There is no need for sensitive flushing, waste water is not produced, newspapers and books can be printed, and the circuit boards of computers and mobile phones can be easily printed out without etching. These seemingly amazing technologies in our country The efforts of the scientific research team have become a reality. This is the leading nano green printing technology in the world of printing. With the advantages of high resolution, energy saving, environmental protection and low cost, it has revolutionized the printing industry and printed circuit board industry.
Nano Green Printing Technology Leaves Traditional Laser Photographic Plate Making Out of Stage
Traditional laser photolithography requires the same exposure as the camera film, and the use of chemicals such as developer and fixer can cause a lot of contamination. Even the most advanced computer-to-plate technology currently requires photographic precoating and chemical processing. The nano green printing technology does not require a darkroom and exposure process at all, does not generate waste water and waste liquid, and costs 1/3 more than a conventional laser photofinishing plate.
Live Nano Green Printing Technology
At the nano-green printing industrialization base of the Institute of Chemistry of the Chinese Academy of Sciences in Huairou, Beijing, the reporter experienced the magic of the nano-green printing technology. I saw a few seemingly inconspicuous platesetters on the production floor. The staff was putting an aluminum plate into one of the machines. In less than three minutes, one plate came out from the end of the machine. There is no pungent chemical smell, no plumbing, no loud noise, and the entire plate making process is completed with ease.
How Nano Green Printing Technology Works
The principle of nano-green printing plate making technology is to print out the oleophilic graphic area formed by nano-materials on the hydrophilic plate, and to form the difference between the graphic area and the blank area through the difference of lipophilicity and hydrophilicity. The plate of the plate is hydrophilic in nature, which makes it free from oily inks, while the graphic area on the print is printed with oleophilic nanomaterials. In this way, when the printing plate is inked on the printing machine, the area printed with the oleophilic nano-material obtains the picture and the text, and the area without printing the oleophilic nano-material is still blank.
Our Opportunity: Non-Photosensitive New Technologies
Avoiding the light-sensing and rinsing process, the process of directly printing the pattern through the control of the hydrophilic and oleophilic properties of the nano-materials does not sound complicated. However, more than 10 years ago, when Song Yanlin first proposed this idea, he was greatly questioned by the industry: “If this method is feasible, why did foreign researchers and large companies delay?” Digital photographic technology was the earliest Kodak. The company developed, but due to its conflict with its core photographic materials industry, Kodak’s indecision ultimately led them not to lead the industry in digital photography. The same is true in the printing industry. International giants such as Kodak, Fujifilm, and Agfa have started with photosensitive materials. It is very difficult to choose between new and non-photosensitive technologies. "This is our opportunity."
