A security document includes a security feature with a hologram and a color image arranged on top of each other. Holographic features of the hologram are visible when the security document is viewed under white light, and a plurality of image features of the color image are visible when the document is viewed under UV light. The image features are perfectly aligned with the holographic features. This can be achieved, for example, by providing one or more registration marks when forming the holographic features, and using said registration marks to later print the color image. Another possibility is to use the structure of the hologram to selectively apply two or more UV-sensitive ink materials onto the hologram to automatically align the same with the holographic features.
