Elliptical
This dot shape is used to avoid the sharp transition at 50 percent that
is characteristic of the Euclidean dot shape. This is an excellent dot
shape for general use. However, it is not suitable for printing flesh
tones, as the chaining of the Elliptical dots at 40 percent and 60
percent may cause visible streaking in the skin tones under certain
printing conditions.

Round
This is a commonly used dot shape that gives a smooth appearance in
highlights and midtones. It is commonly used in imaging flesh tones
and images with high and medium key detail. Dot gain and tonal jumps
can be a problem in the shadow areas, because the white space at the
center of four adjoining circles can easily become filled with additional
ink as the dots grow and begin touching. However, with accurate and
stable imaging, shadow detail is preserved remarkably well on press.
