Remove spine lettering below KDP's 80-page threshold. Above the threshold, keep the text centered with the required clear space on both sides. Download a new retailer template after the interior is final. Compare the PDF page dimensions, bleed, folds, safe areas, barcode zone, and spine text against that template before upload.
