All book printing files must be in Adobe PDF format, all content pages combined into 1 pdf file and cover file submitted separately. Please review the following specifications before submitting your artwork. If there are difficulties complying with the requirements, let us know and we will try to assist you.
Spine Width: Contact us or use this Spine Width Calculator for exact measurement according to your page count and paper stock. Hardcover books will require a minimum of 4mm spine when less than 24 pages.
Color Mode: Color in CMYK, images with minimum 300dpi.
Marks & Bleed: The bleed requirement will be minimum 1/8 inch or 3mm (preferably 1/4 inch or 6.35mm). If artwork has no bleeds, no bleed margin is required.
Spine Gutter: No spine gutter is required for inner pages of casebound smyth sewn books (layflat). For perfect bound (paperbacks), glue bound or limp bound books, leave minimum 1/2"(0.5 inch) to 1" (1 inch) gutter/margin to the spine of the book.
Cover Gutter: Cover gutter only applies to the cover of hardcover books. The gutter width will be 8mm - 10mm besides the spine on both sides (back cover and front cover).
Page Spread: Page spread must be designed in single page reading spread (pg1, pg2, pg3 etc). The only acceptance for full spread (pg1&pg2, pg3&pg4, pg5&pg6 etc) will be for board books with layflat finishing.
Cover & Dust Jacket: Submit the cover artwork or dust jacket artwork separately (if there is dust jacket for the book). Front cover, spine and back cover compiled into 1 page. Contact us for exact measurement and templates according to your book size and spine thickness. Please contact us if you require assistance with file requirements.
Text Safe Area: To avoid having text cut off during trimming, leave about 1/4" (0.25 inch) to 1/2" (0.5 inch) away from the edge of your document.
Tolerance: Make sure to give the book design a tolerance of at least 2 mm for trimming. Foiling allowance will be 1 mm.
Font: All fonts must be embedded or converted to path (create outlines).
Converting to PDF: When converting to press quality PDF from a typical multi-page layout software such as Adobe Indesign, ensure the following applies to the Export settings:
- Do not downsample the resolution of the file (download instructions "compress.pdf" )
- Leave 1/8 inch (3 mm) or 1/4 inch (6.25 mm) for marks & bleeds (download instructions "mark_and_bleed.pdf" )
- Color setting only in process color format (download instructions "change_color_to_cmyk.pdf" )
- Do not include any ICC profile (download instructions "do not_include_ICC.pdf" )
BEFORE SUBMITTING YOUR FILES PLEASE REVIEW THE FOLLOWING FILE SPECIFICATIONS:
- Bleed: A bleed is an extension of your background color or image going beyond the intended trim size of your piece. Please make sure your artwork has at least 1/8 inch (3 mm) margin of bleed. This ensures that the color or image continues to the edge of your piece. Please build your press-ready digital files by adding 1/8 inch or 1/4 inch all around dimension for all products. If your artwork has no bleeds, no bleed margin is required, leave it as the final trim size.
- Colors: All colors in your document must be CMYK. If you use spot colors in your design please convert them to cmyk before saving. If your job requires pantone color (ie: 4 + 1 or 4 + 2 jobs), save the document in CMYK plus the spot color(s). If you have difficulty converting from RGB to CMYK, let us know and we will process the conversion, however exact color match is not guaranteed.
- PDF - All fonts should be embedded in PDF files or created outlines.
- EPS - All fonts should be converted to paths or curves in EPS files.
- PSD - All layers must be flattened.
- Image Quality: Photos or scans should always be saved as CMYK. All scanned images should be of a professional standard. Images need to be saved at an appropriate resolution of 300 dpi or above for continuous tone reproduction (photos and/or illustrations).
- Text Safe Area: To avoid having text cut off during trimming, make sure that no text is within 1/4" (0.25 inch) from the edge of your document.
- Overprint: Do not enable the "overprint fill" feature. The feature will cause unexpected results during printing. We are not responsible for any unexpected outcomes when this feature is enabled.
