The traditional sublimation transfer printing refers to printing the sublimation transfer ink on paper (or plastic film) by screen printing, and overlaying the printed paper (or film) with the fabric, heating, pressing or subtracting When pressed, the dye on the paper (or film) is sublimated and transferred to the fabric in the gas phase. In addition to fabrics, it can also be transferred to ceramics, metals and other products. The main feature of the sublimation transfer technology is that the transfer image is bright in color, rich in layers, and the effect is comparable to that of printing. The difference with printing is that the dye in the transfer ink is sublimated by heat, penetrates into the surface of the object, and forms a bright image after sublimation. Therefore, the heat transfer product is durable, and the image will not fall off, crack and fade.
With the rapid development of high technology, thermal transfer technology and level have also been further expanded and improved. Thermal transfer technology widely uses computers for image processing and design, and then prints images on paper through high-speed and high-quality inkjet printers (Or film), eliminating the need for the plate making process, and can also coat the sublimation ink on the plastic film and cut into ribbons for use in the printing technology of smart cards.
