Starcolor-ink

UV (ultraviolet light curing) ink is a type of ink that polymerizes monomers into polymers through different wavelengths and energies of ultraviolet light under ultraviolet irradiation, thereby achieving ink film formation and drying. It has been widely used in the printing field due to its advantages such as fast drying speed, good gloss, bright colors, water resistance, solvent resistance, and good wear resistance. However, the curing time of UV ink under fluorescent lamps is a relatively complex issue that requires further exploration.

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: 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.
