This bug has been opened here: http://bugzilla.ubuntu.com/show_bug.cgi?id=14070 "I have got lots of technical documents/datasheets in PDF format, ... Also, the quality of the rendering is poor : I often can't even read the small characters in diagrams. ... http://bugzilla.ubuntu.com/attachment.cgi?id=3359 sample datasheet ... > can you make a screenshot of the issue on the example pdf you put with this bug? ... http://bugzilla.ubuntu.com/attachment.cgi?id=3395 Evince next to Kpdf I just made one. It's page 10 of the document. Evince is on top, and Kpdf at the bottom. I adjusted the page width so that the zoom factor in both apps is exactly the same, as this obviously affect anti-aliasing/rendering. The interesting part is the small characters in the diagram on the right part of the page. Evince at first might appear cleared to you, because the line look "thiner". However there are many missing pixels, that make it hard to read, and force me to "guess" what's writen. Data sheets are there to provide reference information, "guessing" is not good at all, you must sure of what you are reading. Now with Kpdf, it's the other way around : it may appear more "blurry" to you a t first (I think obvjectively it is, in some places), but the advantage is that there is no mising pixels, and that ALL the text inthe diagram is actually readable without effort, whereas with Evince some characters may be clear, but many aren't. Kpdf is more "consistent", the text will always be complete and readable."

This is likely due to cairo's poor downscaling quality.
