In the actual production process,many negligent details may lead to defects in the quality of our products. What do we need to pay attention to when printing? Today, we will analyze several Fundamental Elements that affect the quality of sublimation transfer printing.
The sublimation transfer printing ink is the key material sublimation transfer printing technology. It is mainly composed of disperse dye, connection material, solvent and a small amount of additives. Dyes requires good sublimation transfer resistance and permeability. It has achieved the fastness. Sublimation temperature is 180-240 ℃, and suitable for printing.The sublimation transfer printing ink is the key material sublimation transfer printing technology. Sublimation temperature is 180-240 ℃, then will be suitable for printing. The heat sublimation ink color is clear with good quality, the stability is strong and the transfer effect is good. At present, the ink have 2 kinds-water-based and solvent-based. The solvent thermal sublimation ink is mainly used in wide spraying machine. It solves the problem of inkjet printing speed and width. The sublimation ink quality directly affects the quality of the product. Therefore, choosing high quality thermal sublimation ink is very important.
2.The temperature and time
The temperature and time thermal sublimation transfer printing technology is to control the temperature of 180 ~ 230 ℃ range. Transfer time is about 10-30s. At the same time also pay attention to the temperature and the reasonable allocation of time.
Pressure is also one of the important parameters of heat sublimation transfer printing technology. For example, if the pressure is too small, big gap will occur between fabric and transfer paper, then will occur yarn assumes the circular, ink gas molecule collisions with a lot of air and dissipation. It will lead to poor effect, also easy to ink bled, line coarsen and decorative pattern design, fuzzy, visual effect is worse. If pressure is appropriate , yarn is flat, and appropriate gap between transfer paper and transfer printing fabric shading effect will be good. The pattern is clear, smooth fine lines. If pressure is too large, it will prone to deformation, burr and morphological changes in thick fabric, shortcomings and so on superficial feel hard and staining.
Of course, in addition to ink, temperature, time and pressure will affect the quality of the sublimation transfer printing,there are some other issues worthy of our attention. Our company has sublimation transfer paper, ink, printer and other accessories in sale. If you have any demand, please feel free to contact us.
