The book is printed and hence maintained in two parts, the interior and the cover. Cover file contains the back cover, spine and front cover of the book. These should not be placed randomly. The file should be prepared according to our specifications before the book is submitted for publication. Remember that we do not add anything from our side to the book before printing. So the cover file should have everything that you expect to see in the printed form, including price, ISBN barcode etc. Even if you have taken our cover design services, while submitting the book you must make sure that the files are exactly how you want them printed.
