The viability and possible applications of high resolution mark replicator casting compound in document examination

Area of Science:

• Forensic Science
• Document Examination
• Trace Evidence Analysis

Background:

• Mark replicator casting compounds are standard for toolmark detail recovery.
• Their application in recording indentations on questioned documents is unexplored.

Purpose of the Study:

• To evaluate the viability of using mark replicator compound for document indentations.
• To assess substrate damage and impact on fingerprint development.

Main Methods:

• Experiments utilized Isomark High Resolution Mark Replicator on various paper substrates.
• Tested effects on paper types, potential damage, and subsequent fingerprint development.

Main Results:

• The mark replicator successfully recorded indentations on paper and card surfaces.
• Staining occurred on some substrates.
• A negative impact on subsequent fingerprint development quality was observed.

Conclusions:

• Mark replicator compounds show potential for recording document indentations.
• Substrate staining and interference with fingerprint analysis are significant drawbacks.
• Careful consideration and further research are required for forensic document applications.
