I'm trying to upload a book to bookmundo with most of it black text on white paper, just a few pages with color images in between.
Being "clever" I used Libreoffice, exported the book as PDF and uploaded this PDF to bookmundo. They digest the PDF and produce their Preview, which looks perfect, but is considered 106 colored pages, so the price climbs from 13 Eur to 25 Eur, which is not an option.
They also accept docx, but trying that they insert blank pages and don't recognize some of my page breaks. However, when I upload docx, they correctly see only 6 colored pages and the price is correct.
Any idea, how I can produce correcty colored / black-whited PDFs?
Thank you.
