Marks
Sub-specialties: Tyres, Tools, Footwear, Packaging &
manufacturing, Feature comparison
The specialty of marks covers a very wide area
and encompasses many forms of examination. It includes a range of
well-established evidence types including the comparison of marks
made by footwear, tyres and tools.
The objective is to reach a view on whether or not a particular
item was responsible for a specific mark. The examiner is concerned
with visualisation, assessment and comparison of detail to
interpret the findings.
Another area covered by this specialty is the examination of
packaging and other manufactured items to determine the degree of
association between items and to assess whether or not they were
from the same original source. This includes examinations of
extruded material such as plastic bags and film as well as items
that are manufactured by other processes. The examiner studies
various macroscopic and microscopic features to formulate an
opinion.
