[Figs. 72-101]
Figure 102 is a sketch reflecting the various types of ridges which the classifier will encounter when engaging in counting loop patterns.
[Fig. 102]
In figure 103, the lighter lines are caused by the splitting or fraying of the ridges. Sometimes ingrained dirt will cause a similar condition between the ridges. These lines are not considered ridges and should not be counted.
[Fig. 103]
In figure 104, the dot is not the delta because it is not as thick and heavy as the other ridges and might not be present if the finger were not perfectly inked and printed.
