Rounded borders in reports (1 reply)

Hi. I was wondering if printing ugly rounded borders on reports (like for tables) is my own issue due to inexperience or is it a well known issue of the report editor...

If I print the doc on paper it's good but the rendering on PDF is really ugly.
You can imagine that an invoce is often sent by PDF by mail....
And the quality I'm seeing now is shameful.

Square report are fine instead.

I'm using WD20.

Thanks
Stefano
