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.

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.

The difference between gravure printing and flexographic printing. These two printing methods differ in terms of principles, application areas, and printing effects.

Gravure Printing

principle

Plate making process: The plate for gravure printing is usually made of metal (such as copper or steel), and fine grooves are formed on the surface of the plate through chemical etching or laser engraving, which form the printing pattern.

The development process of gravure printing can be traced back several centuries, and its technology continues to evolve, becoming an indispensable part of the modern printing industry. The following is the main development process of gravure printing:

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.
