Ink is a common printing material, widely used in publishing, printing, advertising and other fields. However, the organic solvents and heavy metals used in the traditional ink preparation process have a certain impact on the environment and human health. In order to reduce the impact of ink on the environment, researchers have proposed a variety of environmentally friendly ink preparation methods. In this article, we will explore which ink is the most environmentally friendly and analyze the relationship between ink knowledge and environmental protection.


First of all, environmentally friendly ink is a kind of ink that is harmless to the environment and human health. At present, the researchers have improved the composition, preparation process and application of the ink. The composition of environmentally friendly ink often does not contain harmful substances such as organic solvents and heavy metals. Instead, they use water-based solvents and inorganic pigments, which are safe for the environment and humans. In addition, the preparation process of environmentally friendly ink also reduces the discharge of waste water, waste gas and waste solids as much as possible to reduce environmental pollution.


From the type of ink, water-based ink is considered to be the most environmentally friendly one. Water-based inks use water-based solvents as the main solvent, rather than organic solvents. In contrast, organic solvents release harmful substances such as volatile organic compounds (VOCs) when they dry, polluting the atmospheric environment. Water-based solvents do not produce similar problems, so the use of water-based ink can effectively reduce the negative impact on air quality.


Another environmentally friendly ink is UV ink. UV ink is a kind of ink that contains a photosensitive substance, which needs to be irradiated by ultraviolet light to cure. Compared with traditional inks, there is almost no emission of volatile organic compounds in the preparation process of UV ink, which reduces the pollution of the atmospheric environment. In addition, UV ink also has the advantages of fast drying speed and good printing effect, which is gradually favored by the printing industry.


In addition to the composition and type of ink, the preparation process of ink also plays an important role in environmental protection. The traditional ink preparation process usually requires the use of a large number of solvents and auxiliary agents, resulting in a large amount of waste water and exhaust gas. The preparation process of environmentally friendly inks is often more environmentally friendly, such as the use of new technologies such as solvent-free and low-temperature preparation. These processes reduce the discharge of waste water and waste gas, but also improve the quality of ink and printing effect.


In general, water-based inks and UV inks are considered to be the most environmentally friendly ink types. They do not contain harmful substances such as organic solvents and heavy metals, and reduce environmental pollution during the preparation process. In addition, the ink preparation process also plays an important role in environmental protection, the new preparation process can reduce waste water, exhaust gas emissions, improve the quality of ink and printing effect.


However, it is important to note that each ink has its own advantages and disadvantages and scope of application. When selecting the type of ink, it is necessary to consider the requirements of printed matter, process conditions and environmental protection factors. Only in practice, continuous exploration and improvement, in order to better achieve the balance of environmental protection of ink and print quality.
