Add printer’s marks

Choose File > Print.

Select Marks & Bleed on the left side of the Print dialog box.

Select the kinds of printer’s marks you want to add. You can also choose between Roman and Japanese-style marks.

(Optional) If you select Trim Marks, specify the width of trim-mark lines and the offset distance between the trim marks and the artwork.

To avoid drawing printer’s marks on a bleed, be sure to enter an Offset value greater than the Bleed value.
