InDesign CS5 Bible- P16 Chapter 31: Printing Documents l Crop Marks: These are lines at the corners of the page that tell a commercial printer where the page boundaries are, and thus to where the paper is trimmed. l Bleed Marks: These add a very thin box around your page that shows the bleed area — where you expect items to print into, even though they’re past the page boundary. (A bleed is an object that you want to be cut at the page boundary; the object needs to over- shoot that boundary in case, during printing, the page is not trimmed exactly where it should be. Normally, 0p9 (9 points), or 0.125 inches, is sufficient area for a bleed. You set the bleed area in the Marks and Bleed pane, which I cover in the next section. l Registration Marks: These are the cross-hair symbols used to ensure that the color nega- tives are properly aligned on top of each other when combined to create a color proof, and to make sure that the colors are not misregistered on the final pages when they are lined up on a printing press. l Color Bars: These print the CMYK colors and tints so that a commercial printer can quickly check during printing whether ink is under- or oversaturated — the shades could be too light or dark. The CMYK colors also help a commercial printer know which color a particular negative is for (after all, negatives are produced using transparent film with black images). l Page Information: This lists the file name and page number. If a printer has options for printer’s marks, they display in the Type popup menu, but most simply have one option: Default. You can also adjust the thickness of the printer’s marks using the Weight popup menu settings of 0.125, 0.25, and 0.5 points; the default is 0.25 points (a hairline rule). You can also control the offset of crop marks from the page corners by adjusting the Offset value; the default of 0.833 inches (6 points) usually suffices. For all of these, check with your service bureau. Because printer’s marks print outside the page, your paper size may not be large enough to print the printer’s marks. For example, if your page is 81⁄2 × 11 inches and your paper is the same size, no room is available for the printer’s marks. (The page preview subpane on the left of the Print dia- log box shows you whether printer’s marks fall outside the page’s boundaries.) Be sure that your paper size is at least 1 inch wider and taller than your page size if you use printer’s marks.NoteWhen outputting PDF files, InDesign is smart enough to automatically increase the paper size to add room forthe printer’s marks. n Bleeds and slugs The Bleed and Slug area of the Marks and Bleed pane controls how materials print past the page boundary. A bleed is used when you want a picture, color, or text to go right to the edge of the paper. Because slight variation on positioning occurs when you print because the paper moves mechani- cally through rollers and might move slightly during transit, publishers have any to-the-edge mate- rials actually print beyond the edge so that there are never any gaps. It’s essentially a safety margin. A normal bleed margin would be 0p9 (1⁄8 inch), though you can make it larger if you want. 705Part VII: Output FundamentalsTipYou can control whether all bleed margins are changed if any of them are changed by clicking the Make AllSettings the Same iconic button: If the chain icon is broken, each can be adjusted separately; if the chain iconis unbroken, changing one causes the others to change automatically. Click the button to toggle between thetwo behaviors. n A slug is an area beyond the bleed area in which you want printer’s marks to appear. The reader never sees this, but the staff at the service bureau or commercial printer does, and it helps them make sure they have the right pages, colors, and so on. As is the bleed, the slug area is trimmed off when the pages are bound into a magazine, a newspaper, or whatever. (The word slug is an old newspaper term for this identifying information, based on the lead slug once used for this purpose on old printing presses.) The purpose is to ensure that enough room exists for all the printer’s marks to appear between the bleed area and the edges of ...
