When I export a Indesign file to pdf that has lines in it with japanese dot style, the dots appear pixelated in the pdf. But only the dots on a straight line, the dots in the rounded corner (see attached screenshots) look good, as do the dots on a circle line.

When I print the file they look good. But as I need to show this document on screen as well it has to look good on screen too.

Could you please fix this?
