By default, we keep a 5mm white border around your design. Do you want images or background colours to extend to the edge? Then choose borderless printing. With borderless printing, we trim the document cleanly afterward. If you do not supply bleed/bleed, we enlarge your document by 1mm all around. If you do not choose borderless printing, a 5mm white border will automatically remain visible (see example). Not all paper types and formats support borderless printing. Tip: Use the preview to check whether borderless printing is necessary. For experts: Supply 3–5 mm bleed. Crop marks are allowed. If the bleed is correct, we will not enlarge the document.
