Abstract
Security features used on identification documents such as plastic cards and passport pages are described. The security features include a textured portion that is formed on a portion of the surface of the identification document using a laser. The security features can also include a printed portion and/or a laser marked portion. The printed portion (if present) can be formed above or beneath the textured portion. The laser marked portion (if present) is formed within the thickness of the identification document below the textured portion. The textured portion and the printed portion and/or the laser marked portion can be in congruence with one another to form the security feature.
