Color difference in gray color pulp
Reason analysis: The density of black molecules is relatively high, and prolonged placement will cause sedimentation, resulting in color differences. Solution: Please stir thoroughly before use to ensure even dispersion and avoid color differences.

The quality of the ink directly affects the quality of packaging printing
Ink is the main raw material for printing. Only by thoroughly understanding the structure and working principle of ink can high-quality prints be produced. In order to meet product quality requirements, printing plants must have a detailed understanding of ink properties when using ink to ensure that the printed products meet printing adaptability and various testing indicators. The main components of ink are colored pigments and binders. The colored pigments play a color-rendering role, forming a contrast with the color of the substrate to show the image on the substrate. Only by correctly understanding and recognizing the ink and adjusting the proportions of the various components of the ink can the ink achieve its required printability and usability.

How to determine if UV ink is cured?
Four methods to determine if UV ink is completely cured after UV lamp irradiation: 1. Pencil hardness test All UV ink technical conditions include pencil hardness. According to this requirement, we can use a pencil hardness tester. If the requirement is met (generally 3-4H), it proves that the ink is completely cured. 2. Solvent dripping method test As mentioned above, the technical conditions of UV ink also include solvent resistance. Because after the ink is completely cured, the internal molecular structure will change, converting to double bonds. The higher the conversion, the more complete the curing, and the overall shape of the ink will change accordingly.
