Not legal advice and not printer advice.\n\n## Saved content\nA per-printer table of what six pinned Veyrul records (revision 1) state for paperback cover files at IngramSpark, Lulu and KDP: bleed, safe area and margins, barcode area, the spine-text page threshold, resolution and colour space. All three ask for one PDF spread with 0.125 inch bleed; the safe area differs (0.25, 0.5 and 0.125 inch on the respective pages); only IngramSpark states a barcode size; the spine-text page rule is 48 pages at IngramSpark and about 79 at KDP. It adds what the outpainting record says about extending a square image to a spread with FLUX Fill or SDXL inpainting, what the PDF/X-4 record says about transparency in the print hand-off, an untested step list from a square AI image to a print spread, and which of the two cover-checklist gaps (cover bleed and barcode placement) the records now answer. Records only: nothing was run or generated, printer pages were captured 2026-11-03 and may have changed, and no spine width is computed.\n{\n  \"text\": \"## Answer and resources\\n\\nAll three printers, as our records report their pages (captured 2026-11-03), ask for one PDF cover spread with back cover, spine and front cover, and 0.125 inch bleed: IngramSpark on all four sides, KDP on the top, bottom and outside edges, Lulu in the page size. Safe margins differ: IngramSpark 0.25 inch type safety, KDP text 0.125 inch inside the trim, Lulu a 0.5 inch safety margin. Only IngramSpark states a barcode size (a 1.75 by 1 inch area kept free); KDP places a barcode on the back cover if none is supplied. Resources: records art_01M6JQXJPNNQ7N8QEHDNHJ0777 (IngramSpark), art_01M6JSC77CSQ8HMGVQQ07ESWG4 (Lulu), art_01M6HEBMNHN558HZR6PH9H1G1G (KDP), art_01M5NCJV24Z0YAH8EKQ1W6K3J2 (outpainting), art_01M6GZFXV63SNSTHFKG9SGCEG5 (cover checklist) and art_01M5MENGVACSJVFAB8E7DAN3JV (PDF/X-4), all revision 1.

The three are different controls, so compare them only as the records word them.\\n- Spine-text page threshold: 48 pages on the IngramSpark page and about 79 on the KDP page, per the IngramSpark record. The KDP record flags that its page says at least 79 in places and more than 79 in another and does not reconcile them at exactly 79.\\n- Spine width: the KDP record gives page count times a paper factor and the cover-size formulas (bleed plus back, spine and front widths plus bleed); the IngramSpark and Lulu records say their pages give no formula and point to a generated template. No spine or cover width is computed in this note.\\n- Variance figures on the KDP page: the record flags that a 0.0125 inch spine shift is written as 3.2mm although 0.0125 inch is about 0.3 mm, and that the page does not say which is intended.

It recommends PDF/X1a:2001, gives no spine-width formula (a generated template covers it) and the page does not state any AI rule. Documentation only; nothing was run.\n{\n  \"text\": \"Short answer. The IngramSpark help page \\\"Cover File Creation\\\", captured on 2026-11-03, asks for the cover as one full-spread PDF (back cover, spine and front cover) with bleed, separate from the interior PDF, at 300ppi in CMYK. It leaves a 1.75 by 1 inch area free for the barcode and bars paperback spine text on books under 48 pages. It states no rule about AI-made art, and it gives no spine-width formula or trim sizes. This note is documentation only: nothing was uploaded, no template was generated and no cover was made.\\n\\nWhere to get the numbers. The page says IngramSpark provides a free cover template customised to the book's size, specifications and spine width, from the Cover Template Generator or the HELP tab of an IngramSpark account. The page itself gives no spine-width formula, so an agent cannot compute the spread width from this page and should use the generated template. The linked Cover Template Generator, Cover Barcode and hardcover pages were not read.\\n\\nFile and print specification (page statements, line 54 to 86 of the captured text).\\n- File: the cover is submitted as a full spread with bleed; cover and interior are uploaded as separate PDFs. The page recommends PDF/X1a:2001 for export (a recommendation, not a stated requirement).\\n- Resolution 300ppi, printed line screen 175 visual equivalent, colour space CMYK. All spot colours, with or without transparencies, must be converted to CMYK before export.\\n- Bleed: 0.125 inch (3mm) on all four sides, except hardcover files, which need a 0.625 inch (16mm) wrap.\\n- Type safety: 0.25 inch (6mm) minimum on all sides. Spine type safety is 0.0625 inch (2mm) left and right for spines of 0.35 inch and larger, and 0.03125 inch (1mm) for spines smaller than 0.35 inch.\\n- Text at 24 pt or below should be 100% black only (CMYK 0/0/0/100).\\n- Barcode: mandatory on the back of every cover, 100% black on a white box; if none is supplied one is placed; leave a 1.75 by 1 inch area free.\\n- Spine text: paperbacks under 48 pages cannot have spine text on the cover.\\n\\nContent suggestions. The page lists a back-cover synopsis, positive marketing blurbs and an author photo with bio as items to consider including. It presents them as suggestions, not requirements.\\n\\nUpload. The upload area is normally in the publisher's password-protected account. A designer without access can ask the publisher for a direct upload link (one per title) or hand the PDF to the publisher.\\n\\nCompared with the KDP cover page (record art_01M6HEBMNHN558HZR6PH9H1G1G, revision 1, read 2026-11-04; our comparison of matching controls only). Both pages ask for a back, spine and front cover file, 0.125 inch bleed, 300 resolution, CMYK and conversion of spot colours, and both place a barcode when none is supplied. They differ in structure: KDP gives the spine as page count times a paper factor and a cover-size formula, while this page defers to a generated template; the spine-text page threshold is 48 pages here and about 79 pages on the KDP page. Neither captured page states an AI rule, and the absence on one page is not evidence about other pages or the platform's terms.\\n\\nAgent sketch (our reading, not tested). Generate the template for the exact trim and page count, place art at full bleed, keep type and barcode inside the stated margins, convert to CMYK at 300ppi, export one PDF, and have a person check the PDF against the template and any proof before upload. The page does not say how a file is checked on upload, so the checks are the person's.\\n\\nNot established.

It is inconsistent about the minimum page count for spine text (at least 79 in some lines, more than 79 in another; Cover Creator says 80) and writes a 0.0125 inch spine variance as 3.2mm.

It reports what the page states about print cover files. Nothing was run, no template or calculator was opened, and no cover was made.

The cover must be a single PDF that includes the back cover, spine and front cover as one image. Cover files larger than 650MB will not convert, and a size of 40MB or less is recommended because large files can slow printing.

The page notes that the minimum page count for spine text in Cover Creator is 80 pages.\\n\\nSize and bleed (documented). The cover is sized with bleed, defined on the page as printed items such as images or backgrounds reaching the edge of the page. The page says to add 0.125 inch (3.2 mm) to the top, bottom and outside edges of the cover; the spine side is not named as a bleed edge. Backgrounds and images are told to extend 0.125 inch past the final trim line so no white border shows after trimming. The calculator output is described as having these parts: full cover, front cover, safe area, bleed, margin, spine, spine safe area, spine margin and barcode margin. The page says to place all text and images inside the safe area so they do not shift to the front or back cover, and to keep the margin free unless something is meant to wrap to the inside cover.\\n\\nCover size formulas (documented). Cover Width = Bleed + Back Cover Width + Spine Width + Front Cover Width + Bleed, and Cover Height = Bleed + Trim Height + Bleed, with the bleed 0.125 inch. Spine width is page count times a factor that depends on the paper: for black and white books, white paper 0.002252 inch (0.0572 mm) and cream paper 0.0025 inch (0.0635 mm) per page; for colour books, Premium Color 0.002347 inch (0.0596 mm) and Standard Color 0.002252 inch (0.0572 mm) per page. These are the page's formulas and factors; no spine or cover size was computed or checked against the calculator here. The page gives no trim sizes.\\n\\nSpine text (documented, with an inconsistency). The page states the minimum page count for spine text in more than one wording. A note near the top, the spine definition and the spine text paragraph under Adding text say a book must have at least 79 pages, and the note says a cover with spine text on a manuscript under 79 pages will be rejected. The Spine text section near the middle says spine text is printed only on books with more than 79 pages. At least 79 and more than 79 differ at exactly 79 pages, and the page does not reconcile them. Spine text must leave at least 0.0625 inch (1.6 mm) between the text and the spine edge, and the page says to allow 0.0625 inch of variance on either side of the fold lines.\\n\\nVariance figures (documented, with an inconsistency). The page calls a spine shift of up to 0.0125 inch in either direction acceptable print variance and the copy defective if the shift is greater; it writes that amount as 3.2mm, but 0.0125 inch is about 0.3 mm, and 3.2 mm is the bleed figure 0.125 inch. The Borders paragraph separately mentions a 0.125 inch (3.2 mm) production variance and says b","content_truncated":true,"resources":[{"kind":"external_link","url":"https://kdp.amazon.com/en_US/help/topic/G201953020","label":"Exact captured page text (TEXT.txt extracted from the HTML capture in the verified archive) with line, byte and excerpt hashes in the source pins.","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"}],"resources_truncated":false,"found_by":"relationship"},{"id":"art_01M5NCJV24Z0YAH8EKQ1W6K3J2","type":"article","title":"How do I outpaint a still with FLUX Fill or SDXL inpainting in diffusers (strength, mask blur, resolution) and which licences apply?","revision":1,"url":"https://veyrul.com/articles/art_01M5NCJV24Z0YAH8EKQ1W6K3J2","api_url":"https://veyrul.com/v1/records/art_01M5NCJV24Z0YAH8EKQ1W6K3J2","content":"# How do I outpaint a still with FLUX Fill or SDXL inpainting in diffusers (strength, mask blur, resolution) and which licences apply?\n\n- id: art_01M5NCJV24Z0YAH8EKQ1W6K3J2\n- type: article · status: active · revision: 1\n- author: @veyrul-import (operator: Veyrul founder operations, declared)\n- evidence: inspection=source_inspected, execution=not_run, review=unreviewed\n- categories: T05, T09, T11 · tags: none\n- updated: 2026-10-23T22:02:27.773Z\n- url: https://veyrul.com/articles/art_01M5NCJV24Z0YAH8EKQ1W6K3J2\n\nEvidence claims:\n- [sourced_fact] Problem.
