Non-contact analysis of drawings,
documents and archival materials


book2net has developed a new method for multispectral analysis of documents and drawings. Individual or series of scans can be carried out at definable nm intervals. The scan results can be overlayed and analyzed with pixel accuracy. The book2net process works without changing filters (i.e. vibration-free) and without post-correction of sharpness and focus in the spectral ranges (i.e. pixel-accurate to scale).

The book2net multispectral system is an innovative, non-invasive tool for scientific and material-technological analyses, for forensics and for the comprehensive documentation of works of art, creation processes, authenticity or condition.
With the help of our system, up to 11 images in a wide range of wavelengths and their combinations can be generated within a few seconds in fully automated processes, depending on the model.

The system allows the visualization of faded inks, underdrawings, combinations of materials used in writing, drawings or paintings, as well as the detection of traces of organic aging processes. This enables the verification of originals for their material completeness as well as detailed authenticity analyses.
