Introduction to Ink Types for Digital Printing Equipment

Four commonly used ink types: Water-based ink, UV ink, Solvent ink, and Eco-solvent ink. Detailed explanations are as follows:

01 Water-based Ink

Core Features

  1. Eco-friendly and Safe: Formulated with water as the solvent, odor-free, and free of pungent chemical fumes.
  2. Process Requirements: Soluble in water. Lamination protection is mandatory after printing.
  3. Color Performance: Delivers delicate and high-saturation colors, ideal for photo printing and art reproduction.
  4. Printer-friendly: Non-corrosive to printheads, effectively extending the service life of printing equipment.

Application Scenarios

Exclusively for indoor advertising, including indoor photo printing, decorative paintings, art reproductions, and indoor posters.

02 UV Ink (Core Factory Ink)

Curing Principle

UV ink is liquid when ejected from the printhead and cures instantly into a solid state under UV ultraviolet irradiation with no drying waiting time required.

Universal Printing Materials

Compatible with almost all printing substrates, including flexible films, banner fabrics, leather, plastic, metal, glass, wood, acrylic, ceramic tiles and other coiled and rigid board materials.

Three Classifications of UV Ink (Material-based Selection)

  • Soft UV Ink: Flexible and stretchable, suitable for deformable flexible materials.
  • Neutral UV Ink: Balanced soft and hard properties for universal application.
  • Hard UV Ink: Specially designed for rigid materials such as metal, glass and ceramic tiles.

Advantages

Features extremely strong adhesion, preventing ink smudging after printing. Suitable for both indoor and outdoor applications.

03 Solvent Ink

Pros and Cons

  • Advantages: Excellent outdoor weather resistance, waterproof and wear-resistant, low procurement cost.
  • Disadvantages: Strong pungent chemical odor, poor environmental performance.

Application Scenarios

Ideal for low-cost large-scale outdoor advertisements, most commonly used for banner printing.

04 Eco-solvent Ink

Core Advantages

Balances environmental friendliness and outdoor durability, featuring waterproof, sun-resistant and high-precision printing performance.

Typical Applications

Used for high-precision outdoor printing, mainly including vehicle body stickers and high-end outdoor photo stickers.
