Precision vacuum reflective layer deposition
Security holograms can have several reflective layer aspects thanks to vacuum-coating technologies: transparent, aluminium, copper, chrome, and special colors.
HRI is a special reflective coating technique that leaves the optical image completely transparent and very bright. It is used notably in identity document protection systems since it enables both authentication of the document and protection of the variable data covered by the image, without impacting its readability. HRI technology requires specific equipment and know-how.
High definition Reflective Layer Shaping
SURYS masters technologies enabeling to micro-shape the reflective coating.
The Shaping is done in tight registration with the visual optical image, thus enriching the optical security design. The very high definition achieved can be used to create reflective micro text or micro images. Few companies in the world master this technology. Its combination with certain optical and specific refelctive technologies guarantees an additional level of security.
SURYS masters high-definition printing (micro-letters, lines) on optical images, in particular the combination of special security inks with optical images, including luminescence photo, taggants, thermo reactions, etc.
Depending on the special inks or varnishes to be used, the printing may be visible or invisible (in this case a special reader is needed, such as an UV lamp or a luminescence reader).
With proven additional expertise in high-quality flexo printing, SURYS can combine security and functional printing with customers’ graphic appearance.
