Specifying the printing bounding box in the separation
The printing bounding box is represented as a gray rectangle surrounding the artwork in 
the Separation Setup preview window. The bounding box sets the position of the crop 
marks on your separations and defines the printable boundaries of the artwork, as well as 
nonprintable boundaries such as direction lines. 
You can define the printing bounding box either by using the Object > Crop Marks > Make 
command, or by using the Separations Setup dialog box to set the bounding box at the 
artwork boundaries. You can also modify the current bounding box dimensions in the 
Separations Setup dialog box.
The numbers in the Margins text boxes show where the image lies within the page. These 
numbers measure the distance from the 0,0 point in the imageable area to the edges of 
the bounding box. The 0,0 point is in its default position at the bottom left corner of the 
page boundary.
If you select a different page size, the margin numbers change as Illustrator calculates the 
distance of the bounding box from the edge of a new page size. 
Note: The Margins numbers for a given page size (such as Letter) may vary by PPD file. This 
is because printers and imagesetters may differ in how they define the size of an 
imageable area.
To specify the printing bounding box using crop marks:
Do one of the following:
Draw a rectangle to define a customized printing bounding box, and then select the 
rectangle.
Choose Edit > Deselect All to set the printing bounding box around the artboard.
Choose Object > Crop Marks > Make. 
To define the printing bounding box boundary using the Separation Setup 
dialog box:
Do not set any crop marks in the document, or remove existing crop marks by choosing 
Objects > Crop Marks > Release. If the existing crop marks were created using a rectangle, 
delete that rectangle.
Choose File > Separation Setup. The printing bounding box is placed by default as 
tightly as possible around all the artwork.
To modify the existing printing bounding box:
In the Separation Setup dialog box, do one of the following:
Enter values in the Left, Right, Top, and Bottom margin text boxes. Press Tab to go to the 
next text box.
Drag any of the size handles in the preview.
Select Revert to cancel any changes and revert to the previous bounding box settings.
Specify another separation option, or click OK.
