Basic Limitations of Plastic Comb Binding

Maximum document thickness after binding: 38 mm
Maximum print format for binding: A3 (for the A3 format, binding is only possible on the shorter edge of the document)

Trim, Safe Zone, and Bleed

The red line indicates where the document will be trimmed. The trim cut may not always be 100% precise, which is why it is crucial to respect the safe zone (see the blue line).

The blue line highlights the safe zone, which text and other critical design elements must not cross. Anything outside the safe zone risks being trimmed or hidden inside the binding.

The pink area represents the bleed. Bleed refers to the extra area added to the final dimensions of the graphic design – specifically, an additional 2.5 mm of graphics on each side. As shown in the image, the background graphics extend past the trim line (the person's head at the top and the chair wheels at the bottom go beyond the trim to create the bleed).

Binding Position on Individual Pages

In a double-sided printed and bound document, odd-numbered pages have the binding on the left side of the layout (see our image), while even-numbered pages have it on the right side. Keep in mind where the binding will interface with your artwork and adjust your design accordingly.

If your document includes page numbering, make sure it is aligned properly with respect to the binding side.

Other Recommendations 

• The document can easily have a bleed larger than 2.5 mm
• Including crop marks is a plus, though they are not strictly required
• For more details, please check out Basic principles of graphics preparation for print
• We can print and bind your document even without a bleed or safe zone. In that case, the final document will have white borders (the artwork will not extend to the edge of the paper)
