SJH UV fluorescent red ink: milky white in daylight, reveals red fluorescence under UV — for cigarette and document security.
Anti-counterfeit inks are key to multi-layer security systems. OVI ink shifts between two colors by viewing angle and is hard to replicate; UV fluorescent ink is colorless under visible light and reveals fluorescence under UV; IR excitation ink requires special devices to verify, offering the highest security level. SJH Ink can combine multiple technologies for cigarette packaging, documents, tickets and brand protection.
Frequently Asked Questions
Selection, detection, printing and ordering — answered.
What role does security ink play in a multi-layer protection system?
It is the most basic and most widespread carrier. Printed onto packaging or documents, security ink leaves the existing design untouched while giving the product the ability to prove authenticity, and it stacks with guilloche patterns and security codes into a layered defence.
How do OVI, UV fluorescent and IR excitation inks divide the work?
OVI shifts through two colours with viewing angle and is very hard to copy, so it carries overt protection. UV fluorescent ink is invisible in normal light and glows under UV, giving covert protection at consumer level. IR excitation ink requires dedicated equipment, which places it at professional level.
Which combinations suit cigarette packs, documents and tickets?
Cigarette packs typically use UV invisible plus OVI for covert and overt cover, optionally with thermochromic as a third layer. Documents favour a graded stack of IR excitation, OVI and covert UV by detection threshold. Tickets lean on UV fluorescent plus IR, balancing machine reading with manual checks.
Can several security inks be combined?
Yes — and that is standard professional practice. SJH can combine multiple security technologies to deliver a complete solution for cigarette packs, documents, tickets and brand protection.
