Complete range of security inks, fibres, and threads
WATER FUGITIVE INKS
Those inks have the particularity to react to water, hypochlorites, bases at 5%, acids at 5%, ink killer pens and so on. The effect is a discoloration or color alteration.
SECONDARY FLUORESCENT INKS
They are also water fugitive but they have another characteristic, they become fluorescent under UV light when they have been watered.
ERASABLE INKS
When the forger tries to Modify manually the document with an rubber, the erasable ink will be removed before the hand written mention showing the forgery.
REACTIVE INKS
Also called Solvent sensible inks, they react to Glycol Ethers, Benzenic solvents, Chlorinated solvents, Alcohol, Sulfuric Ethers, Gazoline and corrector by discoloration or color change.
FLUORESCENT INKS
INVISIBLE FLUORESCENT INKS
Fluorescence, invisible in daylight or artificial light, becomes visible when exposed to an Ultra-Violet light and does not producem as it is the case with phosphorescence, any after-glow (persistence of fluorescence after switching off the Ultra Violet light)
CHROMOTROPIC INKS
A chromotropic inks shows one color under normal light and another shade when exposed to UV light (for example brown PMS 168 fluorescent Green)
ANTI COPY INKS
The main color available is a very bright Orange that will turn either yellow or brown when copied.
VISIBLE AND FLUORESCENT INKS
When exposed to a UV light the copy is immediately detectable as there is no more fluorescence.
PHOSPHORESCENT INKS
Phosphorescent inks are not only fluorescent under UV light but after the UV light has been turned off, the ink remains visible during some time in the dark : this effect is called “after-glow”.
IRIDESCENT INKS
These inks are almost transparent when seen through but become colored when seen under a 45° angle.
PHOTOCHROMIC INKS
Those very specific inks can change their colour under the influence of relatively intense Ultra Violet light (Solar light, Photographic Flash, UV Light)
THERMOCHROMIC INKS
Those inks have the characteristic to loose their original colour when temperature is rising. This effect is always reversible.
VARIABLE REFLEXION INKS
These inks shades change according to the observation angle.
CONDUCTIVE INKS
These inks are especially formulated with specific pigments which give electrical conductivity characteristics to the final product.
COIN REVEALABLE 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.
WATERMARKING INKS
The print of these inks will give transparency to the paper, they are designed to imitate a Watermark on security papers.
SYMPATHETIC INKS
These inks are invisible when printed, but with the help of a specific revealer they become irreversibly colored
