Contact sales for bulk price & lead‑time |
Tips:
- Open small‑quantity 1 kg can for daily use, keep big drum sealed tightly to prevent skinning.
- Each metal can with inner anti‑leak lid for safe international shipment.
Storage Conditions
- Store in cool, dry, ventilated warehouse, temperature: 10‑25 ℃
- Keep far away from fire source, direct sunlight, high‑temperature environment
- Seal the lid tightly after opening; avoid long‑time air exposure to prevent ink skinning.
- Keep away from oxidizing agents.
Shelf‑Life
- Unopened original package:12 months from production date
- After opening:Use‑up within 3 months; filter before reuse if skin sediment appears.
Warning:Expired ink may cause unstable magnetic signal and bad printing effect, do not use for security‑grade production.
Magnetic Strength Grade(磁性等级)
表格
| Grade |
Magnetic Signal |
Application |
| Standard(本品默认) |
Clear trigger by magnetic test pen |
General anti‑forgey document, ticket, label |
| Enhanced(Custom option) |
Strong magnetic response |
MICR machine‑readable requirement; contact sales for customization |
Note:Red color magnetic pigment has slightly lower magnetic particle content than black / brown magnetic ink; if you need MICR high‑strength reading, choose enhanced‑grade version.
Test steps:
- Print ink on target substrate and fully dry.
- Power‑on magnetic detecting pen.
- Sweep pen head slowly across printed graphic.
- Qualified: pen triggers light / beep alarm; unqualified: no response.
| Authentication Method |
Test Tool |
Performance of this Red Magnetic Ink |
| Naked‑eye visual check(肉眼) |
Human eyes |
Visible bright red printing color, normal appearance; no hidden visual feature by bare eye |
| UV 365nm(紫外检测) |
365 nm UV lamp |
No UV fluorescence (this is pure magnetic ink, no UV luminescent pigment) |
| IR Infrared(红外检测) |
IR detector |
No special IR absorb / reflect property |
| Magnetic detection(磁性检测,core feature) |
Magnetic test pen / MICR magnetic reader |
Dry printed area can trigger magnetic pen alarm; Enhanced grade supports MICR machine reading |
Recommendation:If multi‑layer anti‑forgey required, mix‑print with UV‑fluorescent ink / infrared ink together.
8.Application Scenarios & Case Display
- Banknote & Financial documents:Anti‑forgey mark for checks, tax stamps, financial voucher；enhance document security against forgery.
- Certificate & ID documents(证书证卡):Diploma, qualification certificate, membership card, passports anti‑forgeymarking.
- Ticket industry(票据票证):Transport tickets, lottery, event admission tickets, anti‑forgey hidden magnetic mark.
- Packaging anti‑forgey(包装防伪):High‑value goods box, wine packaging, luxury label; covert magnetic mark for brand anti‑forgey.
Case brief:Several security printing factories adopt Ceres red offset magnetic ink for high‑end certificate covert magnetic marking; only detectable by magnetic pen, difficult forforgey to replicate.
FAQ
Q1: What is minimum order quantity? A: MOQ is 1 KG. 1 kg metal can is trial‑order unit; bulk order available at discounted price.
Q2: What is production lead‑time? A: Stock color (Red / Black / Brown / Yellow): 3‑5 working days after payment. Custom magnetic‑strength formula: 7‑10 working days.
Q3: Can you provide customization service? A: Yes. We support customize magnetic strength, adjust viscosity for special press, special color matching. Send your printing requirement for technical evaluation.
Q4: What are available shipping methods? A: As solvent chemical ink, international shipping by FedEx / DHL special chemical channel. Domestic by land freight. Freight cost depends on weight & destination
Q5: Can I get sample? A: 100‑200g sample is available; sample fee and freight will be charged. Sample fee can be refunded when formal bulk order reaches certain quantity.
Q6: Why magnetic pen gives weak signal on plastic film? A: Mainly two reasons:①Ink not fully through‑dry；②Plastic surface energy insufficient. Cure longer time or do corona treatment for plastic substrate.
Q7: How to clean offset press after using magnetic ink? A: Use offset solvent washing agent to clean roller, blanket and plate thoroughly; magnetic pigment residue may cause next‑job contamination if uncleaned.
