Question 1

What does the Video Spectral Comparator (VSC) primarily allow a forensic handwriting examiner to do?

Accepted Answer

Examine documents under different wavelengths of light to reveal hidden ink differences

Answer

The VSC uses multiple light sources and wavelengths to reveal ink differences, alterations, and obliterations invisible to the naked eye.

Question 2

An Electrostatic Detection Apparatus (ESDA) is most useful for detecting:

Accepted Answer

Indented writing left on pages beneath the one written on

Answer

ESDA reveals latent indented writing on paper caused by pressure from writing on overlying sheets.

Question 3

When a handwriting analyst uses a flatbed scanner to capture a questioned document, what minimum resolution (DPI) is generally recommended for forensic quality?

Accepted Answer

600 DPI

Answer

600 DPI is the standard minimum for forensic document scanning, capturing fine pen strokes and microscopic details needed for comparison.

Question 4

Which software feature is most critical when using digital comparison overlays for handwriting analysis?

Accepted Answer

Transparent layer functionality allowing superimposition of letter forms

Answer

Transparent layering allows examiners to superimpose known and questioned writing samples for direct visual comparison of letter forms and proportions.

Question 5

A questioned document examiner uses a stereomicroscope rather than a compound microscope primarily because:

Accepted Answer

It gives a three-dimensional view useful for examining pen pressure and stroke texture

Answer

The stereomicroscope provides a 3D, low-to-medium magnification view ideal for examining pen pressure grooves, stroke edges, and surface texture.
