Abstract: Identification devices and methods of producing the identification devices are presented. Some embodiments of identification devices comprise a structure having a micro-optic image and a layer that is overprinted onto the surface of the structure. In some embodiments, the structure is a substantially planar structure, such as a cardstock sheet, and the micro-optic image is a hologram. A web-fed flexographic printing process is presented, in which the process comprises the steps of providing a web, determining a feed rate for the web, feeding the web at the determined feed rate, and overprinting onto a surface of the web. In some embodiments, the web has a micro-optic structure and an eye-mark. The micro-optic structure is located at a predefined position on the web, and the eye-mark is located at a fixed position with reference to the position of the micro-optic structure. The feed rate is determined using the eye-mark. In some embodiments, the micro-optic structure is a hologram.
