The technology of sublimation heat transfer paper originated in developed countries such as Europe, the United States, and South Korea. In recent years, due to the strong domestic market demand, my country seems to have become the world's largest consumer and production and processing place for thermoelectric products. In the thermoelectric company's technology, thermoelectric paper is one of the important consumables in the process of use. About 1,300 tons of thermoelectric paper are imported from my country every year. With the development of the thermoelectric company's technology and the extensive domestic market demand, the thermoelectric company's consumables products have attracted the attention of related domestic manufacturers.
The heat transfer printing technology of sublimation heat transfer paper prints a pattern on the heat transfer paper, and then applies a certain temperature and pressure to transfer the pattern to the printed matter. The heat transfer paper plays the role of a transcription carrier. Thermoelectric photographic paper can generally be divided into hot melt adhesive and thermal sublimation types according to the principle. The surface of hot melt adhesive thermal transfer paper is generally coated with hot melt adhesive, which is only used for printing pure cotton, silk, linen, and other characters. Dye-sublimation thermoelectric photo paper is a pre-made computer pattern, which is printed on the paper with an inkjet printer of special ink, and then the thermoelectric photo paper and the photo paper are superimposed together, and the ink on the paper is sublimated under a certain temperature and pressure, Sublimation weather state, forming a complete pattern continuously on the print.
What is the suitable ink for sublimation heat transfer paper?
For dye-sublimation photo paper, use dye-sublimation ink. Dye-sublimation ink (also known as dye-sublimation ink) can make low-energy, easy-sublimation disperse dyes into digital printing inks, which are printed on dye-sublimation photo paper, and the images are made into exquisite ceramics in the shortest time by heating. Metal, silk, chemical fiber cloth, and other materials meet the market requirements and environmental requirements of personalized development
Sublimation photo paper is suitable for cloth, leather, metal, wood, ceramics, glass, plexiglass, PVC board, etc.
Features: The printing image is bright in color, rich in layers, and has an effect comparable to printing. However, the difference is that thermal transfer is an image formed by heating the thermal transfer ink at a high temperature, subliming it, penetrating the surface of the medium, and solidifying it. Therefore, no glue film is formed on the surface of the medium, the image does not fall off, there is no crack, the light resistance is strong, and the color does not fade for a long time.
How does sublimation heat transfer paper identify paper impurity spots?
Spots (impurity spots) on the surface of cardboard are an important indicator of cardboard, which can occur on the base paper, or in the coating or production process. Spots seriously damage large-area monochrome printing, but have little effect on pattern printing. Domestic copy paper generally has speckle problems. A lot of research work has been done on spot removal, and a lot of efforts have been made in the generation and removal of spots. There are strict regulations and controls from base paper to coating formulation and production process, but there may still be 1 per square meter. ~ 2 spots.
