In this particular case I had to do three steps: cut the page in two using -grid, remove the scan artifact margins (because on each second page the scan artifact margin was on the different side, and the text was not in exactly the same position as the previous text), and finally adapt the book to my ereader screen.

When doing multiple step conversion quality of pdf's gets lost... The text in the final version looks much worse than the original.

is there a way to avoid image quality loss? Maybe this could be done by enforcing use of lossless image format?
