The detection of these tags is complicated and requires expensive and rare scientific equipment.The primary method of detection of these tags is called XREOF (X-ray excited optical fluorescence).Information on these tags is confidential and closely kept.The procedure most commonly used for the detection, isolation, and analysis of these date tags in ink dating is: The comparison between the known tag and the questioned ink being examined should focus on whether the florescent compounds are the same color in the known and questioned.No more than three of the four tags were ever used in a given year.
