O.V.M™ Fiduciary inks
innovative and flexible security
for ID documents
Currently, document manufacturers face the challenge of securing the transparent areas of the ID documenst to level 1. Commonly used security inks, while representing a ready-made solution, are frequently the target for counterfeiting. Moreover, they are also used in other areas such as cosmetics. These inks have thus partially lost their efficiency in terms of security.
C.S.T introduces O.V.M™ "Optical Variable Material" technology that secures the printing of ID documents.
This technology is different from what is used for conventional security inks. It is exclusively dedicated to the area of ID and fiduciary documents.
O.V.M Fiduciary Inks are mainly applied on the windows of ID documents. They allow the application of innovative and intuitive security features. They dote the printed patterns with previously unknown visual effects that are observable in level 1, 2 and 3.
O.V.M Fiduciary Inks are high security features available in several color shifts. They open the door to new design possibilities. These pigment-free inks have an exceptional durability compared to inks commonly used on ID documents and banknotes. Their application is naturally very flexible and their integration is possible without any modification to existing printing processes.

Level 2 allows authentication with a standard control device like UV lamps. They are common at border posts. The printed pattern on the transparent area shows a very strong fluorescence under UV light.
O.V.M Fiduciary Inks offer a very innovative and intuitive visual effect: the pattern printed on the transparent area of the ID document changes color according to the color of the background on which it is displayed. For example, the printed pattern appears Blue when viewed on a light background; it turns Red on a dark background. It is an innovative security feature, highly intuitive and easy to remember.
O.V.M Fiduciary Inks create a new level of intermediate verification between level 1 and level 2. This new level is observable thanks merely to equipment readily available to the general public: the flashlight of a smartphone (or any other conventional white light source). For example, in the light of a smartphone flashlight, the pattern printed on the window of an ID card turns Red while its projected shadow remains Blue.
Level 3 is controlled with laboratory equipment. Each O.V.M Fiduciary Ink is identifiable by a unique spectral DNA. It can be certified by C.S.T labs.
