Abstract
An identification card having photographically recorded individualizing data is provided. The photographically recorded data are interspersed with a security pattern in transparent ink. This pattern is printed onto the photographic layer before the photographic data are recorded. The photographic recording process is carried out in such a way that there is no darkening under the security pattern. The security pattern, recognizable through the transparent printing ink, is thus also impressed upon the photographically recorded data.
