A safe zone (or quiet border) is an area within your artwork which does not contain text, images or logos. Please include a quiet border of at least 3mm, but preferably 5mm, from the trimmed edge of your artwork. We also recommend all borders are at least 3mm, ideally 5mm wide. This avoids any part of your design appearing too close to the edge of the page and will give your job a more professional appearance.
For booklets, we recommend a 5mm (ideally 10mm) quiet border for a better finish.
