Specific uses of thermal transfer film

Thermal transfer processing is a new method of printing patterns on products made of various materials. It is especially suitable for producing small quantities of various personalized and customized products, as well as printing patterns containing full-color images or photos.

The principle is to use a printer to print a digital pattern on special transfer paper with special transfer ink, and then use a special transfer machine to accurately transfer the pattern to the surface of the product under high temperature and high pressure to complete the product printing. Thermal transfer processing technology can also use a variety of different transfer materials to achieve different printing effects. The most important ones are film transfer and sublimation transfer.

The transfer paper for film transfer contains colloid, and then the colloid pattern is printed on the surface of the product using high temperature and high pressure. Using high-quality imported transfer paper and ink, the printed gel pattern is very thin, breathable, non-sticky, non-cracking, washable and does not fall off; unlike many domestic transfer papers used in the market,

The printed gel pattern is thicker and often has the disadvantages of sticking and cracking. Sublimation transfer is a new generation technology that uses special sublimation ink and sublimation transfer paper. When the pattern is printed on the product, no colloid will be produced. If it is transferred to clothing, the ink will be directly sublimated into the clothing fibers. The fastness is the same as cloth dyeing, and the color is sharp, which is more suitable for colorful patterns.

Heat transfer printed products Not all products can be printed with heat transfer printing, which involves factors such as the heat resistance and smoothness of the product. Due to the continuous advancement of technology, products that have been maturely developed using heat transfer printing technology include: clothes, cloth bags, hats, pillows, mugs, tiles, watches, mouse pads, coasters, hanging calendars, and medals , banners, and hundreds of other products. (1) Sublimation transfer printing: The current technology is mainly applicable to clothes with polyester fiber (polyester) on the surface, such as quick sweat-wicking shirts and physical comfort shirts, and white clothes are preferred (the printed pattern is white, but the clothes Other parts can be other colors, such as colorful sleeves). After colored clothes are digitally sublimated, the ink is fused with the colored fibers.

  It will make the color of the pattern different from the original, so it is not recommended. (2) Film transfer: The current technology is mainly used for clothes with high cotton content. All colors can be film transferred, but dark clothes require the more expensive "transfer paper for dark clothes", which has heavier glue and less stable quality. Transfer printing of ceramic products Ceramic products use sublimation transfer printing. At a high temperature of about 200 degrees Celsius, the ink is sublimated onto the product. The color is sharp and the pattern is highly reliable. However, ordinary mugs cannot be transferred directly. They must undergo a special coating process before the pattern can be transferred.
