Flexographic printing, with its unique advantages such as low cost, strong adaptability, and environmental friendliness, occupies an important position in packaging printing, label printing, and other fields. However, in the pursuit of high-quality printing effects, flexographic printing also faces many challenges, one of which is the Moire Effect.

In today's era of increasing environmental awareness, various industries are actively seeking sustainable development paths, and the printing industry is no exception. As people's attention to environmental protection and health deepens, water-based ink, as an environmentally friendly printing material, is gradually becoming the new favorite of the printing industry, leading the future trend of green printing.

Water based ink, as an environmentally friendly printing material, is gradually being widely used in various fields, including the printing of plastic woven bags. Plastic woven bags, as a common packaging material, are widely used in various industries such as agriculture, chemical industry, and building materials. The printing quality of these bags directly affects the appearance and brand image of the products. Therefore, exploring the application of water-based ink in plastic woven bag printing is not only in line with environmental trends, but also an effective way to enhance product competitiveness.

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.
