Short right-angled lines at each corner, showing where a sheet is to be trimmed.
Also known as: Trim mark, Cut mark, Corner mark
Crop marks are short lines set just outside each corner of a page, showing the guillotine where to cut. They are drawn as two lines meeting at a right angle without touching the corner itself, so the cut can be made along their extension without the mark itself being printed inside the finished piece. Where a design runs off the edge, a second set of marks shows the bleed — the extra material trimmed away — and confusing the two is the commonest cause of a white sliver at a page edge.

Is not the same as a bleed mark. Bleed is the extra material a design carries beyond the trim so that a slight cutting error leaves no white edge; confusing the two lines is the commonest cause of a white sliver down the side of a printed page.

Two short straight lines meeting at a right angle just beyond a corner, with a small gap between their meeting point and the corner itself.
Both are printed outside the trimmed area.
