Crop Marks are thin lines printed outside the finished artwork that show where a piece should be trimmed to its final size. They act as cutting guides during production to ensure consistent, accurate trimming across a print run.
Crop marks are typically used alongside bleed so printers can cut through the bleed area and deliver clean edges with no white borders. They are a standard part of print-ready files for items like cartons, labels, inserts, and marketing collateral.
