Crop Marks

What it does

• Crop marks tell the operator where the trim line sits.
• Marks must live outside the trim and inside the sheet.
• A missing mark turns a precise cut into a visual judgement.

How to use it

1. Use registration marks as well as crop marks when more than one colour is printed.
2. Keep marks out of the bleed area so they do not print inside the finished page.
3. Check the marks after a PDF imposition, not only in the layout file.
4. If the sheet is trimmed twice, the second cut needs its own marks.

Safety notes

• Do not place marks inside the safety margin; a trim shift will print them on the page.
• Never rely on a printer to add marks after the file is sent.
