A print-ready PDF is the production file for a book readers will hold on paper. Once the pages are set for paper, that file is a print PDF. Develop your manuscript in Bookeen, then check the print PDF against the printer’s requirements. A print-ready file is the interior a press can impose: a known page size, margins that survive trimming, and a proof that matches the file you will upload. Calling a screen export by a shorter name does not give it those properties.
Print PDF files for books contain an interior prepared for a chosen trim size, margin arrangement and bleed setting. Print PDF requirements vary by printer and print option. Amazon KDP documents these choices for paperbacks; follow the specification for your own print PDF destination. Start from the trim you mean to print, then set the live text inside a margin the printer can cut without eating a word. A print-ready file is finished only when you have looked at that trim, not when the writing felt done.
For a KDP paperback with bleed, the PDF page must extend beyond the finished trim size. KDP adds 0.125 inches at the outside edge and at both the top and bottom; a 6 × 9 inch book therefore uses 6.125 × 9.25 inch interior pages.
“increase your page size and ensure that the image extends beyond the trim line”
KDP’s interior bleed extension is 0.125 inches (3.2 mm) at the top, bottom and outside edge. This is a KDP paperback specification, not a universal printer rule.
For the 6 × 9 inch example: page width = 6 + 0.125; page height = 9 + (2 × 0.125). The extra width is on the outside edge, not the binding edge.
KDP specifies minimum top, bottom and outside margins of 0.25 inches without bleed or 0.375 inches with bleed. The inside margin depends on page count.
Use the specification for the exact edition after finishing the manuscript in Bookeen. Check the complete interior and the separate cover file in the destination’s preview; the dimensions above do not replace proofing. Hold the comparison to the printer's current page, not to last year's export. Check the gutter, the margins, and a page with a figure. Approval is their review of the file you uploaded, plus the proof you were willing to look at.

When should you choose print PDF files for books?
Plan print PDF files around the physical reading task. A portable guide, reference volume and workbook may need different page dimensions. Review long headings, wide tables and answer spaces before polishing the print PDF layout. Keep the print cover and interior as distinct production tasks. Choose this path when someone will hold the book. Screen reading can tolerate a different page shape. Paper cannot. If you do not yet know the trim, you are not ready to freeze the interior, however complete the sentences are.
Choose the destination and physical book size. The trim decides the live area. Choose it before you design the interior. Changing it later moves every heading, figure, and page break you already checked.
Identify pages with images, tables or answer spaces. Pages with figures or answer spaces fail differently from plain text. Find them early and look at each one in the exported file, not only in the writing view.
Keep the cover and interior preparation tasks distinct. The cover and the interior are usually separate files because they are printed differently. Do not assume a cover belongs at the front of the interior.
Review print PDF files page by page
Read print PDF files from the first page to the last. A chapter opening can look good alone and still feel wrong after the previous page. Review contents, headings and page references together in the print PDF. Watch for blank pages and isolated final lines. Turn every page of the exported interior. Look for headings tight against the edge, figures that cross the safe area, and blank pages you did not intend. A spot check of the first chapter misses the collision on the page where a table starts.
Check chapter openings and page-number consistency. Chapter openings should fall where you intended, and the page numbers should match the contents list. A shift of one page is enough to send a reader to the wrong spread.
Inspect inside margins where the book will be bound. The inner margin has to survive binding. Text that looks centered on a loose sheet can disappear into the gutter once the book is bound. Check that edge on a proof, not only on screen.
Look for cramped tables and captions separated from images. A caption stranded on the next page, or a table squeezed until the type is unreadable, is a layout failure. Give the figure and its note the room the trim allows, or move them.
Compare the exported page dimensions with your chosen print option.
Proof print PDF for books
Proof print PDF files for books before distribution. Your Bookeen manuscript is the starting point; the print PDF needs the destination’s preview or proof process. Examine a physical proof when appropriate and record corrections so later print PDF versions do not reintroduce layout problems. Order a proof or print a signature yourself and read it as an object, not as a file. Mark trim, page order, and any line that fell into the gutter. The proof is allowed to send you back to the manuscript. That is what it is for.
Review the complete export before upload.
Use the printer’s checks for the actual production settings.
Inspect a proof for readability and layout issues.
Save the approved manuscript and print file as a matched version.
Print PDF for Amazon KDP
Prepare print PDF files for the physical edition and review digital editions separately. Start from the trim you mean to print, then set the live text inside a margin the printer can cut without eating a word. A file that looked fine on your desk can still be the wrong size for their press.
Amazon KDP paperback interiors
Amazon KDP requires PDF manuscripts when paperback pages include bleed. Check trim size, margins, embedded fonts and the separate cover requirements before submitting your print PDF. Review the proof with the actual print settings. Use their current interior template for the trim you chose, then preview the page they show you. Gutter, margin, and page count are the usual failures. A file that printed nicely at home can still be the wrong size for their press.
A print PDF layout answers a paper-reading task. For a digital edition, review the EPUB guide and the delivery requirements for Kindle or Apple Books instead of assuming the print interior suits every reading experience. A paper interior is not the file for a phone or a dedicated reader. Build those editions from the same settled manuscript, with their own review. Do not upload the press file and expect it to read well as flowing text.
No. A print-ready PDF may still use different page dimensions from the paperback interior the printer expects. Treat print preparation as a separate review. Follow your printer’s current specification and inspect the file you actually submit. The file still has to match the page size and margins the printer published, and you still have to look at it. A tidy export can be the wrong trim. Read their current specification and inspect the file you will actually send.
What is trim size?
Trim size is the finished book’s width and height. It affects how much material fits on a page and how the book feels in the reader’s hands. Confirm the available options with your printer before settling on the interior layout. Trim is the size of the finished page after the printer cuts the sheet. Your text has to sit inside that size with a margin, or the cut will take the ends of lines. Look up the trim your printer offers before you lock the layout.
Is the cover included in the interior PDF?
Keep track of your destination’s cover and interior requirements separately. A book cover and its interior serve different production purposes. Do not combine files simply because they belong to the same book; follow the upload structure your printer requests. Usually the interior and the cover are separate files, because they are printed differently. Confirm that with the printer. Do not assume a cover spread belongs at the front of the interior, or that the interior's first page is the cover.
Does a print PDF export guarantee printer approval?
No. Review the export against the destination’s requirements and complete its checks. The book’s content, rights and production decisions still need your attention. File generation is one step toward publication, not a substitute for proofing. An export can be well made and still fail a rule you did not check, or a rule the printer changed. Approval comes from their review of the file you uploaded, plus the proof you were willing to look at.
