Recording medium with colored picture information, in particular a check card or identity card

摘要

A recording medium is provided with picture information in a tamper- resistant and high-resolution form. The picture information is broken down into a light/dark portion and a color portion. The light/dark portion needed for the visual impression is incorporated in the recording medium in a high-resolution form. The colored picture information is congruently superimposed on this portion so as to produce an integral ensemble. Protection from falsification is ensured by incorporating one of the portions of the picture information in the card structure in largely tamper-resistant fashion.
