Step 3: Check Your Print  Margins

Although Rapido Books make every effort to adhere to your specifications, our printers have a minor variation factor of 0-1 mm.

Our Suggestions:

– Keep a safe zone of 5 mm or 1/4 inch text-free to prevent “bleeding” (having text cut off);
– If you want one or more images up to the cut, please include a bottom margin to avoid a lost white border on the edge of your page. The bleed must be at least 3 mm or 1/8 inch.
