What are the reasons and solutions for blurred edges of printing patterns in textile thermal transfer printing?

Patterns are common in daily necessities, wearables, decorative items, works of art, etc. One is for the beauty of the items, and the other is because people have different needs. With the development of our country and the increase in people's vision, textile heat transfer printing Processing printing uses this technology on most supplies.

The products of this technology are rich in color and lifelike, but we have seen that the edges of the patterns printed by some manufacturers vary from clear to blurry. So what is going on? How to deal with it? The main reason lies in its production process: since the fluidity of the slurry is relatively good at the beginning of printing, the scraper does not need a lot of force to cut the slurry cleanly, but as the glue becomes thicker As the water continues to evaporate, the slurry will gradually thicken and its viscosity will gradually increase.

In this way, it is necessary to increase the particle size of the scraper to cut off the excess slurry. It is also because the increase in strength causes the elastic deformation of the screen, resulting in displacement of the pattern. As the force of the scraper increases, disappear, and after the screen rebounds, the edges of the pattern on the screen printing surface will stick to the paste. When printing again, the paste will move to the edge of the pattern, which will cause the edge of the pattern to be blurred. The pattern is blurred due to mutual bleeding.
