When editing your Premium Hardcover Book, you'll see a pink border around each page. When you hover your mouse over the border, you'll see the message "Items in the shaded area may be cut off".

We've added a bleed zone area to guide you in designing your pages. You're welcome to add photos or text to the edges of the page, but please note that anything in the shaded area may get cut off in production or fall into the bookbinding.

If you do have text placed within the bleed zone, you'll receive a warning before adding your project to your cart:

The bleed zone will always be present in edit mode. This border will not be printed in your book. You can view all of your pages without the border in preview mode after exiting edit mode. To exit edit mode, click the 'Done' button at the top of the editor.

This can happen if your text box runs into the bleed zone. You can adjust the text box so it no longer touches the border, but as long as your text isn't visibly within the bleed zone, you don't have to worry about it getting cut off.
