Interior Book File
The interior of your book will need to be a PDF file that is set up with the proper trim size (width and height of the book), it must have all the fonts embedded and the text or images of the book need to be placed so that the margins are correct. Ask your book printer what their requirements are for the interior file so that you can submit the file properly. Each book printer may be slightly different. Working with your book printer during the design process will make the book printing process much easier to navigate through.
