Elliptical works best where flesh tones are the predominant part of the
image, due to the fact that at any one time only two sides of the dot join,
giving the impression of smoothness.
For subjects with fine detail the square dot gives the impression of a
sharper image.
There is, of course, the round dot which can offer a compromise between
square and elliptical.
What's all this about Scitex dots. This organization never produced a drum
scanner, and although at one time they produced a large expose drum there
were never many of them sold because the major three scanner manufacturers -
for whom Scitex had to provide interfaces in order to utilize their scanner
input facility - had their own expose units as part of their scanner
packages.
Are you sure you are not confusing Scitex with Hell who had a most unusual
dot shape - rather like freshly dug potatoes - and brought about by their
inability to produce 30 degree screen angles which in turn produced a most
noticeable and entirely unorthodox rosette.
