2026-08-04 published · updated
SJH UV invisible black ink: milky white in daylight, reveals fluorescence under UV — for covert marks on cigarette labels.
UV invisible ink is a standard choice for cigarette package security thanks to its covertness, easy verification and controlled cost.
Advantages
Colorless in normal light, invisible to the naked eye, UV invisible ink reveals fluorescent patterns only under a 254/365nm UV lamp. Consumers verify with a currency detector while counterfeiters can hardly spot the mark, greatly raising the copying difficulty.
Typical Applications
Covert fluorescent patterns and text on cartons and packs
One-code-one-item covert coding with inkjet printing
Combined with OVI ink for a dual-layer defense
Plus thermochromic ink for a three-layer system
SJH Ink supplies UV invisible ink for cigarette package printers, with free printed proofs. Tel: 13510998453.
Frequently Asked Questions
Selection, detection, printing and ordering — answered.
Why is UV invisible ink so common on cigarette packs?
Because it is covert, quick to check and cost-controlled. Invisible under normal light, it appears only under 254/365 nm UV. Consumers can verify with a banknote detector or UV torch, while counterfeiters often do not realise the mark exists.
How is UV invisible ink actually applied on cigarette packaging?
Four common patterns: covert fluorescent patterns and text on cartons and packs; identity codes printed with inkjet for traceability; combination with OVI for a two-layer defence; and a third layer of thermochromic ink on top.
In an OVI plus UV combination, what does each layer do?
OVI handles overt security — tilting the pack shows a colour shift with no equipment. UV handles covert security, appearing only under a UV lamp. One visible, one hidden, so breaking one layer still leaves the other.
Will it suit high-speed cigarette packing lines?
Yes. UV invisible ink runs on offset, screen and flexo — the mainstream cigarette packaging processes — with strong adhesion and heat and weather resistance for high-speed lines.
How far can UV invisible ink be customised for cigarette packs?
Fluorescence colour (red/yellow/green/blue) and excitation wavelength are both customisable, with adjustable intensity to balance graphic design and security. Printed proofs can be supplied for a press trial first.
