Detailed Description
NanoMatriX International Ltd. provides a wide range of security inks, which can be customized to meet specific security requirements. Here is a selection of the security inks we provide.
Anti-copy Inks
The main color available is a very bright Orange which will turn either yellow or brown when copied.
Anti-stokes Inks
Once printed, the ink is totally invisible and will react in 3 possible shades when excited with the help of an Infrared Laser emitting at 980 nanometers.
Black paint Inks
This range of inks is black colored. Once dripped with a little bit of water or simply spread with a wet finger, the ink becomes colored. This effect is called "bleeding".
Coin revealed Inks
The ink is totally invisible, and in order to reveal the printing, a coin of copper or brass is gently rubbed on the invisible printed ink and the printed message will appear in grey.
Color changing Inks To Top
These inks change color according to the observation angle.
Conductive Inks
These inks are formulated with specific pigments which provide electrical conductivity characteristics to the final product.
Erasable and Reactive Inks
When the forger tries to modify manually the document with a rubber, the erasable ink will be removed before the hand written mention showing the forgery.
Iridescent Inks
These inks are almost transparent when seen through but become colored when seen at a 45º angle.
Pearlescent Inks
These inks will give a white pearlescent aspect that cannot be reproduced by either photocopiers or scanners.
Phosporescent Inks To Top
Phosphorescent inks are not only fluorescent under UV light but, after the UV light has been turned off, the ink glows for some time in the dark: this effect is called "after-glow".
Photochromic Inks
These very specific inks change color under the influence of relatively intense Ultra Violet light (Solar light, Photographic Flash, UV Light).
Reactive Inks
Also called Solvent sensible inks, these inks react to Glycol Ethers, Benzenic solvents, Chlorinated solvents, Alcohol, Sulfuric Ethers, Gazoline and corrector by discoloration or color change.
Secondary Fluorescent Inks
These inks are also water fugitive with the further characteristic that they become fluorescent under UV light when they have been watered.
Sympathetic Inks
These inks are invisible when printed, but with the help of a specific revealer they become irreversibly colored.
Thermal Inks To Top
In opposition to Thermochromic inks, these inks, are invisible after printing but become irreversibly colored when exposed to a high temperature.
Thermochromic Inks
Those inks have the characteristic to loose their original color when temperature is rising. This effect is always reversible.
Visible and Invisible Fluorescent Inks
When exposed to a UV light, the copy is immediately detectable as there is no more fluorescence.
Water Fugitive Inks
These inks have the particularity of reacting to water, hydpochlorite, bases at 5%, acids at 5%, ink killer pens, ethanol benzene 50/50, oxydoreductor, sodium sulfite, glycol ethers and alcohol. The effect is a discoloration or a color alteration.
Watermarking Inks To Top
The print of these inks will give transparency to the paper, they are designed to imitate a watermark on security papers.
Applications
In most cases security inks will be the first choice to prove value, validate identity, authenticate products or track movements for the following reasons:
- Capability contain over, covert, forensic, and track & trace features,
- Cost efficiency
- Usability on almost any substrate and in harsh environment
- Compliance with nearly all available printing technologies.
Security inks are typically printed on paper or plastic substrate based security documents. However, recently developed ink formulations help to further elevate their application to authenticate products and/or track product movements. New ink formulations have been developed which allow the use of security inks on substrates or in harsh environments where security inks could not be used before. Also, considerable progress has been made in the field of marking and coding, which open multiple opportunities in product tracking and tracing.
