In-depth analysis of ink knowledge, thoroughly understand the application of ink principle!

Ink is a commonly used printing material, which plays a role in the transmission of color and pattern in the printing process. Inks are usually composed of colors, adhesives, thinners and additives. Color is the most important component of ink, which determines the color and color of ink. The adhesive is used to adhere the color to the printing material, and the diluent is used to adjust the viscosity of the ink. Additives can improve the stability and durability of the ink.

The application principle of ink mainly involves the transfer of ink and the printing process. In the printing process, the ink is first transferred to the plate. The viscosity of the ink should be appropriate, too thin will affect the adhesion of the color, too thick is difficult to evenly transfer. The choice of adhesive and the use of additives can adjust the viscosity of the ink. After being transferred to the plate, the ink is surrounded by small dimpled parts of the plate, which are also called dots. In the printing process, the ink will only be attached to the dot, after the printing pressure, the ink is transferred to the printing material, the formation of patterns and text.

The printing process of ink mainly has several ways, including offset printing, gravure, letterpress and screen printing. Among them, offset printing is the most commonly used printing method, and it is also one of the most important application scenarios of ink. In the offset printing process, the ink is first transferred to the dented part of the plate, and then the ink is transferred to the printing material through the pressure of the roller. The roller in the offset printing process is usually made of rubber, which has a certain elasticity and can transfer the ink evenly to the printing material.

In the printing process, after the ink is transferred to the printing material, it also needs to go through a certain drying time, so that the ink can be cured quickly. The length of drying time depends on factors such as the nature of the adhesive in the ink and environmental conditions. Usually, the drying time of the ink needs to be between a few seconds and a few minutes.

The choice of ink is also an important factor. Different printing materials and printing methods require the use of different types of ink. For example, for more absorbent paper, you need to use a better absorbent ink, and for non-absorbent material surface, you need to use an ink that can be attached to it.

In practical applications, it is also necessary to consider the environmental protection and durability of the ink. On the one hand, the ink will release certain volatile organic compounds during the printing process, which will cause certain harm to the environment and human health. Therefore, the future ink should minimize its pollution to the environment. On the other hand, the durability of the ink is also an important consideration. Because the ink is exposed to the outdoor environment, it will be affected by ultraviolet light, acid and alkali, resulting in color fading and pattern blurring. Therefore, the weather resistance of the ink also needs to be fully considered.

In summary, in-depth analysis of ink knowledge can thoroughly understand the application of ink principles. The application principle of ink involves the transfer and printing process of ink, as well as the selection of ink and environmental factors. Ink research and innovation help to improve the quality and durability of printed matter, and promote the development of printing technology.
