Size and bleed
Prepare your file at the chosen trim size and add 3 mm bleed on every edge.
Keep text and key elements at least 5 mm inside the trim so they are not affected by cutting.
Resolution and colour
Use images of at least 300 dpi at print size.
Prepare files in CMYK; use single-colour black (K 100%) for black text.
Fonts and PDF
Embed all fonts in the PDF or convert them to outlines.
Export to PDF/X-1a or PDF/X-4 where possible; do not upload password-protected PDFs.
Book cover and spine
Prepare the cover as one spread: back cover + spine + front cover.
Spine width depends on page count and paper; our team verifies your cover size during the pre-flight check.
Page count
The page count of your interior file must match the page count in your order.
Saddle-stitched jobs need a page count that is a multiple of 4.
