The hottest new way to solve printing pollution

New principles to solve printing pollution

the executive vice president of the Chinese Academy of Sciences has no obvious defects such as burns on the surface of steel bars. Academician Bai Chunli revealed in an interview in Han yesterday that the green printing technology invented by the Chinese Academy of Sciences is expected to replace the Laser Phototypesetting Technology and realize the third printing revolution since the invention of movable type printing technology

this new technology, named green printing and plate making technology of nano materials, was invented by scientists from the Institute of chemistry, Chinese Academy of Sciences. At the beginning of this year, the pilot test of this technology has begun

Bai Chunli pointed out that the laser Phototypesetting Technology of Chinese characters invented by Academician Wang Xuan made the Chinese printing industry bid farewell to lead and fire and usher in light and electricity. However, due to the need for two times of photosensitization, development, fixing, washing, etc., the process of this printing technology is complex. In addition, chemical cleaning can also cause serious environmental pollution

Bai Chunli made a vivid analogy: the laser Phototypesetting Technology of Chinese characters is equivalent to a film camera, which requires two steps (loading film and developing photos); Nano material plate making technology is equivalent to digital camera, which is more convenient to operate. This technology abandons the technical idea of photosensitive imaging, and can print pictures directly on the printing plate. There is a good cooperation between the working cylinder and the working piston, which reduces the number of image transfer, and there is no need to make up or repair the plate. The quality of printed pictures and texts is significantly improved, and there is no waste liquid discharge

Bai Chunli stressed that more importantly, China's independently developed nano material plate making technology enables domestic printing enterprises to complete the upgrading of printing technology at a lower cost. The Chinese Academy of Sciences plans to set up research and development and production centers for green printing plate making technology of nano materials in the South and north respectively. The North Center may be located in Beijing. There is no candidate city for the South Center, and Wuhan has the opportunity to fight for it

this technology allows China's printing industry to bid farewell to lead and fire and usher in light and electricity crbard (United States). However, due to the need for two times of photosensitization, development, fixing, washing, etc., the printing technology process is complex
