I think the problem is, rather, that the authors used a TeX setup in 
which the CM fonts are not available in PostScript format. Hence the 
fonts are created by TeX at runtime, from the original MF (MetaFont) 
sources, in bitmap PK format (generally at 300 or 600 dpi), and dvips 
includes these bitmap fonts in the PS file that it produces, in the 
form of PostScript Type 3 fonts.

Hence the jagged output. On my setup the PDF file (created from the PS 
file using either TeXShop, Preview or Distiller) looks slightly better 
in Adobe Reader than Preview.

You can see the difference between the two types of fonts by looking at 
the title, abstract and table of contents, which are in the (vectorial) 
PostScript Type 1 Optima font, and the rest of the paper, which is in 
(bitmap) PostScript Type 3 fonts called T1, T2, etc. (actually CM
