However, only one value is used to classify it in the henry classification line. The fraction thus obtained is the primary classification of fingerprint. Secondary classification=U/U, subsecondary= UUU/UUU; and other classification values governed by respective ridge counts. placed immediately to the left of the primary classification column.
