What QinPrinting Formatting Actually Covers

QinPrinting is an offset press based in China that handles trade paperbacks, premium hardcovers, photobooks, and illustrated children’s titles for independent authors and small publishers worldwide. Unlike print-on-demand vendors that accept loose PDFs and auto-correct minor issues, an offset workflow expects fully print-ready files that match the press’s exact technical contract. Word-2-Kindle prepares your interior and cover to that contract so the QinPrinting pre-press team can plate your job without kickbacks, revision rounds, or surprise re-quotes after file review.

The deliverables are two separate PDF/X-1a:2001 files: one interior bound to the trim size, one cover sized to wrap front, spine, and back as a single flat artwork. Both files are built around the paper stock and binding style locked at the quote stage, because spine width, bleed behavior, and color profile all shift with those choices. We work from your manuscript, your cover artwork, and the QinPrinting quote sheet, and we deliver files that match the spec line-for-line.

Offset PDF/X-1a:2001 Specifications

Offset prepress is stricter than digital print. Every image is converted or verified at 300 DPI minimum at final placed size, with line art at 600–1200 DPI to keep edges sharp on plate. All color is converted to CMYK against the appropriate ICC profile — FOGRA39 for coated European-style stocks and GRACoL 2006 (or G7) for North American coated jobs — with uncoated work mapped to the matching uncoated profile when paper calls for it. Bleed is set at 0.125 inches on all outer edges, fonts are fully embedded or outlined, transparency is flattened, and overprint is checked so black text does not knock out unexpectedly. The exported PDF/X-1a:2001 carries the output intent inside the file, which is what QinPrinting’s preflight reads first.

Bindings and Paper Choice

Binding drives spine math and interior margin behavior. Perfect bind covers paperbacks and absorbs roughly 0.125 inches into the gutter, so inside margins are widened accordingly. Smyth-sewn signatures suit premium hardcovers and lay flatter over time. Spiral bind is used for cookbooks and workbooks where pages must lay open. Layflat photobook construction keeps two-page spreads continuous across the gutter without image loss. Paper is locked at quote: Munken Pure cream and Munken Lynx white are common uncoated novel stocks, while gloss-coated and matte-coated stocks suit illustrated and photo titles. We compute spine width from page count multiplied by the exact PPI (pages per inch) value of the chosen paper, then build the cover wrap around it.

Why Authors Choose QinPrinting Formatting

• PDF/X-1a:2001 export tuned to QinPrinting’s preflight, with output intent embedded.
• Correct ICC color profile applied (FOGRA39 or GRACoL) based on paper finish.
• Spine width calculated from page count and verified PPI of the locked paper stock.
• Cover wrap built as a single PDF spanning back, spine, and front with bleed.
• Pre-press color proofing guidance: soft-proof PDF, digital proof, or physical Cromalin.

FAQ

Do I need separate files for the interior and the cover?
Yes. QinPrinting requires one PDF/X-1a:2001 for the bound interior at trim size with bleed, and a second PDF for the cover built as a single wrap that includes back, spine, and front in one flat artwork.

Which color profile should the files use?
It depends on the paper finish quoted. Coated stocks typically use FOGRA39 or GRACoL 2006; uncoated novel stocks use the corresponding uncoated profile. The output intent is embedded in the PDF/X-1a:2001 so preflight reads it directly.

How is the spine width calculated?
Spine width equals page count multiplied by the pages-per-inch value of the locked paper stock, plus any binding allowance specified by QinPrinting for that bind style. The cover wrap is built around that exact dimension.

Is a physical proof necessary before the full run?
It is recommended for color-critical work such as photobooks and illustrated titles. Options include a soft-proof PDF, a digital press proof, or a physical Cromalin proof matched to the production profile.

Can the same files be used for Amazon KDP or IngramSpark?
No. POD vendors use different bleed, spine math, color profiles, and cover template dimensions. A separate POD-formatted file set is prepared when distribution through KDP or IngramSpark is also planned.
