Packaging printing is a production technology that uses packaging materials as a carrier to reproduce images and text through processes such as letterpress, offset, gravure, screen printing, and digital printing. It serves both decorative and informational functions, encompassing surface treatments of materials such as paper, plastic, and metal. Its core elements include ink, color management, and environmental considerations. Common processes include four-color printing, spot color printing, gloss lamination, and hot stamping, while also balancing economic efficiency and production efficiency.
Printing technology is the technology of reproducing graphic information, and printed materials are information carriers for disseminating scientific and cultural knowledge. The characteristics of packaging printing are twofold: first, its reproducibility-the printing industry is a special processing industry whose task is to reproduce the graphic information in the original manuscript, which is the basis and foundation of the printing operation; second, its artistry-printing is a crystallization of technology and art, and has always been recognized worldwide as a "sacred art" and the "mother of civilization." The process of reproducing the original manuscript is also a process of artistic processing. Printing professionals should possess a certain level of artistic appreciation ability, accurately grasping the artistic characteristics and style of the original artwork, employing appropriate reproduction methods and techniques to reproduce its charm, and enhancing its artistic expression through image processing. Environmental protection is a fundamental national policy of my country and an important guarantee for implementing the sustainable development strategy and achieving modernization. As a modern service industry, packaging and printing should place even greater emphasis on environmental protection and strictly implement environmental protection plans in accordance with relevant national regulations.
This technology has formed a complete industrial chain alongside the development of the industrial system. Offset printing remains dominant due to its ease of plate making, flexographic printing has achieved technological breakthroughs through environmentally friendly solvents, and gravure printing is suitable for long-term mass production. New technologies such as digital printing and inkjet printing are driving the upgrading of equipment towards automation and intelligence.
