White ink heat transfer is a new type of printing process, which has become popular all over the world in only three years since 2019, occupying a very important position in the printing industry. So, is white ink heat transfer really that good? Compared with the traditional printing process, how about the color fastness of white ink heat transfer? There are three major factors in the color fixing of the white ink heat transfer process: high-quality ink, color fixing temperature and color fixing time. Today TEXTEK will give you a detailed explanation:
1. High quality ink
The ink quality of white ink heat transfer is very important for fixing the color. The inks of digital heat transfer printing machines on the market are also uneven. Important role can directly affect the washing color fastness of printing.
2. Fixing temperature
It takes many tests to master the temperature of the fabric before it can really fix the color. Different fabrics, different inks, and different processes have different color-fixing temperatures. The temperature is too low and useless. Too high can easily damage the fabric. The ideal fixing temperature is Not only can it ensure good color fastness, but also does not affect the feel of the fabric.
3. Fixing time
According to the actual fabric of the equipment, the fixing time depends on the fixing temperature and equipment. The lower the temperature, the longer the fixing time, and the higher the temperature, the shorter the fixing time. Different equipment, even at the same temperature, has different fixing time. For example, the fixing time of oven must be longer than that of pressing machine and tunnel furnace, because it should be considered that there is a heating process from normal temperature to high temperature, which takes time.
