Abstract
The invention relates to a method for recording image information on a data carrier which has a substrate that can have optically identifiable information written to it by the application of radiation, and an image-carrying area suitable for the application of information, in which the whole image information of an image to be recorded is applied to the image-carrying area. In order to increase the tamperproofness of the image to be recorded and the identifiability of the said image, without adversely affecting the brilliance and colour fidelity of the image, the invention provides for a portion of the image information that is to be recorded to be additionally written to the substrate with the aid of radiation.
