5. What are the printing methods of ink?

Ink can be applied to a variety of printing methods, common including offset printing, letterpress, gravure, screen printing and so on. Different printing methods require different inks to have different properties, such as fluidity, viscosity and fast drying.

6. How is the color of the ink obtained?

The color of the ink is determined by the pigment. Pigments can be natural, such as plant extracts, ores, etc. It can also be synthetic, such as organic dyes and pigments. Through different pigment combinations and concentrations, a variety of different colors can be obtained.

7. How long is the drying time of the ink?

The drying time of the ink depends on a number of factors, including the composition of the ink, the nature of the printing material, and environmental conditions. In general, the ink will dry between a few seconds and a few minutes.

8. What are the special requirements of ink use?

Ink needs to pay attention to some special requirements when using. For example, the ink should be protected from bright direct sunlight during storage, so as not to fade the pigment; When in use, the printing area should be kept clean to avoid dust and impurities.

9. What is the environmental impact of ink?

The manufacture and use of ink may have a certain impact on the environment. For example, solvents contain volatile organic compounds (VOCs), which can pollute the air; The metal elements in some inks may have a negative effect on water and organisms. Therefore, the development and use of ink needs to comply with environmental regulations and standards.

10. How to treat and store waste ink?

Waste ink should be handled by a special agency to avoid pollution to the environment. Disposal methods usually include recycling, reuse or combustion. Waste ink should be stored in containers marked with warning labels to prevent leakage and misuse.
