Security Inks

Secure inks are used as an added security feature for the protection of printed documents, labels or packaging against fraudulent reproduction or counterfeiting. There are many different types of security inks used for this purpose depending on the application, environment, required level of security.

Veritech offers numerous security inks that are highly effective in protection against the menace of counterfeiting. We recommend different inks for different applications where both covert and overt printing solutions are required for packaging, labels or holographic seals to help protect brands and consumers from fake products. Some of our inks also employ forensic technologies that can be seamlessly integrated with our wide range of brand security products.

Types of Security Inks

UV printing (View Demo)

These are high security inks that are invisible under normal lighting conditions, but under UV light, these glow in a bright colour. The UV LED’s used to read the message written by UV markers emit near-ultraviolet light. When the black light is made to fall upon this UV-visible ink, it makes the ink fluorescent, thereby making the message readable by human eyes. Variable information can be printed on the Hologram using UV inks which are visible only through a UV light source.

This helps in second stage authentication & also in tracking goods throughout the chain of distribution in a covert manner. Invisible UV inks are available in different frequencies and a multitude of colours.

Thermochromic (View Demo)

These are temperature sensitive inks which change colour with a change in temperature (for instance, by rubbing) – The printed text / image appears or disappears when rubbed by a finger or on application of any heat source.

Coin Reactive (View Demo)

These inks react when they come in contact with coins or other metallic objects. When the printed area is rubbed with a coin, it blackens to reveal the hidden text or image. Thus, it acts as an instant authentication tool and is also end user friendly, as no separate device is required for authentication.

Fluorescence (View Demo)

These inks are visible as lighter shades of colour under normal lighting, but when exposed to UV light, these will exhibit different colours of fluorescence depending on the wavelength of the light.

Texture Varnish

Selectively applied varnish creates controlled repellence if solid areas are overprinted with a liquid gloss varnish. This controlled repellence is characterized by the formation of fine droplets, which add a textured effect to the printed material. The unique texture can be used as a security or aesthetic tool.

Cast & Cure

Also known as Film Casting, Cast and Cure is a cost-effective and environmentally-friendly printing technology that produces high-gloss, holographic effects by using various specialty films and UV coatings. Cast and Cure adds an excellent visual impact to packaging, and can also be customized with anti-counterfeiting features for brand security.

Another key advantage of Cast and Cure is that it can be spot applied to enhance specific areas on the label or packaging.

Solvent Reactive / Water Reactive (View Demo)

These inks are particularly useful in protecting documents with variably printed information, such as cheques and other financial or legal instruments. When exposed to certain solvents like alcohol, acetone or bleach, these inks will undergo a chemical reaction which will cause them to run, change colour, or leave a stain, hence indicating that the document has been tampered with. Water reactive inks exhibit similar properties when they come in contact with water based fluids.

Optically Variable Ink (OVI)

Optically variable ink is a highly secure anti-counterfeiting ink which finds use in many modern currencies as well as in other critical documentation. The ink displays two distinct colors depending on the angle it is viewed from. It has a very high level of security since it is not widely or easily available, and one has to go through stringent checks and procedures to obtain the same. These inks have color-shifting properties due to which they reflect various color wavelengths in white light differently, depending on the angle of incidence to the surface.
