Crease and 3^rd Level Ridge Details Workshop
(from 2 hours to 3 days)

Natural patterns are unique, including the crease and ridge texture patterns on friction skin. By examining the sequences and configurations of all types of details in impressions of the features of friction skin, the source of a questioned impression can be determined if sufficient quality and quantity of details are present in both the questioned and known images. This workshop will include a discussion of unique natural patterns, the examination process, and then conducting practical exercises emphasizing friction skin crease and third level ridge details in impressions.
