Study Notes

Handwriting Characteristics

Handwriting exhibits both class and individual characteristics; initial similarities evolve into unique qualities through personal development.
Consistency in spacing between words and letters is crucial for analysis.
Beginning and ending strokes of letters provide insight into a writer's style.

Line Habits and Quality

Writers may have baseline habits that indicate whether their writing is above or below the lines.
Flourishes or embellishments in the letters can signify a particular style, whether loopy or fancy.
Line quality, characterized by smoothness or shakiness, is an important factor in handwriting analysis.

Size and Consistency

Analysis includes checking the relative size (width and height) of letters or words between questioned and exemplar documents.
Diacritics, such as how the 'i's are dotted and 't's are crossed, contribute to the writing's uniqueness.
Consistency of pen pressure throughout the writing is assessed through shading.

Unusual Letter Formation and Techniques

Any backward letter formations are considered unusual and may indicate forgery attempts.
Evidence of pen lifts or separation during writing can suggest alterations or forgery.
The connection of upper and lower case letters through connecting strokes reveals the writer's flow.

Forgery Types

The most prevalent type of forgery involves creating a false signature.
Blind forgery occurs when the forger uses their own handwriting and does not attempt to mimic the original.
Simulated forgery involves intense practice of a specific signature to minimize natural hesitations and lifts.
Traced forgery is when a forger outlines a genuine signature onto another document using methods like a light box.

Erased Handwriting Detection

Handwriting that has been erased can be analyzed using oblique light for ink visibility or UV light to detect remnants.
Infrared radiation can identify carbon from pencil marks that have been erased.

Impression Analysis Techniques

Impressions left on paper can be viewed using an electrostatic detection machine, which collects dust from impressions.
Video spectral comparison is another method used to examine impressions.
Chromatography allows for the differentiation of ink or pen types used in the writing.
