Excessive dusting amount is harmful to the printing process

1. When the amount of powder is too large, when positive and negative printing is performed, the amount of powder on the front side is too large, which will directly affect the output of the class on the reverse side. In severe cases, it takes a few hundred sheets to clean the blanket. The product will also appear unstable ink, affecting quality and affecting yield.

2. Too much powder will affect the gloss of the product. When printing some high-end products, the operator always hopes that the ink color saturation is higher. The products printed in this way are both bright and shiny, and at the same time they increase the amount of powder in order to prevent dirt. The dusting is absorbed by the ink on the ink layer that has not been dried, and a layer of fog is formed on the color, and the gloss of the product is reduced accordingly.

3. The amount of powder is too large and the wear on the machine equipment is severe. In production, while spraying powder, a considerable part of the powder goes to the machine's delivery chain, grippers, and rollers. Although there is maintenance time every week, it may not be able to clean up all the dust. It will inevitably increase the wear on the machine over time.

4. The amount of powder is too large and it will have a certain influence on the health of the operator. Although sellers say that dusting is harmless to the human body, the operator stays in the dusty workshop every day and the lungs do not know how much dust to inhale.

5. The amount of powder is too large, it will also affect the post-process processing, such as light coating.

Therefore, in the production, we should pay enough attention to the amount of dusting, spraying or spraying as little as possible to achieve the purpose of controlling the dirt on the back. There are many factors that cause back-scratching in production. The key is how to effectively control it.
