Uv Invisible Ink Two Colors Under Different Wavelength Security Ink

UV Invisible ink, also known as security ink, is a substance used for writing, which is invisible either on application or soon thereafter, and which later on can be made visible by some means. Invisible ink is one form of steganography, and it has been used in espionage. Other uses include anti-forgey property marking, hand stamping for readmission, fun children's games, and marking for the purpose of identification in manufacturing.

UV Invisible Ink ,which can reflect 400-800nm visible light under theUV light,is a kind of Anti-forgery ink.According to the changes of the

color,this ink can be catalogued to invisible ink,color ink,color-change ink these 3 kind.Invisible ink is transparent color in common

environment.But under UV light,it can show out red,yellow,green,blue colors.The color ink can show its color more vivid and colorful.For

example,the color is red in common environment,it can become more red under UV light.

Basic Product Information

UV Invisible Ink — Two‑Color Response Under Different UV Wavelengths Security Ink UV invisible ink, also known as security ink, appears transparent in normal ambient light and reveals bright fluorescence under UV excitation. It belongs to steganography printing material, widely used for anti‑forgey, property marking, admission hand‑stamp, confidential marking and children creative games.

Under UV radiation (400‑800nm visible emission), this anti‑forgery ink can be classified into invisible transparent ink, color‑visible ink and photochromic ink. Our invisible ink stays transparent under natural light, and glows red, yellow, green or blue under UV lamp. Visible‑color ink shows enhanced vivid color under UV exposure.

Note: For non‑porous plastic films, increase hot‑air drying temperature or add slow‑dry solvent to prevent surface skinning.

3. Printing Method Compatibility Lookup Table

Tip: Mass‑production strongly suggests UV offset printing for stable dual‑wave fluorescent output.

4. Substrate Compatibility List

Warning: Dark‑colored substrates will reduce perceived UV fluorescence brightness.

5. Packaging Specification Selection Guide

Tips

1. Seal lid tightly right after opening to prevent solvent volatilization and ink skinning.
2. Do not mix with other ordinary offset inks.

6. Storage Conditions & Shelf‑Life Instruction

Storage Conditions

1. Store in cool, dry, dark ventilated warehouse, temperature 10‑25 ℃. Keep away from direct sunlight and UV‑light sources.
2. Keep far from fire, high‑temperature heat sources, oxidizing agents.
3. Container must be tightly sealed after opening; prevent solvent evaporation.
4. Separate storage from food, drinking water.

Shelf‑Life

• Unopened original package: 12 months from production date.
• After opening: Use‑up within 3 months; stir thoroughly before each printing run.

Warning: Expired ink may cause reduced fluorescence intensity, poor ink transfer and skinning defects.

7. Solvent‑Based Ink Safe Handling Guidelines & VOC Data

Safety Operation Guidelines

1. Ventilation: Workspace must equip effective exhaust ventilation system to remove solvent vapor.
2. PPE: Wear nitrile chemical‑resistant gloves, safety goggles, protective apron. Avoid direct skin & eye contact. In case of contact, rinse with plenty of clean water immediately.
3. Fire prevention: Solvent‑based ink is flammable. No open flame, no spark sources nearby. Equip fire extinguisher in press room.
4. Waste disposal: Waste ink, contaminated rags must be collected as hazardous chemical waste, follow local environmental regulation.
5. Do not inhale solvent vapors for long‑time period.

VOC Emission Data

• VOC Value: 345 g/L (tested according to ISO 11890‑2).

Remarks: This is solvent‑based security ink, not zero‑VOC UV‑curing ink. Please check local environmental regulation before usage. MSDS document available upon request.

8. Complete Anti‑forgey Detection Instruction (Naked‑Eye / UV / IR / Magnetic)

Core security highlight: Dual‑wavelength two‑color effect. Different glowing colors under long‑wave vs short‑wave UV lamp, higher anti‑forgey level than single‑wave UV ink. Suggestion: Combine with magnetic ink / water‑sensitive ink to build multi‑layer anti‑forgey solution for high‑security documents.

9. Application Scenarios & Case Display

1. Ticket & Voucher Anti‑forgey Hidden covert marks printed on lottery tickets, admission tickets, gift vouchers. Authenticators verify via dual‑wavelength UV lamp.
2. Certificate & Official Document Anti‑forgey Qualification certificates, membership cards, confidential documents. Invisible UV security mark only detectable under professional UV inspection lamp.
3. Packaging & Brand Label Anti‑forgey High‑value goods packaging, luxury product labels. Hidden logo or serial pattern for brand anti‑forgey, invisible to naked eyes.
4. Confidential Marking & Steganography Printing Secret marking for internal confidential documents, property asset marking.
5. Creative Special Printing Hand‑stamp, children interactive creative printing projects.

11. FAQ (Frequently Asked Questions)

Q1: What is minimum order quantity? A: MOQ is 1 KG. 500 g trial can is available for lab testing. Bulk‑order enjoys better unit price.

Q2: What is production lead‑time? A: Stock standard color‑match formula: within 3 working days after payment. Custom dual‑wavelength color combinations: 7‑10 working days.

Q3: Can you provide customization service? A: Yes. We can adjust fluorescence brightness, tune viscosity for specific offset press, develop new long‑wave / short‑wave color combinations. Send your printing requirement for technical evaluation.

Q4: What shipping methods are available? A: Classified as chemical goods. International shipping via DHL/FedEx special chemical channel or sea freight. Domestic delivery by land transport. Freight depends on weight and destination country. MSDS will be supplied for shipping document.

Q5: Why fluorescence is dim / weak after printing? A: Common causes: ①Ink film too thin; ②Excessive fountain‑solution emulsification on offset press; ③Substrate is dark‑colored; ④Ink expired. Run pre‑sample test before mass‑production.

Q6: Can I mix this ink with regular CMYK offset ink? A: Not recommended. Mixing will reduce or destroy dual‑wavelength fluorescent performance. Print as separate independent ink unit.

Q7: How to clean offset press after use? A: Use offset solvent wash thoroughly for ink roller, blanket and plate. Residual invisible ink contaminant may cause unexpected glowing defect for next printing jobs.

12. Comparison Table with Similar Products (Highlight Our Advantages)

Highlight: Most competitive UV invisible ink only supports single‑wavelength single‑color glowing. CERES YT series delivers dual‑wavelength two‑color feature, which greatly raises foegey difficulty, ideal for high‑level security printing projects.
