Abstract Seal’s determination is the important part of forensic science. In order to better beat criminality, the authors brought forward a new method to study the making process of connective seal fast and nondestuctively by means of FTIR imagine System. Combining the surface scan and reflectance mode, the different part of connective seal was scaned firstly, then according to the characteristic absorption proportion of stamp-pad ink it was determined whether the connective seal was one-off made or not. The results showed that if the connective seal was one-off made, the characteristic absorption proportion was equal. This method is rapid, accurate, impersonal and nondestructive.
