[China Packaging Network News] Recently, Jilin Science and Technology Week 2015 and "Jilin University Students' Environmental Innovation Technology Achievement Exhibition" was launched at Jilin University. The "inkless printing technology" developed by the College of Chemistry of Jilin University has become the focus of the day. According to experts' estimation, after the application and promotion of this scientific research result, it can save China's printing and printing consumables an annual cost of up to 300 billion yuan. This printing technology cost is only 1% of inkjet printing technology.
"The principle of inkless printing technology is based on dyes that change in color with water, and can be reused as a printing paper. In combination with the existing ink jet printing technology, water can be printed on behalf of the ink."
According to Sheng Lan, a student at the College of Chemistry at Jilin University, this type of inkless printing technology can produce different colors of water spray prints according to different water color change dyes. In response to traditional paper-based methods such as low paper utilization rate, severe waste of resources, and high follow-up costs and cartridge jams caused by frequent replacement of ink cartridges, the school’s teacher Zhang Xiaoan brought his own research team and developed this type of design through years of experiments. New waterless ink printing technology. This technology can be used to prepare different types of water-based writing paper. The water-sprayed writing can also be stored for different times up to 100 hours. Each water-based writing paper can be reused more than 15 times. This related technology has declared 3 inventions. Patents, including "new reusable water writing paper technology" have been granted a patent.
"The ink-free printing technology is compatible with existing inkjet printers. Users only need to purchase matching water writing paper and water cartridges to enjoy the experience brought by this new technology." But Shenglan also said that this inkless Printing technology cannot replace ink jet printing technology completely for the time being, because it has not broken through for a longer period of time. This technology is suitable for one-time reading documents printing, such as government or company confidential meetings, home personalized news newspapers and periodicals printing, etc. It has a very good market prospect. Some authoritative agencies make estimates for their technologies: In-depth development and gradual promotion can save China's printing and printing supplies costs as much as 300 billion yuan each year.
