Dye sublimation ink is the ink consumable used in the sublimation transfer process. The ink is printed on special paper, and by heating, the image can be made into delicate porcelain, metal, silk, chemical fiber cloth and other materials in the shortest time. The color is vivid, the image is clear, and it can be saved forever, which is very suitable for the market needs of personalized development. It has a wide range of applications in the textile printing industry, such as clothing printing and dyeing factory proofing. Large-scale digital inkjet printing system, color map thermal transfer banner, advertising flag, etc., more applications in sublimation printers and direct sublimation printer.
Sublimation dye ink is mostly formulated from disperse dyes for textile use. Due to its saturated color and good weather resistance, disperse dyes have a wide range of applications in textile printing and dyeing, and are still one of the main raw materials for the printing and dyeing industry. With the advancement of science and technology, dye inks are becoming more environmentally friendly and more secure to use.
Sublimation ink is mainly used to transfer images to products through the characteristics of thermal sublimation, so the color reduction rate is more important. Generally, the reduction rate of high-quality ink can reach 90%, and the image on the heat transfer paper after transfer is basically close to white. So the color saturation of the image is very good, and the color is brighter.
Second, the size of the dye particles also determines the quality of the ink. The heat transfer ink with large particles is easy to cause the phenomenon of plugging the printer, and the image of the product produced is not delicate enough. When viewed with a magnifying glass, the granular shape can be clearly seen. In general, the sublimation ink particles of lower quality are larger than the particles of the high-quality sublimation ink, which results in the printer not being fine enough to print and transfer images.
The last question should be encountered by everyone. Some inferior sublimation ink blacks are red and purple. For thermal transfer inks, black ink is the most easily color cast, so you can first print a black color block to transfer when you choose, to see if the color after transfer is black. This is also an important indicator that directly distinguishes the advantages and disadvantages of heat transfer sublimation inks.
