Ink Library Uses
The ink library is not a tool used to scrutinize anonymous letters deemed as potential threats to the president. There have been both severe and minor situations in which the counterfeit truth was revealed using the library. There are instances where falsified accounting documents were identified. Even a fake baseball signature can be and was captured in the past. This is achieved using a three-stage identification process that can identify just about any ink on any document that could ever be produced.
Plans for the Library
One of the reasons that the ink library is so effective is the fact that many letters are still written by hand today. However, the world is quickly moving into an all-digital future, and the library needs to adapt as best as possible to remain a feasible tool. To this end, there are plans to make the library a digital tool as well to preserve its relevance and effectiveness. There is no concrete data on how the Secret Service and FBI plan to achieve this feat.
