The elements of a book cover
A book cover is more than just the front page of the outside of a book. When we talk about a book cover, we mean the back cover, the spine and the front cover connected as a spread. A print-ready book cover also needs to be a PDF with at least a 3 mm bleed and crop marks. Read on to learn how to create a print-ready book cover!
What a print-ready book cover looks like
The front and back covers will be the same height and width of the interior layout. The spine will need to be calculated (https://printondemand-worldwide.com/resources/spine-width-calculator-and-book-sizes-explained/) according to the final page count, paper gsm and type of book. The typical gsm we use for a paperback book interior is 80 gsm, bond.
The bleed is there to ensure that if there is any error when printing or cutting the cover, there will not be a white border. The cover image/ colour of the cover needs to extent over to the bleed.
Below you can see a diagram showing the back cover, spine, front cover, bleed, and crop marks.
How to export a print-ready PDF cover file
with Adobe InDesign
First you need to set up the document so that the back cover, spine, and front cover are each its own page, not one long page. Then, remove the margins from the spine page and adjust the width to the calculated spine width. Note that you must always confirm spine width with the printer once you go to print. Select all the pages in your pages tool and right click to deselect ‘Allow document pages to shuffle’. You can then simply drag the spine page between the back and front covers.
Once you have done this and designed the cover, ensure you have the following elements:
- The ISBN – on back cover
- Barcode – on back cover
- Book title – on front cover and spine
- The blurb – on back cover
- Author’s name – on front cover and spine.
Go to file and select ‘Export’. Ensure that by page options you have selected ‘All’ and that ‘Spreads’ is selected.
Move down to ‘Marks and Bleeds’ on the left panel and ensure you have selected ‘Crop Marks’, ‘Bleed Marks’ and selected to use document bleed settings or include 3mm manually. Then select ‘Export’.
You will now have a fully functional print-ready PDF. Armed with this new knowledge, you will now be able to provide a publisher or a printer with a usable cover PDF document. That is how you create a print-ready book cover.
