Add crop marks to a PDF without losing bleed geometry
Short answer
Crop marks show where the printer should cut the sheet, but they do not replace trim and bleed boxes. Trim Proof can generate crop marks from the product geometry and then preflight the PDF/X export.
Use this page when a printer asks for crop marks or when you need a visible cut guide around a print-ready PDF.

Crop marks versus bleed
Crop marks are visible printer guides. Bleed is extra artwork beyond the trim edge. A reliable print PDF usually needs both the visible marks and the underlying PDF box geometry.
How Trim Proof places crop marks
Trim Proof derives crop marks from the selected product profile, so marks are positioned outside the final trim instead of being guessed by eye.

Common questions
Do all printers require crop marks?
No. Some printers prefer files without marks, while others ask for them. Trim Proof keeps crop marks as an explicit export setting.
Can crop marks fix missing bleed?
No. Crop marks only show where to cut. Artwork still needs to extend into the bleed area.
