I just bought a new Kobo Libra Colour last fall - and I use Calibre convert all my ebooks to KePub (from epub or mobi file formats) and they work fine on my Kobo Libra Colour
when I bring in PDFs (usually scanned paper pages of books) to Calibre, it then spends some time converting it - and when I try to view those ebooks on my ereader, all the pages seem smeared and are totally unreadable...
am I doing something wrong? should I not try to convert PDFs? (just import them, as is?) is there a best method they could recommend?
thanks!
