Counterfeiters are in trouble…The days of counterfeiting are gone with the new authentication technologies
Leonhard Kurz has improved its diffraction authentication technology. It has further improved its Trustseal authentication technology. The specialist in optical authentication technology has fitted the OVD (Optical Variable Device, an optical variability device) system with new technologies, capable of defeating the best counterfeiters.
The Trustseal OVD systems can be fitted with various specific features, as required by the customer and the security level specifications. This does not only involve lenticular technologies and raised and contrast effect, but the hidden technologies only visible at certain angles or under great magnification. With the great composition flexibility and strong functional potential of the Trustseal technology, it has become possible to integrate continuously new security features into the OVD systems of the Trustseal technology, hence increasing the strength and ever more complex barrier against counterfeiters.
According to Kurz, its new PM Premium technology provides an outstandingly high level of protection against forgery. PM Premium is a range of products presenting a simulated raised surface, combined with more diffractive elements and transparent areas. The partial metallisation process applied to graphic elements represent real challenges at manufacturing levels, which can only be overcome by the utmost know-how. Kurz is very happy with its high-precision partial metallisation achieved through its PM Premium technology, thanks to which sophisticated metallised designs have been integrated as a grid, with non-metallised areas, and a hardly visible tolerance.
The Trustseal technology encompasses a new element called Latent Photo. This technology outputs a grey-scale gradient image under normal viewing mode. However, when the OVD system is turned upwards or seen under a significant oblique view, the grey-scale picture then becomes a vibrant coloured image. It then also becomes possible to integrate another inclination angle so that the coloured photo only appears in third position. Under normal viewing angles, the background is a large, grey-scale image over which is superimposed a strongly coloured picture. When at an angle towards the right or the left, another picture is displayed featuring other colours. The colour photograph appears in the third position when the OVD system is turned upwards and seen at a significant oblique angle. The Latent Photo effect can be used not only as a safeguard against counterfeiters, but also viewed as an exquisite design element. Any type of photograph can be used for the Latent Photo effect, such as celebrity portraits, the representation of well-known monuments or pictures referring to the manufacturer or the product.
A third innovation provided by the Trustseal effect: Bottle Neck. As for the Latent Photo effect, it combines brand protection and sophisticated brand identification. The Bottle Neck effect was specifically developed for seals on bottles. When the OVD systems are applied to curved areas, such as a bottle neck, the full effect of the opalescent, diffractive décor can only be seen on a narrow strip of the area. However, the diffractive Bottle Neck structures have been designed so that the décor appears in a clear and colourful way over the whole width, and the information is accessible at a glimpse.
