Résumé

The Print-and-Scan (P&S) process is generally considered as being a random process that can be modeled by a white additive normal process, ergodic in the wide sense. This study aims at experimentally validate or invalidate this hypothesis. Moreover, the experiments we carried on have been conducted in order to separate the printing from scanning impact. The main conclusion of these experiments is that the usual hypothesis cannot be supported by the experiments. The normal modeling can be invalidated for the whole P&S process. Moreover, it has been highlighted that this process cannot be considered as being neither white nor ergodic in the wide sense. The scanner noise seems to be mean ergodic and closer to a Laplace, than to a normal distribution.
