In people's impression, gravure printing uses solvent based ink, which not only pollutes a lot but also does not comply with environmental regulations. Therefore, many printing factories have switched from gravure printing to flexographic printing. Of course, some printing factories have also changed from solvent based ink to water-based ink for use. So, can water-based ink be used in gravure printing?

The environmental challenges of gravure printing are mainly reflected in the following aspects:

1、 Volatile Organic Compounds (VOCs) emissions

Large emissions: Solvent based inks and cleaning agents used in gravure printing processes release large amounts of VOCs, which can easily form photochemical smog in the atmosphere, posing a threat to the environment and human health.

There are significant differences between UV tattoo ink and UV printing ink in multiple aspects. The following is a comparison of the two from different perspectives:

1、 Composition and Characteristics

UV tattoo ink:

Ingredients: UV tattoo ink usually contains photosensitive polymers, pigments, additives, etc., which can quickly cure under UV light irradiation.

Chapter 1: The Dawn Sprouting from Difficulties

In early 20th century New York, Allen Smith was a young engineer passionate about printing technology. He witnessed the various limitations of the printing industry at that time, especially the threat to workers' health posed by the toxic ink used in aniline printing, which deeply touched him. So he began to study day and night in his own rudimentary laboratory how to improve this technology.

Chapter 1: Dawn in the Laboratory

In the late autumn of 1959, in a small chemical research institute in Manchester, England, Dr. Alan Harvey was standing in front of his experimental table, holding a special dropper in his hand, slowly dropping a drop of transparent liquid into a glass container with an ultraviolet lamp. This droplet of liquid is the closest to the successful UV ink formula he has tried countless times.

The light source of UV ink plays a crucial role in the curing process of UV ink, and their selection directly affects the curing speed, curing quality, and production cost of the ink. The following is a comparative analysis of UV ink light sources:

Photoinitiators play a crucial role in UV ink by triggering photochemical reactions in the ink, thereby achieving rapid curing of the ink. The following is a detailed discussion on the role of photoinitiators in UV ink:

There are various additives required for UV ink printing, which play a crucial role in the manufacturing, use, transportation, and storage of ink. The following are some commonly used additives and their main functions in UV ink printing:

UV ink is widely used in various fields such as packaging, labeling, advertising, etc. due to its excellent curing speed, vivid color, and wear resistance. However, the issue of bubbles generated by UV ink during the printing process is a significant challenge that cannot be ignored. It not only affects the appearance quality of printed materials, but also poses a threat to the stability and efficiency of the entire production process.

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.
