Several Elements that Affect the Quality of Sublimation Transfer Printing

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.

1.The ink

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.

3.The pressure

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.

Solutions for Some Common Issues in Sublimation Printing

   In sublimation printing, people may meet all kinds of problems in the whole process. For some problems, we must need professional technicians to help us. But for some problems, we can solve it by ourselves easily. Here we list some easy problems you may encounter.

   1. The color is not bright after transfer printing
   We can often see this problem when printing. The images printed on the sublimation paper bright, but after the transfer printing, the color is not as bright as before.Temperature is too low, the pressure is uneven or the time is too short all can lead to this problem.

   2. The imageis not clear at all
   If the time is too long when transfer printing, the ink will be spread, and then the image will be blurry.

   3. The images are matte after printing.
   High pressure or high temperature will always lead to this problem. Pay attention to control the pressure and temperature is very important.

   4. The color of the image is uneven.
   Sometimes the color of image is uneven after printing, and the printing product looks so ugly. Uneven pressure or the uneven coating on the substrate can be the main reasons for this problem.

   5. The image on the substrate is easy to fade.
   This is a terrible problem. Customers will never receive the faded products. If you meet this problem, please turn up the temperature or spend more time on printing.

   Of course we just list some problems we often meet , and there are many other problems we can solve by ourselves. If you have some good tips, welcome to share with us.
