During the operation of water-based ink printing plants, wastewater containing water-based ink is generated, which needs to be treated appropriately to meet discharge standards. The following are sewage treatment equipment that water-based ink printing factories may need to equip:

Printing plants using water-based ink do indeed require wastewater treatment. This is because water-based ink wastewater has some special properties, such as high COD (chemical oxygen demand), high chromaticity, and difficult biodegradation. If directly discharged into the environment, it will cause serious pollution to water bodies, threatening human production and life as well as the ecological balance of nature.

There are various dilution methods for water-based ink, and the specific method used depends on the required dilution effect, printing requirements, and the characteristics of the ink itself. Here are some common dilution methods:

The control of pH value is crucial during water-based ink printing. The pH value not only directly affects the printing performance and print quality of ink, but is also closely related to multiple technical indicators such as ink viscosity and drying speed. The following is a detailed explanation of pH control during water-based ink printing:

Water based ink is widely used in the printing field due to its environmental and safety characteristics, and non-woven fabrics have become an ideal choice for many products due to their softness, breathability, and environmental friendliness. However, as a non absorbent material, non-woven fabric may also experience color fading when printed with water-based ink. Let's take a look at the reasons for this.

Water based ink, as an environmentally friendly, non-toxic, and easily degradable printing material, is gradually occupying an important position in the printing industry. Non woven fabric, with its unique physical properties and wide range of applications, has also become an important material in modern packaging, home furnishings, medical and other industries. So, can water-based ink be used for printing non-woven fabrics? The answer is affirmative.

There are significant differences in the performance between oil-based ink and water-based ink. Here is a comparison of their main properties:

As a crucial component of food packaging materials, food-grade inks must not only meet aesthetic printing requirements but also ensure food safety and environmental performance.

In the field of water-based ink printing, ink cracking is a frequently encountered issue that significantly impacts the overall quality and aesthetic appeal of printed products. Cracking not only compromises the smoothness and glossiness of prints but also potentially reduces their abrasion resistance and water resistance, affecting product longevity and market competitiveness. 

Amid the growing emphasis on environmental protection, water-based inks have garnered significant attention and application in the printing industry due to their low toxicity, odorlessness, and eco-friendly properties. However, during actual production processes, printers often encounter issues with poor drying of water-based inks.
