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?
I would usually use Briss or PDf Scissors before, only to roughly crop pdf margins & cut pages in two and then use k2pdfopt in landscape mode.
If needed, I would then do quick OCR-ing in Acrobat or ABBYY FineReader.
