Review transparent and layered artwork in the editable source, apply the production treatment required by current KDP guidance, and inspect the exported result. Flattening can change appearance or editability, so preserve the source and verify text, edges, and overlaps in the final file rather than assuming the operation succeeded visually.
Identify where transparency is used
Inspect the manuscript and cover for translucent shapes, shadows, overlapping images, and other effects that depend on transparency. Include imported artwork, because an apparently simple image may contain layers or effects not visible in the page view. Record the assets that need production attention.
Distinguish the intended visual effect from the underlying file structure. A pale box may be a solid light color or a transparent shape over another object. Those designs can look similar while requiring different inspection during export, so review the actual source properties where possible.
Preserve an editable production source
Keep a version with editable text, layers, and linked assets before applying a flattening step. Record the version used for the print export so later corrections can return to the appropriate source. A flattened result should not become the only surviving form of artwork that the book still needs to revise.
Organize the source and output clearly. Name the files according to their role and keep obsolete exports outside the active release set. This reduces the chance that a designer edits a flattened file unnecessarily or that an older unprepared version is selected for submission.
Check the current requirement and workflow
KDP's paperback submission guidance instructs publishers to flatten transparent objects and layers in the native file before publishing. Review the current guidance and determine how the chosen production application performs that operation. Do not assume that a generic print preset establishes every required property.
Use the application documentation when the effect of a setting is unclear. Different export routes can treat artwork differently, and the relevant question is what happened in the resulting file. Preserve the selected settings in the production record rather than relying on a remembered sequence of clicks.
Inspect overlaps and text after flattening
Compare the exported artwork with the approved source appearance. Check areas where objects overlap, where shadows meet backgrounds, and where text sits over a shape or image. Look for changed edges, unexpected blocks, altered contrast, or missing details that affect readability.
Read small labels and cover text at the intended size. A visually similar export can still make lettering less clear or change the boundary between a label and its background. Do not judge the result only from a zoomed-out page thumbnail, where these changes can be easy to miss.
Review the complete page rather than isolated assets
Place the prepared artwork in the final layout and inspect its interaction with surrounding text and backgrounds. An asset that looks correct alone may reveal a mismatch when placed over a different page color or next to another illustration. Check the actual context the reader will see.
Verify that late edits did not reintroduce an unprepared object. Adding a new caption box or replacing one image after flattening can change the file's production state. Treat those changes as a reason to repeat the relevant checks instead of assuming the earlier preparation covers the new content.
Close the check against the selected export
Record the source version, production treatment, and inspected output. Compare the file selected for submission with that record so the review does not accidentally apply to a different export. Preserve any unresolved finding and correct it before treating the package as ready.
Use the appropriate preview and physical review available for the intended edition to examine the finished appearance. These checks complement the file preparation rather than replacing it. Keep the editable source and the verified export together so a later correction can be made deliberately without recreating the artwork from a flattened image.
Frequently asked questions
Clear answers for this publishing decision.
Does a pale background automatically mean transparency is present?
No. It may use a solid light color. Inspect the source structure and effects rather than inferring the file treatment from appearance alone.
Should I discard layered source files after preparing the print export?
Keep the editable sources with clear version records. They support later corrections and help distinguish the production output from the material used to create it.
Does flattening guarantee that the exported page looks correct?
No. Compare overlaps, text, edges, and contrast with the approved source, then inspect the artwork in the final page context. The operation still needs visual verification.
How do I get from an idea and a brief to an editable manuscript I can finish?
Write the brief first, generate a structure you can edit, then draft and revise the manuscript in reviewable sections so one change never overwrites work you already approved.
