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.

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.
Seven Available Wavelength‑Color Matches:
| Long‑wave | Blue | Red | Yellow | Blue | Red | Yellow | Blue |

2. Ink Viscosity / Tack / Flow / Drying Performance Table (Test
Condition: 25 ℃, 55% RH)
| Test Item | Specification | Remarks |
|---|
| Viscosity | 60‑80 Pa·s | Sheet‑fed offset press standard; adjust with offset solvent reducer |
| Tack | 9‑12 | Suitable for sheet‑fed offset; avoid excessive emulsification |
| Flow | 27‑33 mm | Good ink transfer, no grainy dot |
| Surface Dry | 8‑14 min | On paper substrate |
| Through Dry | 60‑90 min | Plastic substrate will extend full‑dry time |
| Ink Fineness | ≤9 μm | Fine pigment particle, no plate abrasion |
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
| Printing Method | Compatibility | Notes |
|---|
| Offset Printing (UV Offset) | ✅ Highly Recommended | Formulated specially for offset security printing, best dot
reproduction |
| Letterpress | ⚠️ Conditional test only | Re‑tune viscosity & tack; custom trial required, not stock formula |
| Gravure Printing | ❌ Not suitable | Rheology mismatch; cannot maintain dual‑wavelength fluorescent
performance |
| Screen Printing | ⚠️ Conditional usable | Must add special screen‑printing thinner, contact technical support |
Tip: Mass‑production strongly suggests UV offset printing for
stable dual‑wave fluorescent output.
4. Substrate Compatibility List
| Substrate | Compatibility | Operation Tips |
|---|
| Coated / Art Paper | ✅ Excellent | Best fluorescence brightness; ideal for certificate & voucher
anti‑forgey |
| Uncoated Paper / Cardboard | ✅ Good | Avoid super‑absorbent paper which weakens fluorescence intensity |
| Synthetic Paper | ✅ Good | Keep substrate clean, free of oil contamination |
| PVC / PET Plastic Film | ✅ Usable | Surface tension ≥38 dyn/cm; corona‑treatment for PP/PE films |
| Metal foil / Metallized paper | ⚠️ Conditional usable | Pre‑test adhesion & fluorescence; metal reflection may affect
visual glowing effect |
Warning: Dark‑colored substrates will reduce perceived UV
fluorescence brightness.
5. Packaging Specification Selection Guide
| Package Specification | Application Scenario | Suggestion |
|---|
| 500 g / metal can | Lab test, small‑batch proofing, formula evaluation | For trial‑test purpose |
| 1 kg / metal can | Standard trial & small‑volume production | Default MOQ unit, popular export package |
| 12 cans / carton (12×1 kg) | Medium‑volume mass‑production | Standard export carton packing |
| 20 kg / metal drum | Large‑scale continuous production | Contact sales for bulk price & lead‑time |
Tips
- Seal lid tightly right after opening to prevent solvent
volatilization and ink skinning.
- Do not mix with other ordinary offset inks.
6. Storage Conditions & Shelf‑Life Instruction
Storage Conditions
- Store in cool, dry, dark ventilated warehouse, temperature 10‑25 ℃.
Keep away from direct sunlight and UV‑light sources.
- Keep far from fire, high‑temperature heat sources, oxidizing
agents.
- Container must be tightly sealed after opening; prevent solvent
evaporation.
- 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
- Ventilation: Workspace must equip effective exhaust ventilation
system to remove solvent vapor.
- 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.
- Fire prevention: Solvent‑based ink is flammable. No open flame, no
spark sources nearby. Equip fire extinguisher in press room.
- Waste disposal: Waste ink, contaminated rags must be collected as
hazardous chemical waste, follow local environmental regulation.
- 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.

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.
