What is the name of screen printing ink?

1, Definition of screen printing ink
Screen printing ink, as the name suggests, is a type of ink specifically designed for screen printing processes. It is usually made by mixing and grinding pigments, resins, solvents, and additives. Through the mesh holes on the screen printing plate, the ink is transferred to the surface of the substrate under the pressure of the ink scraper, forming the required graphic and textual information. The performance of screen printing ink directly affects key indicators such as color, glossiness, wear resistance, and weather resistance of printed products. Therefore, choosing the appropriate ink is crucial to ensure printing quality.
2, Characteristics of screen printing ink
Wide adaptability: Screen printing ink can be applied to almost all types of substrate materials, including paper, plastic, metal, fabric, glass, ceramics, etc., demonstrating strong material adaptability.
Rich color expression: Screen printing ink can present bright colors and rich layers of printing effects, especially suitable for printing multi-color patterns and gradient effects.
Good adhesion and wear resistance: Screen printing ink can firmly adhere to the surface of the substrate during the printing process, forming a wear-resistant ink film to protect graphic and textual information from wear and tear.
There are various drying methods: There are various drying methods for screen printing ink, including volatile drying, UV curing, oxidation drying, etc. The appropriate drying method can be selected according to specific needs.
3, Classification of Screen Printing Ink
There are various classification methods for screen printing ink, which will be introduced from several main dimensions as follows:
Classification by substrate: Screen printing ink can be divided into paper ink, plastic ink, metal ink, glass and ceramic ink, etc. according to different substrates. Each ink is optimized for specific substrate characteristics to ensure optimal printing results.
Classified by drying method: Volatile drying ink is the most commonly used ink in screen printing, and its drying process is mainly achieved through the evaporation of solvents. UV curable ink utilizes UV irradiation to rapidly cure the ink and improve production efficiency. Oxidation drying ink dries by oxidizing the polymer in the ink in the air to form a polymer film.
Classified by Characteristics: Screen printing inks can also be classified based on their characteristics, such as fluorescent ink, glossy ink, magnetic ink, conductive ink, etc. These special inks play an irreplaceable role in specific application fields.
4, Application fields of screen printing ink
The wide application of screen printing ink makes it play an important role in multiple fields. In the packaging industry, screen printing ink is used to create exquisite packaging for high-end products; In the electronics industry, it is used for labeling products such as circuit boards and electronic components; In the textile industry, screen printing ink is used to produce printed fabrics with various patterns and text; In the advertising industry, screen printing ink also plays an important role, such as making large outdoor billboards, store signs, etc. In addition, screen printing ink is widely used in fields such as art reproduction and personalized gift making.
