In this paper it is studied how the analysis of the structure of the paper of Rembrandt's etchings can help determining the authenticity of the etchings and the dates of the prints. Digitised X-ray images of the etchings make the structure of the paper visible and reveal landmarks that originate from its production process. Methods for automatic extraction of these fcatures are developed. On the basis of these features, etchings printed on similar papers can be recognized by means of automatic matching procedures. With this questions concerning authenticity and dating can be answered. Since the aim is to construct a database of all the papers used by Dutch artists, specific attention is paid to how to make this database self-organizing and self-learning. This requires the application of advanced techniques from coinputational intelligence.
