Crop Marks
Crop marks are used for alignment when cutting printed material on the cutting machine. Having the
machine remember the positions of the crop marks printed together with the image makes it possible to
correct cutting positions.
When to Use 4 Crop Marks vs 3 Crop Marks
In most cases you should use 4 crop marks. If you use 3 crop marks, it is not possible to use Tool Mode.
