In case you were wondering about the scientific differences between Hero and Ostrich inks observable through scanning electron microscopy.

For example, some especially important signatures on a contract which were suspected of having been altered without the knowledge of one of the parties cause legal dispute. Therefore, determining which of the ink lines was made last [11,12] may help in solving the dispute as a recurrent matter in many police investigations and in courts.

 

Just from the opening paragraph -- "which of the ink lines" -- I suspect the forensics is focused on Chinese logographs, in which one could possibly add a stroke or two and completely change a "signature" (or maybe draw the figure in a different stroke order than normal -- whereas occidental signatures tend to be left-to-right, no actual variation in stroke order or additions)

 

Still need to read the full article (surprised that the full article was available as a PDF).
