Check full-bleed images on both left and right pages of the intended paperback. Confirm that the exported page dimensions follow the selected bleed setup, that artwork reaches the required outer edges, and that meaningful details remain safely positioned. A correct-looking right page does not establish that its left-page counterpart uses the appropriate geometry.
Confirm which pages require bleed
Identify artwork intended to continue to a trimmed page edge. Distinguish it from an image deliberately surrounded by white space. The production setup must reflect the actual design, and the image placement should make that intention clear before the final file is exported.
Record the accepted trim size and the current KDP bleed requirements used for the edition. KDP's paperback guidance distinguishes the top, bottom, and outer edges when describing interior bleed. Keep that source with the production record rather than relying on a remembered rule that every page edge is treated identically.
Inspect a left-page and right-page pair
Choose actual pages from the manuscript, including any artwork placed near a chapter boundary. Identify which side of each page faces the binding and which is the outside edge. Review the exported single pages in their reading sequence so the design is evaluated in the position it will occupy.
Do not assume the layout application's facing-page view proves the export is correct. Inspect the resulting file dimensions and image coverage as well. A page can look convincing in the editor while an export setting changes its size or excludes artwork that extended beyond the visible design area.
Separate image coverage from important content
Check that the background or image area extends as required, while faces, labels, and other essential details remain appropriately positioned. Extending a photograph to an edge does not mean every part of that photograph can be placed equally close to the cut. Decide which details the reader must retain.
For example, a landscape image may tolerate loss of a small amount of sky, while an instructional image may fail if a tool tip or label is cropped. Identify those critical details in the placement record. Review their position on each page rather than approving the asset once and assuming every crop is equivalent.
Watch for mirrored placement assumptions
A layout may mirror margins or reuse a page design to create the opposite side. Check the resulting image placement explicitly. The outside edge changes sides, but the meaning of an image does not necessarily survive a simple reflection or a different crop.
Keep the artwork's content separate from the page geometry. If a figure shows a directional action, reflecting the image to fit a mirrored layout could change the instruction. Adjust placement or composition deliberately, and revisit captions or motion indicators when the new crop changes what readers can see.
Review sequences after pagination changes
Recheck affected image pages when a section is inserted, removed, or moved. The change may alter which pages appear on the left and right, along with the surrounding reading sequence. An earlier placement approval may no longer apply to the same page's new position.
Use the final manuscript order for this review. Keep a short list of pages whose artwork depends on side, gutter relationship, or adjacent material. This makes it easier to target the check after a late edit without assuming that an unchanged image file means an unchanged reading experience.
Verify the actual submission and proof
Export the paperback interior according to the current file requirements, including the required PDF workflow for bleed content. Review the accepted file in the available preview process and inspect a physical proof for the edition's important image pages. Record any crop, edge, or binding-related findings against the specific page and file version.
Retain the production settings and accepted placements with the editable source. If the book changes trim size or artwork arrangement later, repeat the relevant left-and-right checks. The useful approval applies to the complete page construction and its position in this edition, not merely to the original image asset.
Frequently asked questions
Clear answers for this publishing decision.
Can I approve bleed by checking only the first image page?
No. Inspect representative left and right pages and any exceptional placements. Different positions or crops can expose problems that one page does not show.
Should artwork be mirrored to fit the opposite page?
Only when that is an intentional, reviewed content change. Reflecting an instructional image can reverse an action or alter meaningful details even if its placement becomes easier.
Why recheck after adding a text page?
Pagination changes can move later artwork to the opposite side or change its relationship with adjacent content. Review the affected final sequence.
Does a correct image resolution prove the bleed setup is correct?
No. Resolution, page dimensions, image coverage, and protected content placement are separate checks. Passing one does not establish the others.
Which trim size, page count, margins, and bleed setting work together for my paperback?
Check the complete combination first: a trim size, ink and paper type, and page count must be a supported KDP set, and the page count then fixes the minimum inside margin and whether the interior needs a bleed page size.
