“Everything should be made as simple as possible, but not simpler”. – driven by this famous Einstein principle, we have developed a new security feature with a clear visual effect and simple identification. 3D-GRAM® CONTRUST is a photopolymer security patch with a colour-changing effect. When the element is rotated by 180°, the colour of the images switches from red to green and vice versa. Such dynamic colour-changing effect captivates the public while an unambiguous colour contrast leaves no doubt about the banknote authenticity.
The modern world imposes new rules for banknote security. Central banks vote for high-tech security features to exclude imitation and forgery by widespread copying methods. Besides, these technically advanced security features should go together with catchy visual effects and clear identification, which are easy to communicate to the public. The 3D-GRAM® CONTRUST security formula contains the vital components of a security feature everyone can trust. That is an innovative material, cutting-edge technology, and a robust visual effect.

“We work hard on photopolymer security elements, testing various visual effects and product formats. For example, last year KRYPTEN launched a composite photopolymer 3D-GRAM-C® security stripe with demetallized images. For the new security feature, the goal was to find out both robust and cost-effective solution. Based on the unique characteristics of the photopolymer material, we realized a visually appealing and self-explanatory security effect. The high spectral selectivity and a wide dynamic range of the photopolymer make it possible to create structures that restore different colours in mutually orthogonal planes. As a result, we have got a striking colour-changing effect, which is visualized when the element is rotated by 180°. Such clear visual effect and distinct colour contrast of our new 3D-GRAM® CONTRUST security patch ensure that users can accurately identify the banknote authenticity”.
Andrey Smirnov, Head of Holographic Laboratory
The 3D-GRAM® CONTRUST patch captures contour portraits of Dennis Gabor and Albert Einstein along with the Nobel Prize anniversaries. The mirror composition of the elements perfectly displays the colour-changing effect of the new security feature. By turning the banknote 180°, a person can easily identify the colour change of the upper and lower elements. Images turn from red to green and vice versa. For the patch, we chose a classic pair of red and green colours. Still 3D-GRAM® technology allows you to reproduce images in various colours and select colour combinations to integrate the feature into the design of each banknote. For example, you can use a pair of blue and yellow, or other combinations. However, mixed colours are less obvious and not so easy for users to remember and we recommend using traditional pure colors for more secure authentication.

Designing Banknote – Prominent Effect for Prominent Scientists
2021 marks two important anniversaries for holography. 50 years ago, in 1971, the Hungarian physicist Dennis Gabor received the Nobel Prize "For his invention and development of the holographic method". And 100 years ago, in 1921, the greatest scientist of our time, Albert Einstein, became the winner of the Nobel Prize in physics. The prize was awarded to Einstein for the discovery of the law of the photoelectric effect.
The theme of the Nobel laureates fully matches the concept of our new 3D-GRAM® CONTRUST security patch. Two significant discoveries, two anniversaries perfectly reveal the security effect of the new element.
For the 100/50 Nobelists note, we chose a vertical orientation and mirrored the portraits of Gabor and Einstein on the obverse. Such a design composition, featuring portraits of two great scientists, breaks the stereotypes of banknote graphics and singles out the 100/50 Nobelists design concept from conventional standards.

The abstract composition next to the portrait of Dennis Gabor symbolizes holography. The hand on top represents the real object that touches the photo material. And below is a recorded virtual image of the hand, that is, a hologram. Multi-coloured rays and laser beams convey the nature of light and colour.
To the right of the portrait of Albert Einstein, the principle of the photoelectric effect is schematically depicted. When light interacts with matter, the photon energy is transferred to the electrons of the substance, and the electrons are released from the surface of the body. Below is a concise formula, which the scientist explained the photoelectric effect.
The reverse of the banknote depicts the moment of the Nobel Prize Award Ceremony. Prestige and recognition come off the fingertips of the public, which applauds the achievements of modern science. The goddess of Nature and the genius of Science become witnesses of the triumph of human knowledge. This composition with the goddess emerging from the clouds is depicted on the medals in physics, which are awarded to Nobel laureates. Around the circumference, there is an inscription in Latin “Inventas vitam juvat excoluisse per artes”, which literally means “It is beneficial to have improved life through discovered arts”.
