Industry: the future development of water - based ink
When the printer performs stringent environmental objectives, the chain reaction is generated throughout the entire supply chain of the printing industry. In order to eliminate the VOCS released by the solvent-based system, that is, to meet EPA's requirements to reduce or eliminate VOCS, printers are looking for new technologies. For ink formulation designers, one possibility is to develop water-based systems that can reduce VOCS. Now that the ink has been improved, it has had a significant impact on many areas of the printing industry, especially for flexographic printing. It is foreseeable that ink will continue to grow. The future of ink development depends on the guidance of the EPA; it depends on whether the printer's existing incineration, absorption and handling of the equipment after the depreciation of water-based printing; depends on the ink manufacturers to further improve the performance of ink in order to gain more market share. Specifically, the future development trend of ink is:
First, to further improve the performance of water-based ink makes it easier to use
The improvement of ink technology has been gradually accepted by the flexographic printing market, mainly due to years of ink has been catching up with solvent ink system and easy to use and simple printing has an advantage. Now when the flexographic printing industry compares and selects ink or solvent ink, confidence in ink has risen so that more printing work has been done by water-based flexographic printing. Recently in Europe and North America, product innovation is mainly to meet user requirements as a driving force. Easy to use the specific requirements from the user, which will also be the driving force of new product development. At present, the improved performance of ink users is: PH stable ink system, ink manufacturing industry must develop in the printing process PH value of stable ink, that is, no need to detect and adjust the PH value in the printing; re-solubility is another important In the field of research, when the amine volatilizes the resin tends to cure, even on the plate. Recently, ink manufacturers have improved the performance of the resin to make it easier to dissolve, which means that the printing system can run longer before cleaning, that is, increased production; ink applications require continuous improvement in the application of polyethylene substrates Performance; ink-based printing packaging for alkali resistance, as well as in frozen food packaging applications. The ink-making industry is expected to improve the surface resistance of ink-borne prints to make more products water-based, especially in oil resistance, grease resistance and better heat resistance and resistance to freezing.
Second, environmental protection will be the key to future profitability of water-based ink.
Ink in the future market is able to enter another climax, ink manufacturing industry as the government's initiative as the ultimate driving force. EPA has been calling for the final zero emissions of VOCS, which means that the need to gradually reduce VOCS emissions will eventually promote the application of ink. At this stage there is pressure from all aspects of the environmental problems that will be further concerned. In order to achieve stricter environmental management objectives, printers are always looking for new methods of solvent ink printing operations to meet government regulations. The current focus of the printing industry is to strengthen the handling of emissions during solvent ink printing. The usual practice is to use "incinerators" to absorb and incinerate VOCS, and the other is more creative to use VOCS-based microbiological or bacterial treatment systems The All of these methods rely on efficient absorption of VOCs to the system that can be neutralized, either incinerated or absorbed by microorganisms.
Although the environmental protection department has not yet fully detailed development plan, but continue to strengthen the guidance and management, but we believe that a strong environmental protection will be the ultimate shift to the significance of ink.
In short, with the concerted efforts of the relevant industry, the ink supplier provides better ink and ink, the film is easier to supply the surface of the water, the manufacturer of the press manufactures better drying equipment for the water-based system. Continued growth and provides a very viable way for printers to follow the low VOCS process.
