What are crop marks in graphic design

Definition of crop marks in graphic design

Crop marks, also known as trim marks or registration marks, are thin lines or indicators printed in the margins of a document to guide the trimming or cutting process after printing. They indicate where the paper should be trimmed to achieve the final size of the printed piece.

Usage

Crop marks are essential in print design to ensure accurate trimming and to prevent any unwanted white edges or borders on the final printed piece. They provide clear guidelines for printers and finishers to cut along, ensuring that the printed material is neatly trimmed to the intended size.
