Crop marks are printed lines on publications that let someone know where to trim the document for binding or finishing purposes. The marks are black and printed along the margins of the document. You can add crop marks to any Microsoft Publisher publication via the application's "Print" menu. But before adding crop marks to your document, you must set the document's paper size to a larger setting so the crop marks can print.
Click "File" and "Open" and navigate to the Microsoft Publisher publication you want to add crop marks to, if the publication is not already open.
Click "File" and "Print." Click the page size icon for 11 by 17 paper, under the "Settings" heading, if your publication is 8.5 inches by 11 inches, to allow the crop marks to appear properly. If your publication is a size other than 8.5 inches by 11 inches, click the next-highest page size icon so the marks can appear properly on your document.
Click the down arrow next to the printer you want to print your publication on, under the "Printer" heading. Click "Advanced Output Settings" to open that dialogue box. Click the "Marks and Bleeds" tab.
Click the check box next to "Crop Marks" under the "Printer's marks" heading. Click "OK." A preview of your publication, along with crop marks, will appear in the right-hand pane of the "Print" dialogue box.
Click the "Print" icon to print the document, if desired, or click "Exit" in the lower left-hand corner to save the printer settings so the crop marks will remain on your publication.
If you are planning on sending your Publisher publication to a commercial printing service, click "File" and "Save As" to save the document, along with its crop marks, onto a removable disc -- CD, flash drive or similar medium -- then deliver the disc to the commercial printer.
