Ink Used For Screen Printing

Main ingredients

The core ingredients of screen printing ink include pigments, resins, solvents and additives. Pigments are responsible for providing rich colors and visual effects; resins are responsible for the adhesion and durability of inks, allowing patterns to be firmly attached to various materials; solvents are used to adjust the viscosity and fluidity of inks to ensure that the ink can pass through the screen smoothly and be evenly distributed on the target surface; additives are used to improve the fluidity, stability and drying speed of inks.

Application areas

Advertising and logo: Customized color and weather-resistant inks are used for outdoor billboards, logos, display boards, etc. to ensure color stability and durability in long-term use.

 

Packaging industry: Customized inks are used according to packaging materials and product types to meet food safety, chemical resistance and aesthetic requirements.

 

Electronic products: Provide specific functional inks for the housings and panels of electronic products, such as high temperature resistance and scratch resistance.

 

Textile printing: Customized wash-resistant and soft inks are used for printing textiles such as T-shirts and cloth.

Industrial applications: Customized inks are applied on mechanical parts, dashboards, industrial signs, etc. to ensure the durability and adaptability of inks.
