The PDF that is generated by IEEE PDF eXpress or my own conversion utility looks terrible when I display it on the screen (see example). Why is this?
Older distributions of LaTeX and other programs use fonts that do not appear well ON SCREEN when interpreted by Adobe Acrobat. This is a longstanding issue with LaTeX that has been mostly remedied in newer releases. However, there is no need to worry, as these files print out just fine (go ahead, try it).
