Future development trends of water-based inks

1. Further improve the performance of water-based inks to make them easier to use

water ink technology is gradually accepted by the flexographic printing market in the process of improvement, mainly because water ink has been catching up with solvent ink system for many years and has advantages in ease of use and simple printing. Nowadays, when the flexographic printing industry is comparing and choosing water ink or solvent ink; Confidence in ink and wash has been the company's introduction of European, American and Japanese testing instruments, and the rise in production technology has made more printing work completed by water-based flexographic printing. Recently, in Europe and North America, product innovation is mainly driven by meeting user requirements. The specific requirements for ease of use come from users, which will also be the driving force of new product development. At present, the performance that ink users require to improve lies in: the ink system with stable pH value, and the ink manufacturing industry must develop ink with stable pH value in the printing process, that is, there is no need to detect and adjust pH value in the printing process; Re solubility is another important research field. When amine volatilizes, the resin tends to solidify, even on the printing plate. Recently, ink manufacturers have improved the performance of the resin to make it more soluble, which means that the printing system can run for a longer time before cleaning, that is, to increase the production capacity; The application of water ink requires continuous improvement in the application performance of polyethylene substrate; Alkali resistance of ink printing packaging and its application in frozen food packaging. The ink manufacturing industry is expected to improve the surface resistance of ink prints and make more products water-based, especially in oil and grease resistance, as well as better heat and freezing resistance

2. Environmental protection will also be the key to the future profitability of water-based inks.

whether ink can enter another climax in the future market, the ink manufacturing industry regards the government's measures as the ultimate driving force. EPA has always required the final zero emission of VOCs, and additional experiments for printers mean that the emission of VOCs must be gradually reduced, which will eventually promote the application of ink. At this stage, there is pressure from all sides, indicating that environmental issues will be further concerned. In order to achieve more stringent environmental management goals, printers are always looking for new methods of solvent ink printing operation process to meet government regulations. At present, the printing industry focuses on strengthening the treatment of emissions in the process of solvent ink printing. The usual practice is to use an "incinerator" to absorb and incinerate VOCs. Other more creative is to apply the treatment system of microorganisms or bacteria that feed on VOCs. All these methods rely on efficient absorption and transmission of VOCs to systems that can neutralize it, either by incineration or by microorganisms

although the environmental protection department has not yet made a detailed development plan, but continues to strengthen guidance and management, we believe that the strong guidance of environmental protection will be of great significance to the final shift to ink painting

in a word, with the joint efforts and cooperation of relevant industries, that is, ink suppliers provide better ink, film supply a surface layer that is easier to water, and printing machine manufacturers manufacture better drying equipment for water-based systems. The use of ink will continue to grow and provide a very feasible way for printers to raise the total amount of waterproof works to 2billion yuan in the process of moving the condenser down and aligning the glass specimen to reduce VOCs
