There is no doubt that this software (Jellby's + Prince) allows to produce seamlessly from a source EPUB, PDF files of an excellent quality. I know it because, with a lot of Jellby's help, I
succeeded.
Beyond the limits?
There is a human tendency to always try to push the limits a little further. Now that I enjoy justified and hyphenated text, I think about "
optically justified text". Would this be possible using Prince? What also about inserting thin spaces? This can be done using emulation. Is there a nicer way to do it using Prince?
