You can edit the default settings for marks in the Marks palette, or selected instances of a mark placed on a layout.
You can edit properties such as the color, font, font style, and font size. When using an editable text mark, you can also modify the text that the mark displays.
You can control the separations on which a mark prints, and the print properties of the mark for each separation, allowing you to reverse marks out of solid areas on artwork, overprint on certain separations, or have the mark print in registration color on all separations of the job.
