However, compared with the traditional 2D glass, the 3D glass has an uneven surface, the traditional silk-screen coating process is not applicable, the pad printing and spraying process is used as a substitute, the pad printing process is particularly suitable for printing on the surface of an irregular object, the efficiency is high, the environmental pollution is less, and the like, and the pad printing process is more and more emphasized in the field of 3D glass, so that the ink for the pad printing of the 3D glass of the mobile phone has huge market demand. The traditional plastic pad printing ink cannot be directly used in the field of mobile phone 3D glass, because mobile phone 3D glass printing has higher requirements on the ink, preferably, the glass surface tension is low, and the requirement on the printability of the ink is higher; secondly, the glass surface has high hardness, is corrosion resistant and is not easy to adhere, and also puts higher requirements on the adhesion and the resistance of the printing ink.
Therefore, the existing pad printing ink is to be perfected and developed.
