Page cut offs

We have a great page on creating using Aperture. Check it out here https://www.prestophoto.com/help/Apple+Photo+Book+Printing

Are my pages in the safe zone for cropping? I made the book in Aperture and always leave a ten space margin all around the outside of the page and twenty spaces in the binding part of the book. This is my first order and am trying to learn all the nueances.
