The ghost image includes optically variable media that has a first appearance when viewed from a front of the identification document in reflected light at a first angle and a second, different appearance when viewed from the front of the identification document in reflected light in a second, different angle. During the ghost image generation process, a graphical identifier can be placed on a baseline ghost image to generate an adjusted ghost image. Once the adjusted ghost image is printed onto the identification document, the graphical identifier can be viewable based on the appearance of the adjusted ghost identifier in relation to the reflected light.
