Cover text sits too close to the trim
Live content on a cover must stay 0.375" inside the trim edge — a different, larger figure than an interior's outside margin.
What to do
- Covers are cut with a tolerance, so anything within 0.375" of the trim can be shaved off. Background art should run past the trim into the bleed; text and logos must not approach it.
- The spine is the tightest case: on a narrow spine the safe band is a few points wide, and title text either shrinks or has to be dropped.
- The cover builder draws the safety rectangle over your artwork, and the calculator's diagram shows it against the full artboard.
