Every book jacket must accentuate the core message to succeed in its mission of selling the book it covers. Designers aim for this by incorporating typefaces, imagery, and the perfect color palette to make a book appeal to its intended market.
One bump that comes along the way, however, is changes and requests regarding this work. While feedback is important and helpful for a designer, those based on personal likes and interests may diminish the appeal the designer worked to create.
Wondering what specific requests start the downward turn? Keep this list of common “to be avoided” design requests handy to ensure professionalism and marketability is maintained (along with your designer’s sanity).
