What are the basic elements that affect the quality of heat sublimation transfer ink?

Before we discuss today's problems, let's familiarize ourselves with what is heat sublimation transfer ink. Where is its application field?

Definition and characteristics

The sublimation transfer ink is called heat sublimation ink, also known as heat transfer ink. Is a low energy, easily sublimated disperse dye made into digital printing ink, printed on the transfer paper, by heating, in the shortest time can be produced in the shortest time image to fine porcelain, metal, silk, chemical fiber fabric and other materials. It is very suitable for personalized development of market needs and environmental protection requirements.

Several fundamental elements

1, temperature and time

The heat sublimation transfer process requires that the temperature be controlled in the range of 180 ~ 230 C, and the time is about 10 ~ 30s. At the same time, attention should be paid to the reasonable deployment of temperature and time.

2, ink

The key materials for sublimation transfer printing technology are mainly composed of disperse dyes, connecting materials, solvents and a small amount of additives. Dyestuff should have good sublimation, transferability and permeability, and achieve a certain fastness index. The molecular weight is 230~380 and the sublimation temperature is 180 ~ 240 C.

3, pressure

Pressure is also one of the important parameters of the sublimation transfer process. The heat transfer printing of fabric is taken as an example. If the pressure is too small, the gap between the fabric and the transfer paper is large, the yarn is round and the ink gas molecules collide with the air, and the printing effect is bad. At the same time, the ink is easily permeated and the line is thickened, and the pattern, the pattern is blurred and the visual effect is worse. If the pressure is appropriate, the yarn is flat and the gap between the transfer paper is suitable, so the transfer printing effect is good, the pattern is clear, and the lines are smooth and fine. If the pressure is too high, it is easy to produce deformation, fuzz and heavy fabric changes in shape and other problems, resulting in rough handle and coloring and surface defects. Therefore, controlling transfer pressure is very important for printing pattern, pattern clarity, visual effect and so on.

4, the other

Besides ink, temperature, time and pressure will affect the quality of sublimation transfer printing, there are still some matters worthy of our attention in the actual production process. For example, proofing before production, transfer paper selection and so on.

The choice of high quality sublimation ink can give a clearer digital print pattern. What do you think is a great increase in the quality of the product?
