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.
Claims16
A method for recording information regarding an original image on a data carrier (10), comprising;
- (a) recording on the data carrier a recorded image corresponding to the original image;
- and
- (b) recording on the data carrier in the form of a line drawing the features relevant to identification that are obtained by spatial analysis from said original image and wherein said special analysis is applied to one or more colour separations of the original image.
A method for recording information on a data carrier (10), comprising:
- (a) recording on the data carrier a recorded image corresponding to the original image;
- and
- (b) recording on the data carrier visually perceivable features relevant to identification that are obtained from said original image;
- (c) said recorded image being applied to an image-carrying area (14, 13′) of said data carrier suitable for the application of information, said data carrier (10) having a substrate (11), said features relevant to identification being written on the substrate (11) with the aid of radiation;
- (d) the radiation used for recording said features relevant to identification not only causing blackening of the substrate but also altering the previously applied image in a controlled manner, by evaporation or combustion, thereby to visually emphasize the features relevant to identification.
