To make a green road to offset printing, you must first know what green printing is.
1. The concept of green printing
Green printing refers to the use of environmentally friendly materials and processes that produce less pollution during the printing process, save resources and energy, and are easy to recycle and reuse after printing, can be naturally degraded, and have a small impact on the ecological environment. Green printing requires coordination with the environment, including the use of environmentally friendly printing materials, clean printing production processes, the safety of prints to users, and the recycling and recyclability of printed materials. That is, the entire life cycle of the printed materials, from raw material selection, production, use, recycling, etc., should meet the requirements of environmental protection.
2. The connotation of green printing
Green printing is universally recognized by all countries in the world. It is a descriptive and descriptive term for two core connotations and attributes that are environmentally friendly and healthy. Green printing refers to the use of environmentally friendly materials and processes, resulting in less pollution and savings in the printing process. Resources and energy, printed materials that are easy to recycle after recycling, can be naturally degraded, and have little impact on the ecological environment. Not only reflects the concept of sustainable development, people-oriented, advanced science and technology, but also an important means to achieve energy-saving emission reduction and low-carbon economy.
The green printing industry chain mainly includes green printing materials, printing graphic design, green platemaking technology, green printing technology, green post-printing processing technology, environment-friendly printing equipment, and print waste recycling and recycling. Through the implementation of green printing, the entire supply chain system including materials, processing, application and consumption can be brought into a virtuous cycle.
3. The scope of implementing green printing
The scope of the implementation of green printing includes printing production equipment, raw and auxiliary materials, production processes and publications, packaging and decoration and various types of printed matter, involving the entire process of production of printed products.
The production equipment for implementing green printing covers printing production equipment involved in printing processes using offset printing, letterpress printing, gravure printing, aperture printing, digital printing, and combination printing.
The scope of green printing for lithography is the use of lithographic printing processes and printed products. Printing methods are single-sheet lithography and rotary lithography. The printed products mainly include card books, hardcover books, glue books, gift boxes, paper bags, greeting cards, magazines, newspapers and so on.
