Water-Based Ink

Water-based ink is primarily composed of water, pigments or dyes, resin binders, and a small amount of eco-friendly additives. It boasts excellent environmental properties, dries rapidly, which helps improve printing efficiency while maintaining vivid colors and clarity in printed materials. Additionally, it is easy to clean, causing minimal pollution to printing equipment and the environment.

UV Ink

UV ink is mainly composed of resin, pigment or dye, photoinitiator, and other specialized additives, and has excellent environmental friendliness. It can quickly cure under ultraviolet irradiation, significantly improving printing efficiency. UV ink has bright colors and high clarity. It is also easy to clean, thereby reducing pollution to printing equipment and the surrounding environment.
