Night luminous ink is widely used in security printing, artistic designs, and product labeling. But how does it work? The glowing effect results from specialized chemical compounds that absorb and emit light.
In this article, we will explore the core luminous principles behind night luminous ink, including luminescence storage, self-luminescence, and fluorescence contrast. By understanding these processes, you can make informed decisions when choosing high-quality, luminous ink for your projects.
1. Luminescence Storage: How Ink Absorbs and Releases Light
One of the most common principles of glowing security ink is luminescence storage. This process involves phosphorescent materials that absorb light energy and release it over time.
1.1 How It Works:
When exposed to light, the ink stores energy from UV rays or other light sources.
After the light source is removed, the stored energy is gradually released as a soft glow.
The duration and intensity of the glow depend on the quality of the phosphorescent materials.
1.2 Advantages:
Long-lasting glow after exposure to light
No need for continuous external energy
Ideal for safety signs, watches, and security features
1.3 Best Applications for Luminescence Storage Ink:
Security printing: Prevents counterfeiting by adding hidden night-luminous ink markings.
Emergency exit signs: Glow in the dark for visibility.
Decorative designs: Used in art, packaging, and novelty products.
2. Self-Luminescence: The Power of Chemiluminescence
Unlike stored light emission, self-luminescence generates light through chemical reactions. This process, known as chemiluminescence, produces a continuous glow without needing external light.
2.1 How It Works:
Chemical compounds in the custom night luminous ink react and produce light.
The reaction sustains the glow without requiring prior light exposure.
The brightness depends on the chemical composition and reaction rate.
2.2 Advantages:
Does not need external light charging
Can be used in extreme conditions
Highly stable glow effect
2.3 Best Applications for Self-Luminescent Ink:
Military and emergency equipment: Ensures visibility in dark environments.
Industrial safety markings: Maintains visibility in low-light conditions.
Anti-counterfeiting applications: provide a unique authentication feature.
3. Fluorescence Contrast: The Secret Behind UV-Activated Glowing Ink
Some security night luminous inks work by fluorescence contrast, where the ink is invisible under normal light but glows under UV (ultraviolet) light. This makes it a key material for high-security applications.
3.1 How It Works:
The ink absorbs UV light and emits visible fluorescence.
The glow disappears immediately when UV light is removed.
The brightness and color depend on the fluorescent pigments used.
3.2 Advantages:
Only visible under UV light for added security
Available in multiple glowing colors
Long-lasting and fade-resistant
3.3 Best Applications for Fluorescent Night Luminous Ink:
Banknotes and legal documents: Prevents counterfeiting with hidden markings.
Brand protection: Ensures product authenticity.
Concert and event tickets: Provides security verification.
