on printed documents
Written by : N.R. Jayaraman
This article spread over to three or four parts discuss the
nature of security features found on the security documents
and other commercial documents of various kinds.
addition to the standard features which have been discussed as mentioned earlier I have reproduced for
educational purpose, brief on certain security features developed and owned as proprietary products by some of the reputed firms. For more details the concerned firms should
only be contacted.
18) Opsec Security has developed an unique security feature called liquid crystal technology to create a range of highly specialized OVD security products that provide overt, covert and forensic protection into a single image. Advantage™ which can be customized to any logo for brands is available in a variety of constructions for multiple delivery systems, providing excellent optical authentication and tamper evidence. In normal lighting conditions, both daylight and artificial, the image appears green to orange, depending on the viewing angle.
The firm claims that the unique tri-modal color-shift technology is easily verified yet cannot be reproduced by even the most sophisticated duplication technology such as printing, photography or color photocopy. The product is reportedly represented by SecurMAX™. To read more on this product visit their site by clicking:
19) M/s Kodak Ltd, pioneers in the photographic field has also come out with a special feature called KODAK TRACELESS Color Shifting Inks. Available in seven color pairs, KODAK TRACELESS Color Shifting Inks provide an overt authentication feature. These inks are made with special pigments that change color as the viewing angle changes. Available in seven eye-catching color pairs it can be the security feature for the packages, labels and documents . Color shifting features can be used on a solid black background, white background or gradients. Multiple layers of security is applied in a single step when used in combination with KODAK TRACELESS Markers. To read more on this product visit their site by clicking:
20) INKSURE taggants mixed with the ink can be applied to every medium like polymeric foils, plastics, paper, natural/synthetic fabrics, metal, glass, wood, ceramics and more. The exceptional durability of INKSURE taggants can withstand harsh wear-and-tear conditions. The presence of the taggant in the print can be verified by a custom prepared hand held device. This feature is reportedly used in flexographic printing for pharmaceutical product labels and on their cartons. To read more on this product visit their site by clicking:
21) As a banknote and security paper manufacturer, Giesecke & Devrient has introduced innovative security features such as the following.
- FEEL called Fast Energy Effective Inks (Special Effect Inks) is an interactive security feature for banknotes. The printed color undergoes a clearly visible color change as soon as it is exposed to heat. The warmth of your
fingertip is enough to alter the color at a specific location on the
PEAK called Printed Embossed Anti copy Key (Intaglio printing) combines offset and intaglio printing. Fine lines produced in a special engraving method are embossed to produce a three- dimensional, optically variable image. The color and information changes according to the viewing angle and light direction. Users can feel the tactile embossing with their fingers. These effects cannot be replicated by a color copier.
FIT latent (Intaglio printing) – the new generation of latent images offers
digital image flip on a 3D background.
Tilting the banknote changes the image, making two different motifs
- FIRST (Covert security features) uses a laser to create hidden codes on the printed banknote. These are invisible to the human eye and can only be read under an infrared light.
- STEP called Shimmery Twin Effect Protection (Special Effect Inks) is an optically variable ink that produces two different color effects from different viewing angles.
- FIT called Fine Intaglio Technology (Intaglio printing) is the first-ever steel engraving method that can produce ultra-fine lines. This high-resolution technology enables the creation of novel security features that are unparalleled in terms of design and quality.
- LOOK (Laser Marking) is a laser marking method that uses ultramodern laser technology to individually adapt established security features and thereby create new ones.
- Using the feature – known as INFACIO – passport photographs and text can be protected against tampering. According to the company: “Each passport holder’s personal data can be printed in the passport using a special ink that remains invisible in normal daylight, but which can be revealed under ultraviolet lighting.
