The part of an image or solid colour that extends beyond the trimmed size and is cut away. Without it, the slightest drift of the guillotine leaves a white sliver along the edge.
The printer states how much to allow, often 3 mm, and more for a hardback cover that wraps round the boards. The rule also runs the other way: text or a logo too close to the edge may be clipped, so keep a safe area inside the trim. On the proof, check against the crop marks rather than the screen.
