FORENSIC SOLUTIONS / SIGNATURES & HANDWRITING
Turn a disputed signature into a structured comparison.
Bring questioned signatures, independent references and handwriting evidence into one connected examination. Compare visible characteristics, quantify writing features and keep every output linked to its source.
01 / EXAMINATION CAPABILITIES
Ask a better question.
See more of the evidence.
Does the questioned writing share characteristics with the known references?
Multi-reference comparison
Compare a questioned signature with a set of known signatures rather than relying on a single pairing.
Explore multi-reference comparisonWriting features & authorship
Measure baseline, slant, spacing and stroke width, or compare questioned and known handwriting for common authorship.
Explore writing features & authorshipReal movement & pressure
Explore writing speed, timing, pen lifts and pressure when genuine digitizer captures are available.
Explore real movement & pressure02 / FROM SOURCE TO OUTPUT
A practical route
through the evidence.
A documented comparison of shape, stroke structure and writing features.
- 01
Prepare the comparison
Extract signature candidates from a document or start with an image. Keep questioned material separate from independently sourced known samples.
- 02
Compare more than one signal
Use multiple reference signatures, visual comparison and handwriting measurements to examine agreement and differences across the evidence.
- 03
Build the evidence record
Bring comparison outputs, reference information and linked crops into the reporting workflow, with the source and selected method retained.
Questioned signature or handwriting, plus suitable known references. Use genuine digitizer captures for timing and pressure.
03 / A MORE CONNECTED PROCESS
Less fragmented work.
More visible context.
Bring repeatable processing and measured comparisons into the workflow. Time and cost depend on the source material, selected methods and reporting scope.
| The task | Manual workflow | With Admissible Lab |
|---|---|---|
| Prepare material | Organise files and prepare each comparison separately. | Use defined input requirements and linked source material. |
| Inspect relevant features | Locate features and record observations individually. | Combine targeted processing with quantified or mapped outputs. |
| Connect the record | Collect notes and derived exhibits across separate tools. | Carry selected outputs and source context into reporting. |
| Assess performance | Effort varies with the material and the examination task. | Evaluate suitability and validation for each specific method. |
04 / PRACTICAL QUESTIONS
Know what
to bring.
Technical scope
A visual similarity measurement describes resemblance; it is not an authenticity verdict. Timing and pressure require real capture data and cannot be recovered from a scanned signature.
Can I compare signatures in a PDF?
The visual-similarity workflow accepts PDF or image signatures with 1–20 references. Other comparison workflows have their own image and reference requirements; the signature module lists them separately.
What if I have several known signatures?
A multi-reference comparison helps expose natural variation. Some workflows require at least two references; combined evidence also depends on the available reference set and its agreement.
Can a scan reveal writing pressure or speed?
No. Real timing, pen-state and pressure measurements require genuine digitizer capture data. A scan supports static appearance and stroke measurements instead.
