"Environmental protection ink, green printing" has become the theme of the development of

the ink printing industry in the 21st century. In recent years, many countries and regions have

increased the requirements and constraints of hygiene and environmental protection in

packaging and printing, especially for medicines, food, and children's products. It is clearly

pointed out that the use of printing materials with toxic and harmful ingredients is strictly

prohibited. Green ink is a passport to enter the international market and the direction of

future development.

1. Offset lithographic inks, among various printing methods, offset lithographic inks account

for nearly 50% of the total in my country, and still occupy a dominant position, and will continue

to develop steadily in the next 20 years. There are two main printing methods: lithographic

sheet-fed printing and lithographic web printing. Their varieties, specifications and quality

have reached a very high level, but most of the inks used are non-environmental friendly.

At present, foreign countries must use environmentally friendly inks in food and pharmaceutical

packaging and printing, such as non-aromatic and solvent-free lithographic offset printing inks.

2. Water-based ink, water-based ink is an environmentally friendly printing ink recognized

by the world's printing industry. It has the most development prospects and is also the best

target for our efforts to develop and promote. In recent years, it has developed extremely fast,

especially in the international market, it is being widely used. The biggest difference between

water-based ink and solvent-based ink is that the solvent used is water instead of organic

solvent, which does not affect human health, does not pollute the environment, and is not

easy to burn. It is especially suitable for printing food, medicine, children's toys and

other packaging.

3. UV ink, uv ink is a kind of ink that uses different wavelengths of ultraviolet energy to dry

the ink film quickly under the irradiation of ultraviolet rays. uv ink is 100% material

film-forming, no solvent volatilization, and the ink film has excellent abrasion resistance

and chemical resistance. Although it has been developed in China, there were only uv

printing paper and iron printing ink at first, with few varieties, high prices, and low output,

which could not meet the needs of domestic printing factories. Great progress

has been made in recent years.

4. Digital printing ink, nowadays, digital printing has become a new development trend

in the field of packaging and advertising printing at home and abroad, and a considerable

number of digital printing machines have been imported in China. In order to make the

digital printing machine not only adapt to the requirements of high-speed printing,

but also achieve good printing quality, digital printing ink is very important.
