The essence of the glazing coating process during clear tube printing is the process in which the glazing coating is leveled and dried on the surface of the print. The main influencing factors are the glazing suitability of the printed matter, the type and performance of the glazing coating, and the coating processing conditions.

The print is glazed on the cosmetic tube. It refers to the influence of the performance of printed paper and printed graphics on glazing coating. In glazing coatings, glazing coatings tend to level on highly smooth paper surfaces. In the drying process, as the glazing coating is cured, a smoother film surface can be formed, so the higher the surface smoothness of the paper, the better the glazing coating effect, and vice versa.

The surface of the paper is too absorbent, the absorption rate of the paper fiber to the glazing coating is high, the solvent penetration is fast, the viscosity of the coating becomes larger, and the shear stress of the coating layer flowing on the surface of the printing material increases, which affects the leveling of the glazing coating. It is difficult to form a smoother film layer; on the contrary, the absorption is too weak, so that the penetration, solidification and conjunctiva of the glazing coating in the leveling are significantly reduced, and a high-quality film layer cannot be formed on the surface of the printed matter.

The quality of the printed ink also directly affects the coating quality and leveling properties of the glazing coating. The particles of the ink are fine and the dispersion degree is high, and the ink layer of the ink is easily wetted by the glazing paint. Under the application of the coating pressure, the leveling property is good, and the smoothness of the formed film layer is high. On the contrary, the film quality is poor.
