“Rolicure™ Pearl”: An Optically Variable Device for Security Applications
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 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
