Security printing utilises security inks to minimise/curb counterfeiting. These inks are cost-effective, relatively easy to apply, and provide an excellent base for some of the most advanced covert applications such as DNA markers and taggant integration. They are extensively used on labels and containers for primary, secondary and tertiary packaging and they are formulated for almost all substrates. The images/text created by security inks are not visible by naked eyes and they can be viewed only with the help of hand-held gadgets like talking pen, taggant reader, UV torch etc.
Holostik provides a wide range of product based solutions and these include a combination of anticounterfeiting products and IT-based solutions; thereby bridging the gap that existed when they were applied on the product/documents independently.
Following are the different types of security inks used by Holostik.
- UV or invisible ink – These inks also known as security inks and are used due to their property that when applied they are invisible either on the application or soon thereafter, and can later be made visible by UV light.
- Fluorescent ink – This ink is colourless, transparent, or white and can be easily detected under UV light.
- Thermochromic ink – This ink is visible only when given heat.
- Photochromic ink – This ink is visible under sunlight only.
