Mirror inks are heard by many people and are not very familiar to them. What are the specific usage caution methods?
Mirror inks are special effects. It is printed on the transparent material by the reverse side to obtain the best mirror effect on the front side.
We will explain the following how to use mirror ink:
1. First of all, it should be understood that the mirror ink is as thin as water. The printing technique is the key. When the printing speed is slow, the surface ink will leak under the screen. On the other hand, the mirror ink can easily absorb the moisture in the air. After the mirror surface effect is not good, for this reason, in the screen printing mesh, the mirror ink must be continuously and quickly printed after being poured into the screen to complete the smooth printing, that is, the speed of checking the workpiece while printing will affect the printing effect. For example, blocking the net, the ink can not be printed, in the screen, the slag group and so on.
2, the temperature and humidity of the printing mesh mirror ink is very important, because the ink is easy to dry on the screen, so you can not screen under the air circulation, otherwise it is very easy to block the net, when the air humidity is high, the mirror effect is poor, so When screen printing, avoid air flow and moisture as much as possible.
3, because the ink is as thin as water, so you should choose high mesh screen, not only that, the hardness of the squeegee should be harder, more than 80 degrees.
4, the tension of the screen printing mesh is slightly lower, the mesh distance is also adjusted closer, and the scraping pressure of the scraper is appropriately reduced, otherwise the formation of the mirror effect will be destroyed.
5. The mirror ink must be fully stirred before use, so that the aluminum powder and the resin should be fully mixed evenly to ensure the appearance of the mirror effect. Otherwise, the mirror effect will be affected.
