Printing materials and technologies in the 15th-17th century book production: An undervalued research field

We present here the results of the imaging analysis of the entire corpus and the X-ray fluorescence (XRF) investigation performed, focusing on the XRF data and their statistical treatment using a combination of Principal Component Analysis (PCA) and Logistic Regression. Thanks to the broad XRF investigation - more than 200 data points - and to the multidisciplinary approach, we were able to discriminate the provenances of the paper - in particular for the German and Venetian volumes - and we potentially identified a chemical fingerprint of Venetian papers.
