Cover rejections are the most frustrating kind — the email rarely says whether it's your spine, your color space, or your DPI. Here's every real cause, and a free checker that names yours in 30 seconds.
Check my cover — free →An IngramSpark cover is a single wraparound PDF — back cover, spine, front cover, plus bleed — that must match the dimensions Ingram computes from your trim size, page count, and paper stock. Seven failure modes account for nearly every rejection.
Ingram derives an exact wrap size from trim + spine + bleed. If your page count changed after the cover was designed — even by 10 pages — the expected spine changed and your file no longer fits.
The most common version of #1: the designer was told "about 300 pages," the final book is 342. Spine text now wraps onto the front cover, or the barcode shifts onto the spine.
Canva, Word, Google Slides, and most design tools export RGB. IngramSpark requires CMYK PDF/X-1a. The file looks perfect on screen — that's the problem; screens are RGB.
The pre-flight reads the actual pixels of each embedded image, not the file's metadata. Canva's "300 DPI" export is the classic offender — it rasterizes at ~96 DPI internally and upscales. Full explanation here →
Covers must extend 0.125" past trim on every outer edge. A file built at exact trim size has zero margin for the cutting blade — Ingram rejects rather than risk white slivers.
Ingram places its ISBN barcode in the lower-right of the back cover (about 2" × 1.2"). Text or busy artwork there triggers a rejection or an ugly white box stamped over your design.
Same rules as interiors: every font carried inside the file, and a PDF version Ingram's pipeline accepts (1.3–1.6 is safe). Designer handoffs via "Save As" from preview apps are the usual source.
Upload your cover. 11 checks including per-image DPI, computed spine width, and the barcode zone. Auto-fix what's fixable for $9. Money-back if Ingram still says no.
