High-security printing applications refer to the printing of banknotes, postage stamps, cheques, passports, identity cards, seals and any other document where security is a main concern. Naturally, the objective of security printing is to prevent criminals from counterfeiting or tampering with important documents and at the same time improve the aesthetics of those.
Unique documents such as government IDs or currencies require multiple security printing techniques to ensure their security and effectiveness.
There are many different technologies used to protect valuable documents for example special intaglio printing, security threads, holograms, microprinting, and a wide range of security inks!
As Luminochem focuses on developing high-end security pigments, its products are used in many different high-security printing applications around the world. Obviously, discretion is very important for our clients, so we cannot name the specific currencies that use our products in their security features, but we can say that the pigments used provide an exclusive special-effect for making the notes more easily verifiable and to guarantee anti-counterfeiting security.
In general, products with exceptional qualities (light fastness, chemical stability etc.) are the most used in high-security printing applications.
Special effect inks using Luminochem pigments can be incorporated into hidden texts, marks and images and, whilst not visible under normal white light, can be easily verified using ultra-violet light (UV‑A, 365 nm or UV‑C, 254 nm) or a special luminescence detector.
As we can produce pigments of high fluorescent intensity with a very fine particle size Luminochem pigments are suitable for use in offset, flexo, gravure, screen and intaglio printing techniques. The vividness of our proprietary water soluble and organic solvent soluble fluorescent dyes means they are suitable for use in inkjet printing applications at around 1% concentration. We produce three types of NIR absorbing materials: solvent soluble, water soluble and insoluble.
