RollingStar^® Venus threads are cutting-edge security features for banknotes and secure documents. They address the growing risk of counterfeiting, which has become more prevalent as traditional color-shifting threads have become more widespread and less distinctive. While current two-color solutions based on lens technology primarily provide decorative effects with limited security, RollingStar^® Venus offers a new level of protection through advanced nanotechnology combined with micro-mirrors and thin-film ColorShift^TM effects.

These threads feature two sharply defined colors and dynamic optical effects, including the unique ColorFlip^® feature, which allows the color and motif to change within the same area. This creates a memorable and highly secure appearance. Micromirror technology provides brilliant, visible dynamic effects under all lighting conditions, and the metallic gloss enhances the perceived value of documents.

RollingStar^® Venus threads support fundamental thread properties such as customizable clear text, durable embedding in paper, and application of the next generation of magnetic encoding (MultiCode™). RollingStar^® Venus threads are coated with adhesive on both sides for perfect bonding to the substrate. For even better perception, registered embedding is also possible.

The design of the RollingStar^® Venus “Hummingbird” House Note celebrates the captivating, radiating color dynamics of the Venus ColorFlip^® effect, embedded within a lush natural environment on both the front and back of the note. Nature is not used as decoration, but as a narrative tool – guiding the viewer instinctively toward movement, light, and authenticity.

On the front, a hummingbird hovers in mid-flight, drawn to the sweet nectar of blossoms. Its slender beak naturally directs the viewer’s gaze toward the security thread, where shimmering, multicolored blooms appear to grow directly from the tropical setting. The RollingStar^® Venus security thread becomes a living element within the scene, forming a vertical axis that frames the composition and invites interaction. When the note is tilted, the Venus thread reveals dynamic color shifts that visually echo the bird’s suspended motion, reinforcing the idea that life is revealed through movement.

These dynamics are not only aesthetic. They are generated by secure micromirrors combined with nanotechnology that is precisely engineered to produce strong, intuitive optical effects. The result is a feature that is instantly recognizable and easy for the public to authenticate, yet difficult to imitate. Its beauty and clarity encourage natural verification at first glance, turning authentication into an engaging, almost instinctive action.

The narrative continues through the blossom watermark. Hidden within the paper, the flower only emerges when held up to the light. This reflects nature’s logic that true value is subtle and layered and is revealed only under the right conditions.

Together, the security thread and watermark tell a coherent story where motion reveals life and light reveals truth. Security becomes an integral part of the visual experience rather than a technical addition.

RollingStar® Venus threads enhance security through novel nanotechnology, an art and science enabling microscopic structures to deliver entirely new dynamic effects for intuitive authentication. As the latest addition to the RollingStar® family, they preserve all proven security properties while adding advanced nano-enabled features.

Viewed straight on, they present a secure, ultra-precise and visually striking two-color appearance. When tilted, they reveal the highly dynamic synchronization of color and movement – the ColorFlip™ effect in this housenote represents this feature brilliantly.

– RollingStar® Venus provides optimal visibility in challenging lighting conditions.  The technology ensures superior visibility across various lighting conditions. With micromirror technology that reflects up to 90% of light and a metallic surface finish, it stands out in terms of brilliance and clarity, and captures the users’ attention with the second color.

– Individual demetallized designs. Demetallized text (ClearText) is available for RollingStar® Venus security threads to create customized designs, including denomination or country-specific elements. Therefore, additional security is provided by showing different information in reflected and transmitted light.

– Level 2 features. Even more secure when combined with machine-readable Level 2 features. That’s why RollingStar® Venus incorporates magnetic coding for high-level machine readability and can be equipped with fluorescence as well.
