Environmentally friendly ink, can you take the lead?

As the country's restrictions on the use and emission of VOCs become stricter, the National Environmental Protection Law was officially implemented on January 1, 2018, which has further promoted the rapid development of environmentally friendly inks

1.

Compared with ordinary inks, the main advantages of energy-curable inks are: it does not contain volatile organic compounds (VOCs) harmful to the human body and the environment, does not pollute the environment, fast drying and curing speed, low energy consumption, and high density of cross-linking and curing.

The environmental protection of UV ink is only relative to the ordinary printing process, and there are many problems: (1) Some components in UV ink contact the skin, which will produce a certain irritation, and even cause skin allergies

EB electron beam curing ink is a kind of ink variety with great development potential, currently only used for rotary offset printing and flexographic printing

2.

Traditional gravure printing inks contain a large amount of organic solvents (that is, VOCs).

The water-based process of gravure ink in the early stage is relatively slow, mainly due to the following reasons:

(1) Poor printing quality

(2) The dryness is not good

(3) The printing plate needs to be modified

Now with the emergence of high-performance water-based resins, not only has the problem of adhesion of water-based gravure inks to different film substrates been solved, but also the drying speed has been rapidly increased.

Three, environmentally friendly offset printing ink

Offset printing inks account for almost 50% of the market share in China.

(1) Vegetable oil-based offset printing ink

Soybean oil offset printing ink is the main variety of vegetable oil-based offset printing ink
.
At present, China's vegetable oil-based offset printing ink has made progress, and has formed a greater advantage in the adaptability of high-speed printing, product quality and sales price
.

(2) No aromatic hydrocarbon offset printing ink
.
In Japan, almost all ink manufacturers have begun to use AF solvents in which aromatic hydrocarbons have been removed from ink solvents to improve the environmental pollution of inks during production and printing
.
It should be said that this kind of offset printing ink made with AF solvent is also an environmentally friendly ink, but there is no AF solvent available in China, which also restricts the development of aromatic-free offset printing inks in China
.

(3) Waterless offset printing ink
.
Waterless offset printing uses an ink-repellent silicone resin-coated printing plate.
The ink can be absorbed by removing the coating on the image and text part to achieve the transfer of the image and text
.
This eliminates the need to use fountain solution and contributes to environmental protection
.
However, in the actual printing process, the waterless offset printing ink is greatly affected by the environmental temperature, and it is easy to get dirty.
The transferability of the ink and the ink property are not as good as ordinary offset printing inks, and special waterless offset printing equipment is required.
And promotion is subject to certain restrictions
.

In short, the environmental protection development of ink has been strongly promoted by policies, and the environmental protection upgrade and transformation of ink is imperative! Different product requirements, different printing methods, and different printing equipment need to choose corresponding environmentally friendly inks
.
Whoever can take the lead in the successful development and quickly promote the application will be able to seize the market opportunity, not only contribute to energy saving and emission reduction, but also get greater benefits!
