A print-ready book is not simply a manuscript saved as a PDF. It is a production package built for a specific trim size, binding, paper, ink, printer, and distribution route. The text has been editorially approved, the layout is internally consistent, the fonts and images can be reproduced, the files meet the printer’s specifications, and a physical proof has been reviewed.
That definition prevents the most expensive formatting mistake: designing the book before choosing the manufacturing specification. A 6 × 9-inch black-and-white paperback with no bleed is a different product from an 8.5 × 11-inch full-color workbook with edge-to-edge images. Page count affects gutter requirements and spine width. Paper and ink choices affect cost and image treatment. The printer’s template—not a generic “standard”—controls the final file.
Use the workflow below whether you format in Word, Reedsy Studio, Atticus, Vellum, Affinity Publisher, Adobe InDesign, or another tool. The controls and export menus differ, but the production logic is the same.
A reliable project begins with clear file roles. Do not overwrite the editable source with the exported print file.

Purpose | Typical format | Contains | Must not become |
Approval gate |
| Editable manuscript | Editorial source of truth | DOCX, ODT, or agreed source | Final text, semantic styles, notes, asset references | A printer upload | Editorial sign-off |
| Editable interior layout | Production source | INDD/IDML, AFPUB, DOCX, or formatter project | Trim, margins, styles, masters, placed assets | The only archived deliverable | Layout sign-off |
| Print interior | Manufacturing handoff | Printer-compliant PDF | Single pages in exact order, including blanks | An ebook or cover file | Digital preflight plus physical proof |
| Cover package | Editable art plus manufacturing PDF | Layered source plus printer-compliant PDF | Back, spine, front, bleed, safe text, barcode plan | A reused template after page-count change | Current template plus proof approval |
Add a version number and date to every approved handoff. A practical convention is AUTHOR_SHORTTITLE_INTERIOR_v07_2026-08-05.pdf. Keep a change log so every correction can be traced to a proof comment, and archive the exact files used for each platform upload.
Complete developmental editing, copyediting, permissions review, fact-checking, and an editorial proofread before layout. Mark the manuscript “approved for typesetting” and identify one person who can authorize later text changes.
Text changes during typesetting are sometimes necessary, but they are not free. One inserted paragraph can alter every following page, create new widows, move illustrations, change an index, and alter the cover spine. Use a correction log with page, location, old text, new text, reason, owner, and status. Avoid parallel versions circulating through email.
Create a content map before selecting layout software. Count chapters, heading levels, lists, tables, footnotes, endnotes, figures, captions, sidebars, callouts, equations, poetry, code, index entries, cross-references, blank pages, and special characters. Record which elements must stay together and which may flow.
A text-only novel can use a template-driven formatter. A cookbook with complex tables, a textbook with anchored figures, or a picture book with full-bleed spreads usually needs page-layout software and an experienced operator. Choose the tool for the hardest repeated element, not the easiest page.
Choose the printer or platform before the trim size. Record format, trim dimensions, binding, reading direction, paper, ink, bleed, page-count range, minimum margins, safe areas, spine calculation, cover template, color space, accepted PDF standard, and file-size limit.
Never transfer a margin or bleed value from another platform without checking. Even when two printers offer the same trim size, their spine formula, safe area, barcode treatment, color guidance, or automated processing can differ.
The table below reflects the public KDP and IngramSpark guidance visible on August 5, 2026. Requirements can change; recheck the destination’s live specification immediately before export and upload.

Destination |
Interior input | Bleed | Images | Fonts/color | Prohibited/common failures |
Key limits and cover |
| KDP paperback | Bleed: PDF only. No bleed: PDF, DOC, DOCX, RTF, HTML, TXT | 0.125 in top, bottom, outer; page is +0.25 in high and +0.125 in wide | Minimum 300 DPI; recommends max 600 DPI | Embed fonts/images in native file; flatten layers/transparency | No crop/trim marks, bookmarks, comments, annotations, placeholders, security; single pages | 650 MB max; 7 pt minimum type; 24-page minimum; barcode may be supplied or KDP places one |
| IngramSpark POD | One complete interior PDF plus separate complete cover PDF | Interior: 0.125 in top, bottom, outer only; cover generally 0.125 in, with product exceptions | 300 ppi recommended | Fonts embedded; B&W art grayscale; cover CMYK; no spot colors/ICC profiles per checklist | No crop/registration marks; single-page 1-up; full file required for revisions | 0.5 in safe margin recommended; cover barcode mandatory and placed if absent; current template required |
KDP currently scales the minimum inside margin by page count. For 24–150 pages it lists 0.375 inch; 151–300 pages, 0.5 inch; 301–500 pages, 0.625 inch; 501–700 pages, 0.75 inch; and 701–828 pages, 0.875 inch. Outside minimums are at least 0.25 inch without bleed and at least 0.375 inch with bleed. These are platform minimums, not universal design recommendations.
KDP also states that a full-bleed interior PDF extends 0.125 inch beyond the top, bottom, and outer trim edges, making the submitted page 0.25 inch taller and 0.125 inch wider than the trim. Do not add interior bleed at the gutter unless the specific printer says to do so.
Duplicate the approved manuscript and clean the production copy. Show hidden characters. Remove repeated spaces, manual tabs used for indents, empty paragraphs used for vertical spacing, hard returns inside ordinary paragraphs, and manual page numbers. Preserve intentional line breaks, poetry, tables, lists, notes, and scene separators.
Apply named styles to every structural element: body first paragraph, body indented, chapter number, chapter title, heading levels, block quotation, extract, list, caption, footnote, running head source, and back matter. A style change should update every occurrence; manual formatting should be exceptional and documented.

Problem |
Before | After | Why it matters |
Verify |
| Manual paragraph indents | Tab character at every paragraph | Body style with first-line indent | Global control and clean reflow | Show hidden characters; inspect exceptions |
| Vertical spacing | Three empty returns before chapter title | Chapter-opener style or master-page rule | Prevents shifting and inconsistent openers | Scan all chapter starts |
| Scene break | Blank line that may disappear | Named scene-break style with approved ornament or space | Preserves intentional structure | Compare with editorial source |
| Local heading formatting | Bold, 18 pt, centered by hand | Heading style linked to hierarchy | Consistent contents and navigation | Generate contents and audit headings |
| Low-resolution figure | 900 px image stretched to 6 in = 150 ppi | 1800 px or greater at 6 in = 300 ppi | Reduces visible pixelation | Check effective resolution at final size |
| Printed page furniture | Header and folio on chapter opener/blank page | Correct master suppresses excluded elements | Produces professional page sequence | Thumbnail scan plus physical proof |
Search-and-replace can create errors when it ignores context. After every bulk cleanup, review the changed locations or compare versions. Do not globally remove all double returns if the manuscript uses them for scene breaks; first convert those breaks to a named marker or style.
Build a signed-off sequence before pagination. A common print order may include half title, series page, title page, copyright page, dedication, epigraph, table of contents, foreword, preface, acknowledgments, body, appendices, notes, bibliography, index, about the author, reading-group material, and other books. Not every book needs every element.
Page numbering and displayed folios are separate decisions. Early front matter may be counted without a visible number; later front matter may use Roman numerals; the main text commonly begins Arabic numerals. Confirm whether the first chapter opens on a recto page and how intentionally blank pages should be handled. “Blank” pages must not accidentally carry a running head or page number.
Place the correct edition ISBN in the copyright-page metadata when the publishing plan calls for it. A paperback, hardcover, and separately sold ebook edition generally require distinct ISBN decisions. An ISBN identifies an edition and format; it does not create copyright or guarantee distribution.
The barcode belongs to the cover workflow, not the interior-typesetting workflow. KDP allows a cover to be uploaded with or without a barcode and says it will place one when the publisher does not supply one. IngramSpark says barcodes are mandatory on covers and will place one if missing. If you supply your own barcode, use the destination’s size, color, quiet-zone, safe-area, and placement rules. Do not add a barcode to the interior PDF merely because the ISBN appears on the copyright page.
Authors who want their own name or business shown as publisher of record should decide ISBN ownership before finalizing metadata. Compare the Custom ISBN and Basic ISBN options, then verify that the selected platform accepts the identifier and publishing arrangement.
Create document sections, master pages, or templates for each recurring page type: chapter opener, ordinary text, part title, figure page, notes, bibliography, and blank verso. Set trim, margins, columns, baseline grid if used, running heads, folios, and section starts before flowing the entire book.
Use mirrored left/right pages. The inner margin must change sides automatically. Running heads should reflect the approved hierarchy and disappear on chapter openers, part titles, blank pages, and other excluded pages. Confirm that page numbers sit inside the safe area and remain visually balanced across a spread.
Print six representative spreads at 100% on paper, trim them to size, and place facing pages together. Include the densest paragraph, shortest chapter, longest heading, widest table, largest figure, and a page near the center of the book. A layout that looks comfortable on a large monitor can feel cramped at actual size.
Choose typefaces licensed for the intended print and digital use. Verify that each font includes the required weights, italics, small caps, numerals, punctuation, language characters, and symbols. Do not manufacture italics, bold, or small caps with a software effect when the real font style is available.
Set body size, leading, paragraph indents, space before and after, hyphenation, justification, tracking limits, headings, extracts, lists, captions, notes, and folios as a coherent system. The correct values depend on typeface, line length, trim, audience, paper, and content. A generic “11-point font with 0.5-inch margins” is not a design system.
Review color and texture across a full spread. Fix loose and tight lines, ladders of hyphens, rivers, collisions, unintended word stacks, short last lines, and distracting repeats. Widows and orphans are not always defined identically across style guides, so document the house rule and apply it consistently.
Prefer local paragraph adjustments, discretionary hyphens, tracking within a controlled range, or editorially approved wording changes. Do not solve one page by shrinking the whole book, forcing arbitrary line breaks, or applying invisible text.
Place linked or embedded production assets at their final printed dimensions. Effective resolution is the source pixel dimension divided by the final physical size. A 1,200-pixel-wide image printed four inches wide has 300 pixels per inch; the same image stretched to eight inches has 150 pixels per inch.
Use the printer’s color instructions. A black-and-white interior usually needs grayscale art, while color interiors and covers may require a specific CMYK workflow. Thin lines, rich black mixtures, spot colors, transparency, and ICC profiles can behave differently in automated print production. Follow the destination specification rather than guessing.
Flow the entire manuscript, update generated tables of contents and cross-references, and then review from page one to the end. Do not judge pages in isolation. A correction to an early chapter can reflow everything after it.
Check chapter starts, facing-page relationships, blank pages, running heads, folios, footnotes, continued tables, figure placement, recto/verso logic, and the index after final pagination. Rebuild or verify any index against the exact final page numbers. A static index copied from a prior edition is not reliable.
Export a separate, single-page interior file—never reader spreads or two-up printer spreads unless the printer explicitly requests them. Use the destination’s page size, bleed, PDF preset or standard, compression, color, font embedding, and mark settings. Printer marks are commonly prohibited for print-on-demand uploads.
For KDP, the public submission guidance currently says full-bleed interiors must be PDF; no-bleed interiors may be PDF, DOC, DOCX, RTF, HTML, or TXT, which KDP converts to PDF. A controlled PDF is generally the safer production handoff because it preserves pagination. KDP lists a 650 MB maximum file size, asks that fonts and images be embedded in the native file, requires transparency and layers to be flattened, and disallows crop marks, trim marks, bookmarks, comments, invisible objects, annotations, placeholder text, and metadata.
KDP currently requires images at least 300 DPI and recommends no more than 600 DPI to help keep processing manageable. It lists a seven-point minimum font size and a 24-page minimum, while the maximum page count varies by trim, paper, and ink. Verify all of those values again for the selected configuration.
IngramSpark’s public print-file checklist calls for one complete interior PDF and one complete cover PDF, supplied separately. It specifies single pages, embedded fonts, no crop or registration marks, 0.125-inch bleed on the top, bottom, and outside edges for bleeding interiors, and recommends 300 ppi images. It also recommends a 0.5-inch margin from trim for non-bleeding text and art.
Open the exported PDF in a preflight-capable viewer. Do not assume a successful export equals a valid print file. Inspect document properties, page boxes, page count, fonts, image resolution, color spaces, transparency, security, annotations, and file size.

Render every page to images or thumbnails and scan the sequence for unexpected blanks, repeated pages, missing graphics, shifted content, and sudden margin changes. Then compare the page count and section starts against the layout source. Automated checks find mechanical problems; a human must still judge legibility and meaning.
Upload the interior and the platform-generated or template-based cover. Review every warning. Use the platform previewer at maximum zoom and inspect trim, bleed, safe areas, page sequence, spine, barcode area, and all detected issues. A previewer is an additional test—not a substitute for preflight.
Order a physical proof whenever the platform and schedule allow it. Review it under normal reading light and compare it with the PDF. Inspect trim variance, gutter comfort, opacity/show-through, image tone, small text, line weight, binding, cover color, spine alignment, lamination or finish, barcode scan, and the physical rhythm of page turns.
Mark corrections on the proof, update the editable source, re-export the complete files, rerun preflight, re-upload, and review again. Do not patch the PDF by moving individual elements unless the source and change log are also updated; otherwise the archive will not reproduce the released edition.
Hugh Howey’s 2014 tutorial remains useful as an example of learning print layout, using InDesign templates, and ordering a physical proof. Its CreateSpace platform references, templates, price example, and upload route are historical. CreateSpace publishing services were consolidated into KDP, so authors should use current KDP templates and specifications rather than the old files.
Cause: the layout was built at manuscript size or exported without the required bleed. Fix: return to the document setup, confirm the selected trim, add only the required bleed edges, reflow if necessary, and export again. Do not scale a finished PDF blindly; scaling can change type size, margins, and image resolution.
Cause: font embedding was disabled, the license forbids embedding, or a style uses a missing font. Fix: audit every font/style, replace unlicensed or unavailable fonts, embed according to the destination, export, and confirm the actual PDF font list. Converting all text to outlines removes searchability and can damage hinting; do it only when the printer specifically requires it.
Cause: low source resolution, enlargement in layout, aggressive compression, or a screenshot used as production art. Fix: replace the source, reduce the printed size, export with appropriate compression, and verify effective resolution. Changing a metadata label from 72 to 300 DPI does not create pixels.
Cause: art stops at trim, transparency flattening creates seams, or the previewer renders tile boundaries. Fix: extend art to the full bleed boundary, flatten with the approved export preset, inspect at multiple zoom levels, and ask for a proof. Determine whether the line exists in output, not only in screen rendering.
Cause: the inside margin is too small for page count and binding, or mirrored margins are not working. Fix: apply the selected platform’s minimum, add design comfort beyond the minimum when needed, verify left/right master pages, and inspect a bound proof.
Cause: a master page or section rule applies too broadly. Fix: assign the correct page template, suppress furniture on excluded pages, and scan the entire page sequence after reflow.
Cause: interior corrections changed the final page count, paper or ink changed, or an old template is being reused. Fix: lock the interior, obtain a fresh cover template or recalculate with the platform tool, rebuild the cover, and re-preflight. The cover should be finalized after the print interior page count is stable.
Cause: incorrect color, resolution, size, quiet zone, placement, or duplicate platform placement. Fix: follow the destination cover specification, keep the reserved area clear, and decide whether the platform or publisher supplies the barcode. Confirm that the encoded ISBN matches the released edition.
Yes for some simple interiors when the operator controls styles, sections, margins, page furniture, images, and PDF export. It becomes risky as layout complexity grows. The destination specification and the quality of the final PDF matter more than the tool’s name.
A double-spaced, 12-point, letter- or A4-size manuscript is a common editorial submission format, as the Reedsy manuscript guide explains. It is not the final print-book layout. The typeset book uses its own trim, typography, leading, margins, and page architecture.
Use effective pixels per inch at final printed size and follow the printer. KDP currently states a minimum of 300 DPI and recommends a maximum of 600 DPI; IngramSpark recommends 300 ppi. Line art and special printing may have different needs. Merely changing the DPI label does not improve a low-resolution image.
Only when the platforms and selected products have identical interior specifications and the layout remains appropriate. Cover files cannot be reused because binding, board, wrap, spine, and template dimensions differ. Treat each format as a separate production configuration and verify its edition metadata and ISBN decision.
No. The human-readable ISBN may appear on the copyright page; the retail barcode belongs on the cover or is applied by the platform. Follow the selected platform’s current cover process and encode the ISBN for that edition.
Usually not. A print PDF fixes every page for manufacturing. A standard EPUB is typically reflowable so readers can change font, size, and display. Fixed-layout ebooks are a specialized case. Build and test the ebook as a separate deliverable instead of converting the print PDF blindly.
Order at least one when possible, and order another after material corrections, platform changes, paper/ink changes, or cover-template changes. The correct number depends on schedule and risk. A physical proof is particularly important for color, full bleed, small type, dense tables, unusual trim, and thick books.
The fastest route from manuscript to book is not skipping checks. It is making the decisions in the correct order: freeze the text, select the product, structure the source, build the layout, export to the live specification, preflight the files, inspect the platform preview, and approve a physical proof.
Good typesetting feels invisible because the system works. Readers can follow the text, pages turn naturally, images reproduce as intended, metadata identifies the edition, and the printer receives files it can manufacture consistently. That result comes from a controlled workflow—not from a single “save as PDF” command.
