This note demonstrates that the micro-Raman technique is suitable for examining the chronologi-cal sequence of the printing and signing imprints on the documents even if there is no intersection. This method does not cause damage or impairment to the document nor does it require sample preparation. It is objective and easy to interpret. Application of this method makes the investigation of questioned documents easier and more reliable for forensic experts in criminal cases.
