How to make ink products safer and healthier?

Through nearly 10 years of technological improvement, the ink-and-wash system has successfully resolved most of the previously existing difficulties, and it has changed its initial disadvantage as an advantage, and has gradually grown and matured. Under the premise of environmental protection, safety, and health, how the ink-and-wash products meet the requirements for optimal printing and post-processing, and the improvement of economic benefits is a topic that companies concerned consider.

1. Improve ink performance

The current performance requirements for ink users are: a stable pH ink system, the ink-manufacturing industry must develop inks with stable pH values ​​during the printing process, that is, there is no need to detect and adjust the pH during printing; re-dissolvability is another important factor. In the research field, the resin tends to solidify in the process of amine volatilization, and even fixes 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 be run longer before cleaning, ie, the production efficiency is increased; the ink application requires continuous improvement in the application performance of the polyethylene substrate. . The ink-manufacturing industry is expected to increase the surface resistance of ink-and-ink printing, especially in terms of oil resistance, grease resistance, and better heat and freezing resistance. Recently in Europe and North America, product innovation has been driven primarily by meeting user requirements. The specific requirements for ease of use come from users, which will also be the driving force for new product development.

2. Keeping up with the environmental situation

In order to achieve even more stringent environmental management goals, printers are always looking for new ways of solvent ink printing operations to meet government regulations. The current focus of the printing industry is to strengthen the handling of emissions from solvent ink printing. The usual practice is to use "incinerators" to absorb and incinerate VOCS. Other, more creative, applications are VOCS-based microbes or bacteria. All of these methods rely on the efficient absorption of VOCS for transport to systems that can be neutralized or incinerated or absorbed by microorganisms.
