How books are printed and bound in India
Overseas publishers print in India for children's picture books, colouring and activity books, educational titles and illustrated non-fiction. Sivakasi in Tamil Nadu, long known for printing, has a printing cluster with a completed common facility centre under the Ministry of MSME's cluster programme. Large book printers also work from Delhi NCR, Mumbai, Chennai and other cities, so the printer's own set-up matters more than the town.
A book is printed on large sheets, usually by sheet-fed offset. Each sheet is folded into a signature of 8, 16 or 32 pages. Signatures are gathered in order, bound and trimmed on three sides. The main bindings are:
- Perfect binding. The spine edge is milled and glued with hot-melt adhesive into a wrap-around cover. PUR adhesive holds pages far better than EVA, especially with coated paper.
- Section sewn. Signatures are sewn through the fold, then glued. Used for books that must open flat and last.
- Case binding. Sewn or glued pages attached by endpapers to a hard cover of board wrapped in printed paper or cloth.
- Saddle stitching. Wire staples through the fold, for thin activity books.
- Board books. Printed sheets laminated onto thick board and die-cut, for very young children.
What we check on printed books
| Check | How it is checked | What fails |
|---|---|---|
| Collation | Every page of each sampled copy turned in order; folio numbers and signature marks on the spine checked | Missing, doubled, swapped or upside-down signatures; blank pages |
| Binding strength | Pages pulled by hand at the start, middle and end; book opened flat and flexed; for agreed lots, a page-pull tester reading against your target | Pages loosening, cracked glue line, sewn thread breaking |
| Colour | Sampled pages compared with the signed press proof under a light booth; repeated colours compared across signatures | Colour cast, skin tones off, density varying through the run |
| Print quality | Loupe and visual check of images and small type | Misregistration, hickeys, set-off, ink smears, broken type |
| Trim and squareness | Height and width measured; corners checked with a square; images that run off the edge checked for white slivers | Off-size, out of square, text trimmed into, crooked trim |
| Cover | Cover position on the spine, spine text centring, lamination and hinge crease | Spine text wrapping onto the front, lamination bubbling or lifting |
| Text and identifiers | ISBN, price and title on cover and imprint page against the approved file; barcode scanned | Wrong ISBN or edition, barcode not scanning, origin line missing |
| Paper | Grammage of a cut leaf; grain direction checked by tearing and folding a waste copy | Lighter paper than ordered; grain across the spine |
Common printed book defects and how they are classed
| Defect | Typical cause | Class |
|---|---|---|
| Small detachable part on a book for children 3 and under | Novelty part, button or toy not fixed to the book | Critical |
| Missing, doubled or inverted signature | Gathering error, signature fed upside down | Major |
| Pages coming loose | EVA glue on coated paper, spine not milled deep enough, glue too cold | Major |
| Wrong ISBN, title or edition text | Old plate or file used | Major |
| Colour clearly off the proof | Ink density drift, wrong profile | Major |
| Pages wavy or book won't close flat | Paper grain across the spine, damp paper | Major or minor by severity |
| Set-off or small hickeys | Stacking before ink dried, dust on the blanket | Minor |
| Scuffed or dented corners | Handling, loose cartons | Minor |
Your defect list decides the final class. Agree in advance how many copies may be cut open or pulled for binding tests.
Market rules for printed books
- Children's books, US. CPSC grants a testing exemption from the lead content limit for ordinary books: printed on paper or cardboard with inks or toners, bound and finished in a conventional way, and meant to be read or to teach. The exemption does not cover books with inherent play value, books designed or intended for children 3 and under, or a toy or other item sold or packaged with the book. A certificate relying on it must cite Public Law 112-28 and say the book meets the ordinary book definition. See CPSIA children's products.
- Book-and-toy sets. A plush toy, crayons or a puzzle packed with a book is assessed as its own product. In the EU that means toy rules for the toy; see EN 71.
- General safety, EU. Books are consumer products under the General Product Safety Regulation, which asks for identification and a responsible economic operator in the EU. See EU GPSR.
- EUDR. Regulation (EU) 2025/2650 deleted printed books and other chapter 49 products from Annex I of the EU Deforestation Regulation in December 2025, so they need no due diligence statement. Notebooks and diaries stay in scope as chapter 48 goods.
- Origin and FSC. "Printed in India" on the imprint page; an FSC logo only with a valid chain-of-custody certificate for the printer. See origin labelling.
Packing, transit and your purchase order
Books are heavy for their size and damage at the corners. They should be packed tightly so they cannot slide, spine to fore-edge in alternating layers, shrink-wrapped where the publisher asks, in five-ply cartons sized to the book. Damp paper waves and curls, so the inspector checks moisture on stock and looks for cartons stored on bare floors. Pallets need corner boards and must not overhang.
Put these in your purchase order:
- Trim size, extent (page count), paper grade and grammage for text and cover.
- Binding method and adhesive (PUR or EVA), and a page-pull target if you have one.
- Signed press proofs and the colour standard; which pages are colour-critical.
- ISBN, barcode position and the imprint page text, including "Printed in India".
- Age grade, and whether the book has any non-paper parts.
- Copies per carton, carton grade, shrink-wrap and pallet specification.
- FSC claim and certificate number, if used.
Printers often make notebooks and journals on the same lines. Book an inspection in Sivakasi or anywhere in India.
