3. Fig. 2
Representative examples of the UV/VIS absorbance spectra detected in the paper samples examined in this work. The arrows highlight the minor features between 200 and 250nm, which can be useful for the differentiation of the samples. The dotted arrow indicates the peak at 248nm, which is common to all the samples, and is therefore not useful for differentiation. The patterns have been shifted along the y-axis for clarity of representation.

4. Fig. 3
Absorption spectra gathered in different locations of the same sheet of paper of the A sample. Solid and dotted lines identify the spectra coming from the two different sides of the sheet. The patterns have been shifted along the y-axis for clarity of representation.

6. Fig. 5
Area of the peak at 272nm measured on one side of the sheets of paper vs. the area of the peak at 272nm measured on the other side of the sheets of paper for all the examined samples. Data points are designated by dots surrounded by their error box. Samples “M” and “T”, which deserved a separate discussion in the text, were explicitly labeled.

7. Fig. 6
Area of the peak at 360nm measured on one side of the sheets of paper vs. the area of the peak at 360nm measured on the other side of the sheets of paper for all the examined samples. Data points are designated by dots surrounded by their error box. Samples “M” and “T”, which deserved a separate discussion in the text, were explicitly labeled.
