Official government documents demand uncompromising security features, robust durability, and efficient authentication. By integrating invisible markers, UV/IR elements, and high-resolution print fidelity, Nanografi Inks empower agencies to maintain public trust, safeguard sensitive data and deter unauthorized replication.

Security Printing for Government Applications
Government printing covers a wide range of documents that share one requirement: a person or a machine has to be able to tell a genuine document from a copy, quickly and in the field. That includes travel and identity documents, fiscal documents such as tax and duty stamps, and the everyday administrative documents — permits, licences, certificates, official forms — that carry legal weight but are produced in far smaller runs.
Security inks are the layer that makes this verification possible without adding a separate physical device to the document. The security travels inside the printed design, which keeps the cost per document low and allows a first-line check with nothing more than a UV lamp.
Government Documents and Authentication
Authentication in government printing is normally organised in levels, and a single document usually carries more than one of them so that defeating one reproduction technique is not enough:
First line (overt): checked by anyone, in daylight, without equipment. Visible inks carry the design, guilloche patterns and colour scheme.
Second line (covert): checked by a trained officer with a simple tool. UV offset security inks are invisible in daylight and fluoresce under long wave 365 nm or short wave 254 nm illumination.
Machine-readable: checked by equipment. IR security inks work through infrared absorption or reflection, outside the visible spectrum.
Forensic: bi- and tri-fluorescent formulations respond differently at different wavelengths, giving a laboratory a further level of verification when a document is disputed.
Relevant Security Ink Technologies
The right combination depends on the substrate and the printing system in use. Paper-based documents are printed with conventional oxidative-drying inks; polymer documents such as polycarbonate data pages and ID cards use UV curing security offset inks. Both systems can carry UV, IR, visible and thermochromic components, and screen printing security inks are used where a thicker, more heavily pigmented feature is required. See the full offset security ink portfolio.
Typical Applications
UV, IR and visible security inks are used across passport sheets, visa pages and polycarbonate data pages, supporting covert, overt and machine-readable verification. See passport and visa security printing.
ID cards and polycarbonate documents are polymer-based, so UV curing security offset inks are used, carrying UV fluorescence and IR response within a laminated construction. See ID card and polycarbonate documents.
Fiscal stamps are produced in very high volumes at low unit cost, so the security has to sit inside the printed layer and be verifiable in the field with a UV lamp. See tax stamps and excise.
Short-run documents with high individual value, usually verified by an institution with no specialist equipment. Covert UV features give a low-cost check. See documents of value.
Administrative documents that carry legal weight can be protected with the same covert and overt ink features used on higher-profile documents, without changing the printing process.
Currency and security paper printing uses conventional offset systems with UV, IR and visible components for layered verification. See banknote and security paper printing.
Why Security Inks Are Used in Government Printing
Verification without added hardware: a UV lamp is enough for a first-line field check.
Low cost per document: the security is inside the printed layer rather than in a separately applied device.
Resistance to photocopying and scanning: fluorescent and infrared responses do not survive reproduction.
Durability: rub resistance and lamination-friendly behaviour for documents that stay in circulation for years.
Layered verification: overt, covert, machine-readable and forensic levels within a single printed document.
