Sublimation Transfer Printing-Do You Know What Factors Affect Its Quality?

In the sublimation transfer printing process, there are many factors that affect the quality of printing. Here are some of the main reasons to affect it.

1.What is dye sublimation printing?

Sublimation Transfer Printing

Dye sublimation printing, is a printing method for transferring images onto a substrate (usually a cloth material such as polyester). Sublimation refers to a process where a substance moves from a solid to a gas state without ever being in a liquid state. Textile sublimation printing normally involves the use of a digital printer to produce mirrored images on paper that has been specially coated with a transfer material.

2.What are the elements that affect the quality of inkjet sublimation printing?

(1).The ink

The sublimation ink is the key material digital sublimation 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 dye sublimation printing ink is the key material digital sublimation 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 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.

The above is the most important reason that affects the quality of sublimation transfer, so we should try to avoid it in the transfer process to achieve better transfer results.
