FORENSIC SOLUTIONS / DOCUMENT EXAMINATION
Look beyond the surface of a document.
Connect file history, signature regions and physical security features in a document examination workflow. Start with the original file or a purpose-made photograph, then select the tools that fit the evidence.
01 / EXAMINATION CAPABILITIES
Ask a better question.
See more of the evidence.
What does the file, page or capture reveal about a questioned document?
Document history
Read embedded metadata and check timestamp or software inconsistencies in supported original files.
Explore document historySignature extraction
Locate signature-shaped regions, create cleaned crops and preserve their link to the document page.
Explore signature extractionPhysical feature enhancement
Reveal indentation shadows, transmitted-light watermarks and eligible colour-laser printer identification marks.

A practical route
through the evidence.
Extracted metadata, linked signature crops and enhanced physical features.
- 01
Choose the right capture
Use an original digital file for embedded metadata. For physical features, prepare raking-light or transmitted-light photographs instead of a general scan.
- 02
Inspect targeted features
Extract linked signature regions, inspect timestamps and editing traces, or reveal indentation and watermark signals from suitable captures.
- 03
Connect page and finding
Keep crops linked to their page and carry metadata, enhanced copies and selected examination outputs into the evidence record.
Original JPEG, TIFF or PDF for metadata; document page images for extraction; dedicated lighting for physical features.
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
Metadata can be absent or edited. Indentation needs raking light; watermark enhancement needs transmitted light. Printer-source decoding needs an eligible colour-laser print and a scan of at least 300 dpi. This workflow does not date paper or ink.
Can the platform date paper or ink?
No paper-age or ink-age analysis is described for this platform. The document workflows cover embedded metadata, extraction, suitable feature enhancement and eligible printer marks.
Which files support metadata examination?
The metadata workflow reads JPEG, TIFF and PDF. PNG is not accepted by that workflow. Signature extraction and other document workflows have separate format requirements.
Will an ordinary scan show indentations or watermarks?
The enhancement methods need a physical signal captured with the right lighting. Use raking light for indentation shadows and transmitted light for a watermark; a flatbed scan usually does not contain those signals.
