DTF transfer is a new type of printing process, which has become popular all over the world since 2019 and occupies a very important position in the printing industry. So is dtf transfer really that good? Compared with the traditional printing process, how is the color fastness of dtf transfer? There are three major factors in the color fixing of dtf transfer technology, high-quality ink, color fixing temperature and color fixing time.

1. High quality ink
The quality of dtf ink is very important for color fixation. The inks of digital heat transfer printing machines on the market are also uneven. Expensive inks are not necessarily good, but the quality and fluency of inks play a vital role in the printing effect. The effect can directly affect the color fastness of printing to washing.

2. Fixing temperature
The color can be really fixed only by mastering the temperature of the fabric through multiple tests. Different fabrics, different inks, and different processes have different fixing temperatures. If the temperature is too low, it is useless, and if the temperature is too high, it will easily damage the fabric. The ideal color fixing temperature Not only can it ensure good color fastness, but it will not affect the feel of the fabric.

3. Fixing time
According to the actual material of the equipment, the color fixing time depends on the color fixing temperature and equipment, the lower the temperature, the longer the color fixing time, and the higher the temperature, the shorter the color fixing time. Different equipment, even at the same temperature, has different color fixing time. For example, the color fixing time of the oven must be longer than that of the press machine and tunnel furnace, because it has a heating process from normal temperature to high temperature, which takes time.
