Fingerprinting of Questioned Documents

Non Destructive Handwriting Analysis Before Fingerprinting

Although DDL does not perform fingerprint detection and/or examinations, there are occasions where fingerprinting a document is required. In the process of fingerprinting paper dyes, chemical developers and treatments used in the procedures can affect and even destroy potential handwriting evidence. Therefore, when considering fingerprinting a document, the original document must be first submitted to the handwriting section of the laboratory protected by a plastic sleeve or package. The document(s) will be processed for handwriting evidence without disturbing any latent fingerprints and returned in its’ original condition.
