We presented a proof of principle of the feasibility and possibilities offered by the application of an inspection method that can be widely exploited in the forensic field.
A possible perspective of our study could concern an enhanced number of considered thermal papers and donors. By increasing the examined sample, it will be possible to provide even a
significant statistical result concerning the probability of successfulness for the application of the proposed method.
To conclude, the presented method allows to extend the capabilities of the forensic laboratories, it is non-invasive and can be easily performed with experimental apparatus widely diffused in the scientific investigation.
