CFC Document & Handwriting Analysis 4 — Questions and Answers
Question 1: A document allegedly signed in 1998 contains ink with a dye component first manufactured in 2005. What is the correct forensic conclusion?
- The document may be authentic but was re-signed later
- The document is backdated (Correct answer)
- The signature is genuine but the date is uncertain
- No conclusion can be drawn from ink chemistry alone
Correct answer: The document is backdated
If an ink component did not exist at the purported document date, the document must have been created after that date, establishing backdating.
Question 2: Which handwriting feature describes the overall size relationship between upper, middle, and lower zones of letters?
- Proportionality
- Zonal distribution (Correct answer)
- Baseline alignment
- Letter spacing index
Correct answer: Zonal distribution
Zonal distribution refers to the relative heights of the upper (ascenders), middle (core), and lower (descenders) zones in handwriting.
Question 3: What is the primary purpose of collecting 'request exemplars' (requested handwriting samples) from a suspect?
- To obtain writing made under identical stress as the questioned document
- To get handwriting with known authorship under controlled conditions (Correct answer)
- To capture disguised writing for comparison
- To compare ink from the same pen used in the crime
Correct answer: To get handwriting with known authorship under controlled conditions
Request exemplars provide authenticated handwriting of known origin under controlled conditions for scientific comparison.
Question 4: Which alteration method is most commonly detected by examining a document under ultraviolet light?
- Erasure with a rubber eraser
- Chemical eradication of ink (Correct answer)
- Insertion of typewritten text
- Substitution of a signature page
Correct answer: Chemical eradication of ink
Chemical eradication often leaves a dulled or brightened area under UV light due to destruction of the paper's optical brighteners.
Question 5: In the context of typewritten documents, what is 'type defect analysis'?
- Measuring ink density of typewritten characters
- Identifying unique imperfections in type elements to link documents to a specific machine (Correct answer)
- Analyzing the spacing between typed words
- Comparing font sizes across different documents
Correct answer: Identifying unique imperfections in type elements to link documents to a specific machine
Type defect analysis identifies unique damage or wear patterns on typewriter keys that can link a document to a specific machine.
Question 6: Which term describes handwriting that has been deliberately changed to prevent identification of the true author?
- Simulated writing
- Traced writing
- Disguised writing (Correct answer)
- Forged writing
Correct answer: Disguised writing
Disguised writing occurs when the true author intentionally alters their own natural writing habits to prevent attribution.
Question 7: A forensic examiner finds staple holes in a contract that do not align with the holes in the attached exhibits. This observation suggests:
- The documents were bound at different times (Correct answer)
- Normal variation in stapling
- The paper was recycled from another document
- The contract was printed on a different printer
Correct answer: The documents were bound at different times
Misaligned staple holes indicate the pages were assembled and disassembled at different times, suggesting possible page substitution.
