology to print color images and patterns in a plateless form. In China, this technology was mainly used in the production of advertisements, signs, cards, and ceramic images. Later, with the expansion of the application field, it was more applied in industrial production, such as digital printing and dyeing and clothing production, shoe material production, In the industrial production of webbing, clothing labels, etc., the number of applied products is increasing.

Here, the digital thermal transfer printing we are going to talk about is digital thermal transfer printing with inkjet printing technology as a technical form, because this technical form can guarantee a certain width and fixed length, which is suitable for industrial production.

At present, thermal sublimation, heat-set transfer and inkjet direct printing are called digital printing, and all three are new technologies that have emerged to adapt to the development of the personalized market and the needs of consumers for personalized products. Dye sublimation and thermoset transfer appeared earlier, and inkjet direct printing is still in the promotion stage in China.

How does sublimation technology work?

The working principle of thermal sublimation is: disperse dyes have the characteristics of sublimation at a certain temperature! The ink or ink containing dye is printed on the transfer paper, and then the transfer paper printed with the pattern is in close contact with the fabric, and the dye is transferred from the printing paper to the fabric under the control of a certain temperature, pressure and time. After diffusion, it enters the interior of the fabric, to achieve the purpose of coloring. In terms of technology, there are three types of traditional sublimation heat transfer: silk screen heat transfer, gravure heat transfer, and offset heat transfer.

The consumables used for sublimation are Sublimation ink, that is, sublimation ink. After being heated and transferred by a thermal transfer machine, the basic requirements are that the image is clear, the color reproduction degree and the washing fastness are high.

Application of dye sublimation technology

The sublimation transfer method is mainly used on chemical fiber fabrics and hard materials coated with thermal transfer coating. The color performance is perfect, the transition is natural, high-precision printing is achieved, and it is comfortable to wear, but it requires more complicated processes such as steaming and washing. Printing and dyeing washing and drying equipment, reasonable steaming equipment and working space, so there are certain technical and investment restrictions on homework. At the same time, thermal sublimation uses chemical consumables that are harmful to human body, and at the same time, the above-mentioned treatment process will produce a lot of waste water and waste liquid, so it is not environmentally friendly.

For pure cotton, it is mainly thermosetting transfer printing and digital inkjet direct injection. After the heat-setting pattern is transferred, a layer of glue is formed on the surface of the attachment, which has a poor hand feel and is not breathable. When it is used for dark pure cotton printing, there are many restrictions and it is difficult to promote!

Digital direct injection is the most cutting-edge printing solution launched to solve the problem of pure cotton printing, and it is also the printing method adopted by domestic leading textile manufacturers to change their business concepts!

Connect the computer equipment to the printing machine via USB, and what you see on the computer is what you get. The printing quality is outstanding, the layers are rich, and the color gradient is natural. Due to the use of consumables that do not contain any chemical ingredients, it meets the standards of the new concept of environmentally friendly clothing, adapts to the manufacturing industry with low cost and cheap labor as its main advantages, and focuses on research and development, from production efficiency to brand efficiency, with high added value. The world trend of new manufacturing transformation.
