Book jacket specifications can vary by publisher and printer. And with multiple other variables to consider, like the page count and turnover sizes, there’s a chance there may be gaps between your jacket file and the selected mockup since it’s not 100% tailored to that book’s specs.

So if you’d like to see how your jacket mech will fit before committing to a purchase, please download a test mockup below:

TIP! After testing, if your jacket file doesn’t quite fit the mockup exactly, Photoshop’s Content-Aware Fill feature is a workaround that’s most effective on designs with a solid color or minimally busy backgrounds to fill in small gaps between the jacket file and the mockup boundaries.
