Intriguing Facts about Handwriting Analysis

Solving the Mystery

Often the subject of mysteries and thrillers, handwriting analysis is actually a key component in many types of criminal investigations. These can run the gamut from forged checks and artwork to contested wills and signatures and more dramatic cases involving ransom notes or blackmail letters.

Common Forgeries

Signatures are the most commonly forged type of writing and require more complex analysis than regular handwriting samples. Generally, several examples of the signature, penned around the same time period, will be used for comparison with the signature in question. There are a number of ways signatures can be duplicated. They can be digitally copied by scanning, or by using cut and paste options. Forgeries can be also produced by hand, using tracing or imitation.

Forensic Analysis

Handwriting analysis in San Diego uses both visual and microscopic methods to determine the authenticity of a signature or writing sample. Different types of document authentication may require numerous types of examinations. This can be a traditional visual inspection, or it may involve high technology such as infrared or thin layer chromatography, to make a chemical analysis of the ink.

Falsified Documents

Authenticating documents such as wills or trusts requires more than just verifying a signature. Other techniques may include checking for differing types of paper or watermarks. A forensic examiner may also use ultraviolet light or a micrometer to test paper samples. An electrostatic detection device (EDD) may be employed to check for indentations on multiple layers of paper. Think of detectives in an old movie scribbling on a notepad to see what had been written on the top sheet of paper.

Authenticating Copies

Forensic analysis is also an excellent way to prove that copied documents are authentic. Methods of detection include identifying print technologies such as ink jet, laser, engraving, typewriting, and photocopies. This is valuable for discerning falsified documents, art forgeries, and counterfeiting.

Levels of Conclusion

There are 9 levels of conclusions in handwriting analysis. They are referred to as Standard Terminology for Expressing Conclusions of Forensic Document Examiners. These range from a positive Identification or Strong Probability, to the more nebulous Probable or Indications, to the more conclusive Strong Probability Did Not, and Elimination.
