Why does rotated text appear in the PDF at a much lower resolution than plain horizontal text?
A. The Quark programmers were too lazy to draw rotated text in a way that would work well with non-PostScript printers. You can get somewhat better results by increasing the “Maximum Resolution” setting in the “Misc.” panel of PrintToPDF’s preferences dialog. An alternate workaround would be to make rotated text in some application that handles rotated text better, such as PowerPoint, and paste it into Quark as a picture.
