SPECIFYING PAGE MARKINGS

In the Export Adobe PDF or Print dialog, you can choose to have printer's marks print on your documents (see Figure 31.13):

• Crop Marks: Show the page edge at the top, bottom, left, and right of the document. Crop marks can help you ensure that items are falling exactly where you want them compared to the page edge.

• Bleed Marks: Print marks a specific distance from the crop marks, based on what you enter in the Document Setup dialog. Certain printers may have specific bleed measurements they want you to set up. Bleeds marks show if the items that you want to bleed off the page have been extended far enough past the edge of the page.

• Registration Marks: Line up documents printed as color separations.

• Color Bars: Test the density of CMYK inks, including tints of gray. These bars are used by printers.

• Page Information: Print the filename, page number, current date and time, and separation name in the lower-left corner of each sheet.
