In the daily work, they often encounter the same pattern of ink and printed water-based prints. In this case, it is not worthwhile to make two screens (water-based, oily). If you use oil-based printing paste or water-based printing solvent ink, there is no service life for the plate. Here the author introduces you to a simple solution.
The basic method is to mix water-based and oil-based photosensitive adhesives, and the mixing ratio can be flexibly controlled. Generally, they account for 50% each. If the oily life is high and the water-based activity is low, the proportion of oily photosynthetic rubber may be larger, and vice versa, the maximum proportion should be controlled between 35% and 65%. This version is better off after use, if you want to extend the life of the version, the same curing with a hardener or strong ultraviolet light, you can make the screen more durable.

How can we reach a High Hardness Carton?
1. The thickness and material are two key factors that determine the hardness of the Carton
High-hardness cartons usually have three or five carton boxes, and of course, there are seven thicker ones. The more carton layers are thicker, the third and fifth floor cartons are also listed with corrugated and double corrugated cartons. There are also various carton materials. Good materials are not only high in hardness, but also light in weight. Materials that are poor are often very low in hardness and are easily deformed. The material of cartons on the market is "KK>KA>KB>AA>AB>BB", KK It is the best material at the moment, but the price is also the most expensive.
2. Achieve high hardness carton can also use ordinary cardboard to strengthen the core treatment, plus hard surface treatment.
I suggest that sellers choose different types of cartons according to their needs. For example, fragile, valuable items can be used with five-layer AA cartons, ordinary items that are thrown, or the product itself comes with a Paper Box. Choosing three layers is enough.
