Abstract
A hybrid security device for security documents and the like, with the microstructure for a first optically variable device (OVD) and the microstructure for a second OVD mutually interlace or interspersed. The first microstructure has a height profile that differs from that of the second microstructure by more than 0.5 microns. Suitable fabrication processes for the hybrid security device are also disclosed.
