We also offer square formats such as 210mm × 210mm, as well as fully customizable dimensions based on your specific requirements.
Our hardcover bindings are designed to handle between 24 to 400 pages, depending on the paper weight. For example, lighter paper like 100 or 115 gsm can support books from 24 up to 400 pages, while mid-range weights such as 130 and 150 gsm are ideal for 36 to 400 pages. Heavier options like 170 or 200 gsm maintain durability and quality within a 24–400 page range.
When it comes to paper selection, you can choose from premium silk coated paper, glossy art paper for high-shine visuals, eco-friendly recycled paper, or natural uncoated paper for a more organic reading experience. These options allow your hardcover books to meet both aesthetic and environmental preferences.

❓How to Prepare Files for Hardcover Book Printing at Jinguan
📁 File Format
Please upload two PDF files: one full cover file (front cover, spine, back cover) and one file with all inner pages as single pages. Keep each file under 2GB. Contact us if your files are larger.
🎨 Color Setup
Use CMYK color mode with 300dpi resolution. Text should be 100% black. If printing in grayscale, convert before uploading. RGB files will be converted to CMYK automatically, which may slightly change colors.
✂️ Bleed and Quiet Zones
Add 3mm bleed and 3mm safe margin on inner pages. For the spine, use an 8mm safe margin to avoid cutting or bending important content.
📕 Hardcover Cover
Cover includes front, spine, and back in one spread. Allow extra area for wrapping. We recommend lamination to prevent cracking. Add 20mm bleed on all edges, 5mm hinge bleed on both spine sides, and 20mm bleed top and bottom.
📄 Endpapers
We offer various endpaper options. Contact customer service if you need printed endpapers or help with design.
✅ Final Check
Page count must be a multiple of 4; add blank pages if needed. Review your proof carefully before ordering. We ensure high quality for both small and bulk hardcover orders.
