Stenter was mainly introduced into China from abroad in the course of his work, and his introduction time was only more than 10 years.

In my country, although the thermal transfer technology in digital printing machines is a new printing process, once this technology is introduced, it immediately becomes the darling of the domestic printing industry.

What is the thermal transfer process of digital printing machine?

The thermal transfer process in the digital printing machine is a process technology in which dot printing (resolution of 300DPI) is used to pre-print the pattern on the surface of the film, and then transfer it on the surface of the product. In this way, the printed patterns are rich in layers, bright colors, ever-changing patterns, and small color difference, which greatly improves the grade of the product, can meet the customer's requirements for patterns and colors, and is suitable for mass production.

Classification of thermal transfer process in digital printing machine

In digital printing machines, clothing thermal transfer is widely used, but the common thermal transfer methods mainly include the following two:

(1) Sublimation heat transfer

Simply put, sublimation thermal transfer is to print disperse dyes on a specific paper in advance by a machine, and then use this paper to transfer the pattern on the paper to the fabric to be printed by using high temperature and high pressure to complete the entire thermal transfer printing. process.

(2) Thermal transfer heat transfer

Different from the sublimation heat transfer printing method, the printing material does not produce sublimation like sublimation dyes. The printing material will not penetrate into the fabric fiber under high temperature and high pressure. Although it can also be pressed by a transfer machine, it is printed on clothing. The upper is only attached to the surface, which not only has a poor hand feel, but also greatly reduces the air permeability of the clothes.

The thermal transfer process does not require the steps of plate making, printing, and repeated color registration. It does not require various types of tools and materials required by screen printing and transfer methods. It only needs a computer and an operator to complete the printing operation. The method is simple and desirable.

The thermal transfer process of Flat Screen Printing Machine avoids the problem of positional deviation that is easy to occur in the manual printing process, and can accurately align the areas and positions that need to be meaningful. At the same time, because it is a one-time printing, it also avoids the color matching. Because of the problem of position, the printed patterns have delicate transitions and more accurate picture quality.
