Why modern printing cannot do without ink defoamers?

With the popularization of high-speed printing and environment-friendly ink, foam has become an "invisible killer" that affects printing efficiency and product quality. Ink defoamers, through their unique chemical design, have become indispensable additives in the printing process.

1、 Eliminate defects and ensure printing accuracy

Foam can cause white spots, missed printing or uneven texture problems in printed matter. Defoamer can quickly eliminate bubbles by destroying the surface tension of foam to ensure that the ink is evenly transferred to the substrate. For example, in gravure printing, defoamers can reduce mesh bubbles and reproduce high-precision patterns clearly.   

2、 Improve production efficiency and reduce costs

Foam will force the printing machine to shut down frequently for cleaning, reducing production capacity. The addition of defoamer can reduce equipment maintenance time and avoid ink waste caused by foam. According to big data, the reasonable use of defoamers can reduce ink loss by 5% to 10%.   

3、 Compatible with environmental trends and meeting industry standards

With the promotion of water-based inks, traditional solvent based defoamers can no longer meet the demand. The new generation of organosilicon and polyether modified defoamers combines high efficiency and low VOC characteristics, and has passed the EU REACH certification, helping enterprises achieve green production.   

So modern printing cannot do without ink defoamers. From improving quality to reducing costs and increasing efficiency, the existence of ink defoamers is not only a technological choice, but also an inevitable result of industrial development.
