Preparing Scanned Books for Kindle and E-Ink Readers
A paperback page and an e-ink screen are very different pieces of paper. Raw scans that look fine on a monitor become tiny, grey, and tiring on a small reader. ScanTailor Advanced’s Page Layout stage — uniform margins and a consistent page size — is what turns a stack of scans into a book that is actually pleasant to read on e-ink.
Why raw scans read badly on e-ink
- Scale. A scanned A5 or hardcover page is physically larger than most e-reader screens. Shown whole, the text shrinks to a size nobody can read for a chapter at a time.
- Wasted margins. The original book’s margins — designed for thumbs and binding — waste a large share of a small screen on blank space while the text stays small.
- Inconsistency. Raw scans vary: slightly different page sizes, shifting text blocks, a few crooked pages. On a monitor you barely notice; on e-ink, where every page turn is a slow refresh, a wandering text block is a constant small annoyance.
- Grey, low-contrast pages. Camera and scanner output carries shadows and off-white paper tones that e-ink renders as muddy grey, tiring the eye and draining contrast the screen cannot spare.
Every one of those problems is a page-preparation problem, not a reader problem — which is why they get fixed in ScanTailor, before the file ever reaches the device.
The ScanTailor work that matters most here
Uniform page size and margins (Page Layout)
The Page Layout stage is the heart of this workflow. Set one page size for the whole book and margins that are deliberately tighter than the printed original: on an e-reader, margin is screen area stolen from the text. Uniformity matters as much as the values — when every page shares the same geometry, the text block sits in the same place on every page turn. Use the batch workflow so the settings genuinely apply book-wide, and check a chapter with mixed content (a chapter title page, a dense text page, an illustration) before exporting everything.
Straight and clean before it is small
Deskew and, for bound books, dewarping matter more on a small screen, not less: a slightly tilted line that is a shrug on paper becomes a visible sawtooth when scaled down. Likewise, black-and-white output with a careful threshold gives e-ink the deep blacks it renders best; our threshold guide covers choosing a method that keeps thin letterforms intact. For illustrated books, mixed mode keeps pictures in grayscale while the text goes crisp black-and-white.
Crop to the content, honestly
Select Content should hug the real text block. Every millimetre of scanner bed and shadow you leave in is screen area the reader wastes. Equally, do not crop into page numbers or running heads if you rely on them for orientation in a long book — decide once, apply consistently.
From cleaned pages to the device
ScanTailor outputs page images, not ebooks, and it does not assemble documents — so there are two honest delivery routes:
Route A: PDF
Assemble the cleaned pages into a PDF (optionally with an OCR text layer via the searchable-PDF workflow) and send the PDF to the reader. This preserves your exact page layout — what you set in Page Layout is what you get — and is the most predictable route for scanned books, whose pages are images by nature.
Route B: Calibre
Calibre is a free, open-source ebook manager. Per its own description, it can convert dozens of file types, transfer books to almost every e-reader, and automatically send the best format for the device, converting when needed; conversions can also adjust margins and build a table of contents. Add the book to Calibre, convert or send, and let it handle device specifics.
Set expectations for scanned books: a scanned page is a picture of text, not text. It will not reflow to a bigger font the way a born-digital ebook does, and Calibre conversion cannot invent reflowable text from pictures. If true reflow matters — large-print reading, for example — the path is OCR into a text-based format (see the OCR workflow), accepting that formatting will be simpler than the printed page.
Reading-comfort checklist
- Read one full chapter on the actual device before processing the rest of the series — comfort problems are obvious in five pages and expensive after five hundred.
- Prefer slightly larger effective text over maximum words per screen; e-ink reading is a marathon.
- Check a page with italics and a page with footnotes: small print is where aggressive binarization shows first.
- Keep the cleaned masters. If you change readers — bigger screen, different format — you will rebuild the reading copy from them, not rescan.
- For the capture side of the next book, our scanning hardware guide covers overhead, flatbed, and camera setups — even, shadow-free capture makes everything on this page easier.
Frequently Asked Questions
Can ScanTailor send a book directly to my Kindle or e-reader?
No. ScanTailor outputs cleaned page images and does not assemble documents or talk to devices. Assemble the pages into a PDF, or manage and transfer the book with a tool such as Calibre, which supports almost every e-reader and converts formats when needed.
What is the single most important ScanTailor stage for e-ink?
Page Layout. Uniform page size and deliberately tight, consistent margins decide how large the text can appear on a small screen. Deskew and clean binarization come next — small screens amplify crooked lines and grey, low-contrast pages.
Why won’t my scanned book reflow like a normal ebook?
Because each page is a picture of text, not text. Reflow requires recognized, structured text, which means running OCR and building a text-based edition — a different product from a faithful scanned-page book, with simpler formatting.
