Hello again, in the meantime I found out, that you can force LyX to replace Type 3 fonts by Type 1 fonts (vector, PS-fonts). I also found out, that there's an option for creating PS with 'dvips -Pczm -Pamz', which shall replace the fonts. Unfortunately this doesn't seem to work (maybe because of Darwin - heard this one from a Linux user). Is there a way to configure Latex or pdflatex, that it replaces the fonts automatically (as a standard) ? I need readable PDFs on the screen, too, so that's why I'm asking. Thanks for any help.
Oliver
