Yes — as long as your spine is wide enough. We recommend spine text only if the spine is at least 0.125" wide. If you're unsure, check your calculated spine width on the product page or contact us for guidance.
Common things to print on the spine:
Your book title
Author or brand name
Volume or issue number
Year or date
Make sure your text is centered within the spine area and use a font size large enough to be legible once printed. If the spine is too narrow, skip printing on it to avoid misalignment or cutoff.
