Kunming, August 31, Xinhua (reporter Zhang Dongqiang) "tap water offset printing system" innovation technology press conference was held in Kunming, Yunnan Province on August 29. The "zero alcohol offset printing system" introduced by the press conference is commonly known as "tap water offset printing system", which is an innovative technology of replacing "wetting original solution" with "tap water". The application and promotion of this technology will help to realize the green development of printing industry.

The reporter learned at the press conference that the "tap water offset printing system" uses the "principle of water ink balance" in offset printing to improve the hydrophilicity of water rollers in the waterway system, and uses physical wetting method to replace the chemical wetting method. Alcohol, isopropanol or other alcohol and ether substitutes are not used in the fountain solution, and the film-forming ability of fountain water is greatly improved, Can be in the fountain water completely without alcohol or isopropanol, can still be wetting liquid evenly spread thin film.

According to the introduction of this version, it can eliminate the hazards of alcohol waste gas, such as environmental protection, environmental protection, and elimination of alcohol pollution.

On August 5, China Science and Technology Co creation (Beijing) science and Technology Achievements Evaluation Center organized an expert group in Kunming to evaluate the scientific and technological achievements of the project. The expert group said that in view of the problems of chemical pollution and volatile organic compounds emission in the traditional fountain solution used in the production process of newspaper rotary press in printing industry, the research and development of "newspaper rotary machine water offset printing system" has obtained domestic and foreign invention patents, with independent intellectual property rights, and has solved the pollution problem of traditional fountain solution from the source, and the technology innovation and application The effect is remarkable.

The technology, led by Zhou Daoming, general manager of Yunnan zhuoyin Technology Co., Ltd., was successfully developed in 2015 after 20 years of industry practice and 10 years of technology exploration and development. The technology has been authorized by Chinese invention patent, American and European Union invention patent.
