When you are ready to take your book to the publisher/printer, check with them to see if they can print your file as you have it or if they need it converted to PDF. PDF is the best file format to bring your book to the publisher. (PDF stands for Portable Document Format.) It will make your pages perfectly stable so that the pages look the same on the printed page as what is on your computer screen. With some programs, when you move the files from computer to computer, the text and pictures can move from page to page, but with a PDF nothing moves or changes. Another problem that you can face is that the publisher doesn’t have the same program that you have or they have a different version. You also won’t have to worry about using only fonts that the publisher has, PDF will print them without having the font installed. There are free PDF converter programs online that you can download so you don’t need to buy the Adobe Professional version (i.e.: PrimoPDF). Now you have one less thing to worry about.
