Environmental performance of waterless printing
Waterless printing, suggests that it is not used in the printing process Pelton water (fountain solution), the environmental load. Anhydrous computer to plate (CTP version) generation, and more play out of the good characteristics of waterless printing, which was consistent with the sustainable development of the printing.
Waterless printing technology in the 1970s by the U.S. 3M Company first introduced, followed by Japan's Toray to buy the patent and commercial matters to be developed to achieve the industry in Japan and Europe continue to show its strong vitality and needs. In 1990, Dongguan Gold Cup Printing Co., Ltd. (hereinafter referred to as Gold Cup) successfully tested using waterless printing technology, but because of the price of the materials are too expensive, and ink roller temperature equipment and technology can not keep up, failed to waterless printing technology promotion to daily production. By 2006, the Gold Cup officially extensive use of waterless printing technology. Now, the Gold Cup at least 1 / 3 of the printing presses use water for production.
In recent years, environmental protection has become a hot topic, waterless printing technology more and more the concern of the industry. Through years of use, I summarize some of the advantages of waterless printing and weaknesses.
Environmental performance of waterless printing very
Traditional offset printing ink is dependent on the principle of mutually exclusive, so there are no images without ink hydrophilic areas, where there are no hydrophilic image with ink, but the water also causes a variety of print quality problems, such as excessive ink emulsification, water marks, etc., need to add alcohol (isopropyl alcohol) to reduce the side effects caused by the water. At the same time, isopropyl alcohol will produce volatile organic compounds (VOC), impact on the environment.
Version without watermark version is concave structure, the graphic part of the Ministry in depression, with ink; silicone coating on the plate with ink is not without the use of fountain solution. This way has several benefits.
First, because of water and isopropyl alcohol anhydrous version does not produce volatile organic compounds (VOC) emissions and waste water fountain, to protect the health of operators, to improve plant production environment, and environmental beneficial.
Second, the anhydrous version of the water way of developing red version, red version of the water treatment can be simple, non-hazardous substances, printed materials are environmentally friendly.
Third, the waterless printing using environmentally friendly plant-based oil-based waterless inks, safety and environmental protection.
Fourth, the traditional offset printing due to the role of water, dot gain rate is relatively large; waterless printing dot gain was smaller, so that printed graphics can be bright light, color rich layers, can effectively improve the quality.
Fifth, to solve the original waterless printing problems caused by water, effectively reducing makeready time, reduce the number of trial proofs printed, reducing the amount of defects, but also save the fountain solution and other materials. From this perspective, waterless printing will help reduce production costs.
