KDP spine width rejectionRecalculate from the final formatted page count, selected paper, trim, and binding. Compare the exported PDF page size with KDP's newly generated template before changing the artwork.KDP spine text on a low-page-count bookRemove spine lettering below KDP's 80-page threshold. Above the threshold, keep the text centered with the required clear space on both sides.KDP cover dimensions do not match trim sizeConfirm the saved trim and complete sheet dimensions, then rebuild the PDF from the current page count instead of resizing a front cover.KDP cover missing or wrong bleedExtend the background through the 0.125-inch outside bleed and keep important words and faces inside the safe area.KDP cover barcode area problemLeave the required back-cover barcode area clear or follow KDP's barcode workflow. Do not place essential text or imagery beneath it.KDP cover blurry or low resolutionReturn to the source artwork and verify genuine pixels at the final panel size. Enlarging a small compressed image does not restore missing detail.KDP cover file too largeCheck the current KDP file limit, remove hidden or unnecessary content, and export one flattened print PDF at the exact sheet size without lowering essential image resolution.KDP cover wrong colour profileUse the color mode required by the current KDP workflow and inspect the flattened output. Profile conversion can shift dark detail and saturated colors.KDP hardcover cover errorKDP case laminate needs board allowance, hinge zones, wrap, and a hardcover-specific spine. Do not reuse a paperback sheet or a dust-jacket layout.IngramSpark spine width rejectionDownload a new official IngramSpark cover template for the exact title setup and use its spine width. Do not substitute a KDP paper formula.
