“Rolicure™ Pearl”: An Optically Variable Device for Security Applications
Abstract:Recently, we developed a novel optically variable security feature Rolicure™ Pearl. We report about its successful transfer from laboratory scale into manufacturing. While the origination work of Rolicure™ Pearl is based on ROLIC's proprietary photopolymer- and their processing technologies, its reproduction is performed on adequate equipment. Ideally, this new optically variable device (OVD) is manufactured as a foil product for use in hot-stamping, lamination or as self-adhesive labels.
Rolicure™ PEARL devices exhibit brilliant, easily recognizable, high-resolution images, which switch from positive to negative when tilted or rotated. Even under demanding illumination conditions and within wide-ranging viewing angles Rolicure™ Pearl images can be unambiguously revealed and identified with the naked eye. Although individual images can be of complex structure, the optical effect is straightforward and, hence, the verification process is easy to communicate. Being an overt device by itself, Rolicure™ Pearl can easily be combined with covert features or tampering protection. Its uniqueness, its high level of protection and its cost effectiveness make it most suitable for application on fiduciary- and ID-documents as well as in high-end brand- and product protection.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
