Why are the fonts in Document Viewer so ugly and non-antialiased?
-
could you perhaps give a link to a sample file? The fonts look fine in my pdfs.– adempewolffAug 22, 2012 at 7:20

My guess is that you see this behavior only for some documents, right?
In that case I think that you see output from an old LaTeX version with standard LaTeX bitmap fonts. I have found the document that you are showing and the fonts are non-aliased also on my system -- although I know that regular documents look perfect. It's also non-aliased under Windows, so there.

1Oh, so I can't help it seems. Well, we'll live through it - with a cold beer in hand the fonts doesn't really matter. Aug 22, 2012 at 7:50

There is no text in your pdf file, but a compressed jpeg image for each page.
So the font cannot scale. It is a fixed picture, not a scalable font.

2Nah, there is text alright: www-robotics.usc.edu/~stergios/icra99-3D-final.pdf. It's just that it doesn't use vector fonts.– JanuaryAug 22, 2012 at 7:36

1The main font is of poor Quality... it is a type 3 font. Type 3 Fonts are bitmap fonts -> same problem like with other "pictures" they are not scalable. Aug 22, 2012 at 7:45

1@mondjunge: Type 3 fonts are not of poor quality. They are simply not optimized for low resolution devices like screens. Aug 23, 2012 at 6:50

What Martin said. Your answer is incorrect in that there is no "compressed image for each page", JPEG or otherwise.– ishAug 23, 2012 at 7:11

You are correct, the first time I downloaded the pdf it was copy protected, so I could not highlight any chars, so I thought it was a jpeg... Aug 23, 2012 at 13:11
