For book printing in China, eco-friendly printing refers to a printing method that uses environmentally friendly materials and processes, produces less pollution during the printing process, saves resources and energy, and is easy to recycle after the printed matter is discarded, can be naturally degraded, and has a small impact on the ecological environment.
For the book printers in China, eco-friendly printing requires that the Chinese book printing process should be coordinated with the environment, including the use of environmentally friendly printing materials, a clean printing production process, the safety of printed materials to users, and the recycling and recycling of printed materials. That is, the entire life cycle of printed matter from raw material selection, production, use, and recycling should meet environmental protection requirements.

What are the characteristics of eco-friendly printing?
Reduction and moderation, non-toxic and harmless, pollution-free are the three main characteristics of eco-friendly in Chinese printing.
Reduction and moderation:
In Chinese book printing processes, reduction and moderation refer to moderate in book printing with the least amount and the most simplified process under the conditions of meeting the functions of information identification, protection, convenience, and sales.
