2025,06,20
Today, with the digital technology sweeping the world, ink printing still maintains irreplaceable cultural value. This ancient technique, which originated in the Sui and Tang Dynasties in China, achieved the most lasting media revolution in the history of human civilization communication through the physical process of transferring ink to the substrate.
Modern ink printing has developed four mature processes. Offset printing occupies a dominant position in the field of book printing by virtue of the principle of ink balance; Gravure printing is the first choice for packaging and printing because of its excellent ink layer thickness; Flexographic printing shines brightly in the field of food packaging because of its environmental protection characteristics; Screen printing is unique in special printing because of its unique principle of missing printing. Behind each process, the wisdom crystallization of material science, fluid mechanics and chromatics is condensed. The evolution of ink itself is equally amazing. From traditional solvent-based inks to environmentally friendly water-based inks, from UV-curable inks to temperature-sensitive anti-counterfeiting inks, every formulation innovation has promoted the leap of printing quality. Especially in the field of security printing, the application of magnetic ink and OVI optically variable ink makes the anti-counterfeiting technology of paper money achieve the perfect integration of art and technology. When we stare at rare ancient books in museums, choose exquisite packages in supermarkets, or take out banknotes from wallets, ink printing technology is continuing the mission of civilized communication in a silent and elegant way. This process, which has evolved for thousands of years, is still absorbing new technologies and continuing to write a new chapter in human information dissemination.
