You can add a new custom mark for an existing mark or image file that you create in your choice of software. Custom mark images are also used to create duplicating marks.
Image file
Select the image file (from the drop-down menu) to use in the mark.
Rotation
Select the number of degrees to rotate the mark image clockwise around the mark anchor point.
You can duplicate (or step-and-repeat) custom marks on press sheets. Configure the duplicate pattern in the dialog box for the Custom Mark settings, or in the Marks properties pane. Enter the number of times to duplicate the custom mark vertically or horizontally on the sheet, and specify the distance to repeat the mark.
