Interpretation:Thermal transfer process of digital printing machine
What is the thermal transfer process?
The thermal transfer process in the digital printing machine is a process technology that uses dot printing (with a resolution of 300 DPI) to pre-print the pattern on the surface of the film and then transfer it on the surface of the product. The patterns formed by this printing are rich in layers, bright in colors, ever-changing in patterns, and small in color difference, which greatly improves the grade of products, can meet the requirements of customers for patterns and colors, and is suitable for mass production.
Classification of thermal transfer process in digital printing machine
Among digital printing machines, clothing thermal transfer is the most widely used, but the common thermal transfer methods are mainly the following two:
(1) Sublimation thermal transfer
To put it simply, sublimation thermal transfer printing is to print the disperse dye on a specific paper in advance by the machine, and then use this paper to transfer the pattern to the fabric with high temperature and high pressure to complete the entire thermal transfer printing process.
(2) Thermal transfer heat transfer
Unlike the sublimation thermal transfer printing method, the printed material does not have a sublimation effect like the sublimation dye. The printed material will not penetrate into the fabric fiber under high temperature and high pressure. Although it can also be pressed with a transfer machine, it is just attached to the surface, which not only has a poor hand feel, but also greatly reduces the breathability of the clothes.
Advantages of thermal transfer process
(1) Simple printing
Only one computer and one operator can complete the printing operation. The method is simple and desirable.
(2) Accurate location
The thermal transfer process avoids the position shift problem that is easy to occur in the manual printing process, and can accurately align the area and position to be printed. At the same time, because it is a one-time printing, it also avoids the problem of color registration and registration. The patterns produced are exquisite and the picture quality is more precise and excellent.
The thermal transfer process of the digital printing machine can solve the process problems of the material at one time, and realize that any object can be printed, so the digital printing machine of the thermal transfer has also become a universal printer.
As long as a computer, a printer equipped with thermal transfer ink and a heat press machine can print images on any solid object or any curved surface, the pattern is clear, the color is bright, the effect is realistic, and the adhesion is super. Strong and other characteristics. Can accept all kinds of personalized customization, on-site production, widely used, everywhere! This is also the reason why thermal transfer is a favorite.
