- Red seal inks from Korea (6), Japan (1) and China (6) were studied to investigate the feasibility of microattenuated
total reflectance (ATR) FTIR spectroscopy as a tool in the forensic study of questioned
documents involving seal inks. The technique was able to differentiate red seal inks of similar colors and
different manufacturers. Blind testing has shown that micro-ATR FTIR can identify the origin of the red
seal inks with accuracy. Data gathered were converted to a database for future reference. Also, the
technique was also successful in determining the sequence of heterogeneous line intersection from a
personal seal and a ballpoint pen. The results show that micro-ATR FTIR can be a valuable nondestructive
tool for the objective analysis of questioned documents involving different red seal inks.
