I am generating pdf using wkhtmltopdf. The text/image quality rendered in the document is not to the expected quality. Images look blurred and text does look sharp. Is there any way I can do to increase the quality?
Try giving this thread a read http://code.google.com/p/wkhtmltopdf/issues/detail?id=379
Especially the part in comment #15 about disabling smart resizing applies.
Add the command line option --disable-smart-shrinking
.
