Summary Wrong line width when printed to PDF

Created attachment 285526 [details] all three examples Line widths are not printed correctly to PDF. I have thought that is a problem of Apples "Quartz PDFContext" but printed with Word, fine lines are printed exactly. HTML lines in Safari are not, whereas SVG lines are printed correctly. So maybe its a Safari/Webkit problem. Behaviour: lines thinner than 1px are not printed, with 1px they are printed with a width of 2px, not very nice when 2px is the result of a wanted hairline! I attached a Word, HTML and SVG PDF-example. This problem persists for years even in OS 10.11.6.

Problem is still existing in macOS 10.14.3 and Safari 12.0.3 It is really a shame! It makes my daily work ugly.
