Why do dotted strokes exported via indesign look so terrible in adobe reader / acrobat?
Redacted screencapture for proof:

your strokes with either dotted or japanese dots applied look, quite frankly, horrific.
i would use the term 'bitmapping' but the output does not approximate pixellation. the vectors are just not antialiasing / smoothed.
cannot locate any setting in export or other to ameliorate the appearance of these
kindly advise
