To find out more about the provenance and authenticity of prints by Rembrandt, scholars are carrying out research into paper that was produced in the seventeenth century. A particular method has been used in this research since a number of years, namely Computational Art History: computer assisted image analysis.
Prof. Rick Jonson uses Rembrandt's work to explain the workings of such a computer system which he developed. This system is able to identify watermarks and chain line patterns in paper. These characteristics are linked to the manual production of paper in the seventeenth century, which involved the use of paper moulds. By identifying which prints and drawings were made on the same moulds, specialists are able to date the works. This used to be done by visual analysis, though this was a time-consuming process. Nowadays computers are able to assist in this process.
