Every print file has three invisible boundaries stacked on top of each other, and mixing them up is the fastest way to get a job rejected — or worse, printed with a white sliver down one edge.
This is the final size of your printed piece — the line the cutting blade actually follows. Whatever sits exactly on the trim line is what your customer will see at the very edge of the finished product.
Cutting isn't perfectly precise at scale. A guillotine cutting five hundred sheets at once can shift by a millimetre or two. Bleed is extra artwork — typically 3mm (0.125in) — extending past the trim line in every direction, so any tiny shift in cutting still lands on colour, not on white paper.
The opposite problem: important text or logos placed too close to the trim line risk being cut off if the blade shifts the other way. Keep anything critical — text, logos, contact details — at least 3–5mm inside the trim line, inside what's called the safe zone.
Background colours and images should extend into the bleed. Text and logos should stay inside the safe zone. Only decorative elements should ever touch the trim line exactly.
Every template in our printing software is pre-built with the correct bleed and safe zone for its product type, so this step is handled automatically if you design from a template rather than a blank canvas.
