Characteristics of UV Ink

Date: Oct 11 2024 From: Star Color

UV ink refers to ink that, under the irradiation of ultraviolet light, uses different wavelengths and energies of ultraviolet light to polymerize monomers in the ink binder into polymers, forming a film and drying the ink. The curing process of UV ink is a photochemical reaction process, and through instantaneous photochemical reactions, liquid UV ink can quickly transform into a solid state.

UV ink has good environmental characteristics. It abandons harmful solvents in traditional ink and uses ultraviolet curing technology to achieve an instant transition from liquid to solid state. This not only significantly reduces the emission of volatile organic compounds, but also ensures the health of the printing environment.

Characteristics of UV Ink

1. Free of volatile organic compounds: UV ink is almost completely free of organic solvents, so there will be no solvent erosion or damage to printed materials, nor will it pollute the human body and the environment. UV ink has significant advantages in environmental protection.

2. Good printing adaptability: UV ink does not change its physical properties during the printing process, has stable viscosity, and is not easy to paste or stack plates. UV ink has strong ink application power, high clarity, bright and bright ink color, strong adhesion, and is suitable for fine product printing.

3. Instant drying: UV ink can quickly cure under ultraviolet light irradiation, resulting in high production efficiency. This allows printed materials to be stacked immediately without sticking, greatly reducing the printing cycle.

4. Excellent physical and chemical properties: After UV ink is cured, it changes from a linear structure to a mesh structure, and has many excellent physical and chemical properties such as water resistance, alcohol resistance, wear resistance, and aging resistance. These properties make UV ink perform well in various applications.

5. Less ink usage: Due to the absence of solvent evaporation, UV ink has high effective components and can be converted into ink film almost 100%. Its usage is less than half of water-based ink or solvent based ink, greatly reducing the overall cost.

6. Strong color matching ability: By adjusting the viscosity, color tone, and brightness of the ink, rich colors can be matched. Simply mix two or more basic colors to obtain multiple desired colors.

7. Opacity is easy to control: By adding pigments or pigments to the ink, its brightness can be controlled to meet different printing needs.

8. Wide application range: UV ink is not only suitable for ordinary substrates such as paper, but can also be printed on non absorbent materials such as films, synthetic paper, metals, or plastics. This characteristic makes UV ink widely used in various fields such as packaging printing, advertising posters, and decoration.

9. Energy saving: The curing process of UV ink only requires the radiation energy used to excite the photoinitiator, which consumes less energy compared to traditional thermal curing methods.
The above is an introduction to the characteristics of UV ink, hoping to be helpful to you.

Zhongzhixing UV ink, as a pioneer in environmentally friendly printing, deeply practices the concept of green printing. By adopting advanced ultraviolet curing technology, harmful solvents in traditional inks are completely eliminated, achieving zero emissions from the source and setting a new benchmark for environmental protection in the printing industry. Zhongzhixing UV ink not only protects the health of printing workers, but also reduces the burden on the natural environment, making every printing a gentle care for the earth.
