Crop marks are lines on the design that serve as a guide for where the image or product will be cropped. To create crop marks in Photoshop, follow the steps below:
Open your file in Photoshop
Choose File > Print
Select “Output” from the drop-down list on the pop-up menu
Check off “Corner Crop Marks”
Click “Print”
You may submit your files with crop marks that are added outside of the design itself, but please ensure that crop marks are not within the design, as we will not remove the crop marks from the design.
