I normally create documents with LyX, and they are very nice, except when I convert ps files to pdf files. The pdf document created by ps2pdf looks very ugly. When I have a look at the fonts of the pdf document, a Type 3 font is reported. When I view other pdf documents they look OK on my RedHat 6.x systems. I am not sure if it is up to LyX, maybe it is a business of tetex. Can anyone help me with some hints? Miklos Nemeth
