Abstract:
T ak ing advantage o fConfoca lM icro-Ram an techno logy, seve ra l comm ercial inkpads, stam p-pad ink and prin-t ing ink are stud ied by the IR ( 785 nm ) laser. The results show that inkpads and stam p-pad ink have the 1 235 cm - 1 characteristic peak on theRaman spectra because o f conta ining the ester, wh ile prin ting ink has 1 086 cm- 1 charac teristic peak because of conta in ing the a lcoho lm ater ia.l This d iffe rence can be used to identify the counterfe it cop ies reco rded w ith printing ink from those recorded w ith inkpads and the stamp-pad ink. Furthermo re, different brands inkpads, stamp-pad ink and pr inting ink have the d iffe rent characteristic peaks on the Ram an spec tra, so the brands of ink and the copies can be d istingu ished eas ily. Confoca lM icro-Ram an techno logy prov ide a sc ientific m ethod to judge the ev idence o f ink m arks in the area of jud ic ia l au thentication.
