Screen Printing Inks
Developed by Nanografi, Screen Printing Security Inks combine high-resolution printing with advanced anti-counterfeiting features. Formulated for high-viscosity screen printing processes, they create thick, clearly defined ink layers while seamlessly integrating security elements such as UV/IR-reactive pigments or invisible dyes. This makes them especially well-suited for critical applications like official seals, revenue stamps, and forensic (criminal) usage, where document integrity and reliable verification are paramount.
Key Features:
High Viscosity Compatibility
Produces thick, vivid ink layers for sharper details and more vibrant colors in screen printing.
Durable Formulation
Resistant to abrasion, heat, and chemical exposure, offering long-lasting protection against wear.
Multi-Layer Security
Incorporates UV/IR-reactive or invisible pigments, enabling multiple levels of authentication.
Easy Verification
Allows quick and reliable checks using specialized light sources or basic inspection equipment.
Wide Substrate Compatibility
Adaptable to various materials such as paper, plastic, and metal, ensuring flexibility in different security printing scenarios.
What Are Screen Printing Security Inks?
Screen printing security inks are inks formulated for the screen printing process, in which ink is pressed through a mesh stencil onto the substrate. Because screen printing lays down a considerably thicker ink film than offset, it is used in security printing wherever a heavier load of functional pigment or a more strongly defined mark is required.
Nanografi screen printing security inks are formulated for high-viscosity screen printing processes. They produce thick, clearly defined ink layers while integrating security elements such as UV/IR-reactive pigments or invisible dyes, which makes them suited to official seals, revenue stamps and other documents where verification has to be unambiguous.

Applications
Ideal for government agencies, corporations, or private organizations to produce tamper-proof seals and stamps.
Ensures secure printing for fiscal or tax-related stamps, reducing the risk of forgery or unauthorized duplication.
Aids in crime prevention and evidence security by providing verifiable features that deter counterfeiting.
Delivers multi-layered protection for badges, IDs, and other cards requiring stringent security measures.
With Screen Printing Security Inks, Nanografi elevates the screen printing process to meet rigorous security demands, delivering both durability and advanced protection for high-stakes applications.
How Screen Printing Security Inks Work
The security function comes from the combination of the printing process and the functional pigments carried in the ink film:
Ink transfer: the ink is pressed through a mesh stencil, depositing a thicker film than offset printing.
Film build: the thicker deposit carries more functional pigment, supporting a stronger UV or IR response and sharper definition.
Verification: the security features are checked with a specialised light source or with basic inspection equipment.
Durability: the cured film resists abrasion, heat and chemical exposure, so the feature survives handling.
Printing Considerations
Printing method: screen printing with high-viscosity formulations, not offset presses.
Substrate: adaptable to paper, plastic and metal.
Combination: applied alongside UV, IR and visible offset security inks where a heavier or raised feature is needed in the same document.
Feature selection: UV/IR-reactive or invisible pigments are chosen according to how the document will be verified in the field.
Why Nanografi
Nanografi was founded in METU Technopolis and operates as a subsidiary of Ahlatcı Holding, with international operations across more than 100 countries.
Nanografi Inks develops formulations through a defined process: assessment of requirements and application scope, formulation design according to substrate and curing behaviour, testing and validation under application-specific conditions, and production with continuing technical support.
Frequently Asked Questions
They are security inks formulated for the screen printing process, where ink is pressed through a mesh stencil. The thicker ink film allows a heavier load of functional pigment and a more strongly defined printed mark than offset printing.
Offset security inks are formulated for offset presses and produce a thin ink film at high speed. Screen printing inks are high-viscosity formulations that deposit a much thicker layer, which suits raised or heavily pigmented security features.
Nanografi screen printing security inks can incorporate UV/IR-reactive pigments and invisible dyes, enabling multiple levels of authentication within one printed area.
They are used for seals and official stamps, revenue and tax stamps, forensic applications, ID and card systems, and labels and packaging.
The formulations are adaptable to paper, plastic and metal, which gives flexibility across different security printing scenarios.
Verification is carried out with a specialised light source such as a UV lamp or an IR reader, or with basic inspection equipment, depending on which functional pigment is used.
