To export a print-ready book interior PDF from InDesign, first get the receiving printer’s written file specifications, run Preflight on the layout, export with Adobe PDF (Print), and inspect the resulting PDF as a separate file. The correct preset, color conversion, bleed, marks, and page format depend on the job. A preset that works for one provider can be wrong for another.
1. Get the printer’s file requirements before opening Export
Ask the printer for its current interior-PDF specification or template. Record the finished trim size, whether it accepts single pages or requires spreads, any PDF/X requirement, bleed amount, color profile or conversion preference, and whether crop marks should be included. Confirm whether the cover is a separate file; do not place a wraparound cover inside the interior PDF unless the printer specifically instructs you to do so.
Also ask how the file should handle blank pages, page numbering, and the front matter. If the printer supplies a preset or job-options file, use the supplied one. Adobe’s export dialog exposes many settings, but its availability does not make any one combination a universal book-printing standard.
2. Fix the InDesign document before export
Save a versioned copy of the final layout, then open Window > Output > Preflight (or use the Preflight panel available in your workspace). Choose the profile required by the printer if one was supplied. Resolve errors such as missing links, missing fonts, overset text, and unintended page-size differences. Review warnings individually: some are acceptable for a particular design, but do not dismiss them without understanding the effect.
Open the Links panel and update any modified links. Check the Pages panel for missing, duplicated, or accidentally moved pages. For a multi-document InDesign Book, synchronize the documents and confirm chapter order and section numbering before exporting the book file.
3. Export interior pages in the format the printer expects
Choose File > Export, select Adobe PDF (Print), and use a clear filename such as Title_Interior_v05.pdf. In the General section, choose the required page range. For ordinary book interiors, export reader pages in sequence as single pages unless the printer explicitly asks for spreads. Do not impose signatures or rearrange page order yourself; the print provider usually handles imposition.
If the work is assembled in the InDesign Book panel, select the book workflow and export the included documents in the intended sequence. Before exporting, verify that every chapter file is included and that front matter, chapter starts, and intentional blank pages remain in the correct order.
4. Set bleed, marks, and color from the job specification
Use the Marks and Bleeds controls only as requested. If artwork reaches the trimmed edge, confirm that the document has the required bleed and that the artwork extends through it. A page with a white margin usually does not need bleed just because the printer offers a bleed setting. Printer marks can enlarge the PDF page box, so leave them off when the provider requests a clean trim-size page without marks.
In the Output section, follow the provider’s profile and color-conversion instructions. Do not automatically convert every image to CMYK or choose a PDF/X preset without checking what the printer accepts. Transparency handling, image downsampling, and font embedding also depend on the preset and the receiving workflow.
5. Export a multi-file InDesign Book as one PDF
Open the Book panel and verify the displayed document order. Synchronize shared styles or numbering only after confirming which document is the book’s style source. Then use the panel menu’s export-to-PDF command and check the resulting page sequence. Make sure every file was saved before export; an unsaved chapter can make the PDF differ from what you see in the layout window.
If the Book panel creates separate output files instead of one combined interior, return to the book-level export command rather than merging files blindly. After combining or exporting, check that page numbering runs as intended and that section restarts are deliberate.
6. Inspect the exported PDF independently
Open the exported PDF in Acrobat or another reliable viewer. Check the page count and sequence from beginning to end, and inspect representative pages at both fit-page and actual-size zoom. Look for clipped text, missing images, altered line breaks, unexpected blank pages, and artwork that stops short of the bleed edge.
Check the PDF’s page dimensions against the requested trim size and confirm that any bleed or marks match the printer’s instructions. Search for a few words on different pages to see whether text remains selectable, and inspect document properties for font embedding where that matters to the provider. This exported-file review can catch a wrong range or a rendering problem that the source-document Preflight panel could not show.
7. Diagnose common export problems
- Pages appear as two-page spreads: recheck the export page-format option and export single pages unless spreads were explicitly requested.
- Edge artwork has a white sliver: verify document bleed and extend the artwork beyond the trim boundary before exporting again.
- A chapter or page is missing: inspect the export range and Book panel selection, then compare the PDF page count with the layout.
- Text or color looks different: compare the chosen PDF preset and Output settings with the printer’s specification; do not make a global conversion by guesswork.
- The PDF is unexpectedly large: review image compression settings while keeping the resolution and quality required for the images and print process.
Correct the InDesign source and export again rather than patching the PDF in a way that hides the cause. Keep the source package and each final PDF version separate so the approved handoff can be reproduced.
8. Use a final handoff checklist
- Printer’s current specification saved with the project.
- Correct trim size, page range, single-page/spread choice, and page order.
- Preflight reviewed; missing links, fonts, and overset text resolved or explained.
- Bleed, marks, color, and PDF preset match the printer’s instructions.
- Exported PDF opened and checked for count, sequence, size, clipped content, and intentional blanks.
- Filename and version clearly identify the approved interior file; cover file remains separate if required.
