However, in most of these instances, it makes more sense to create a PDF le, a device-independent PostScript le, or—for the adventurous—a device-dependent PostScript le using In-RIP separations, especially if you are using trapping (trapping is not supported in CMYK composite output). Choosing In-RIP Separations from the Color pop-up menu instructs InDesign to create a special type of composite CMYK le that will only print properly on a PostScript 3 output device and some newer PostScript Level 2 devices. To tell InDesign to send the composite color information to the printer without changing it, choose Composite Leave Unchanged. If you do this, you will not be able to use the Simulate Overprint option. You can also tell InDesign to separate each of your pages into four plates (or more, in the case of spot colors) by choosing Separations from the Color pop-up menu. If you select the Separations or In-RIP Separations option, InDesign activates the Inks list and its associated controls (the Flip, Frequency, Angle, Trapping settings, and so on). One problem with printing proofs on a desktop laser printer is that it’s sometimes dicult to read colored text because it appears as a tint. Similarly, when you want to fax a black-and-white version of your document, screened text becomes almost unreadable. When you turn on the Text as Black check box, InDesign ensures all your text appears as solid black—except for text that is already set to solid white, Paper color, or None.

Select this option when you want to leave trap- ping up to the RIP in your printer or imagesetter. is feature, which makes us rather nervous, only works on PostScript 3 and some PostScript Level 2 printers. We cover trapping in a bit more detail in Chapter 10, “Color.” InDesign can mirror pages at print time if you choose Horizontal, Vertical, or Horizontal & Vertical from the Flip pop-up menu. Flip- ping an image is used for creating either wrong- or right-reading lm from imagesetters, or lm with emulsion side up or down. is is oen handled in the imagesetter or platesetter, so be careful before you go changing this setting. e same thing goes for the Negative check box, which inverts the entire page so that everything that is set to 100-percent black becomes zero-percent black (eectively white). Never make assumptions about what your output provider wants; what you think will help might actually hinder (and cost you money in the long run). What halone screen frequency (in lines per inch) and screen angle do you want to use to print your publication? If you selected Com- posite Gray in the Color pop-up menu, you can choose either the printer’s default (which is dened by the PPD you selected) or you can choose Custom and then enter your own values in the Frequency and Angle elds. When you’re printing separations, you’ll see more choices on the Screening pop-up menu, and the values shown in the Frequency and Angle elds change as you select inks in the Inks list. Where the heck are these choices and values coming from? ey’re coming from the PPD. Every PPD contains a list of screen frequencies and screen angles optimized to avoid moiré patterns on the specic PostScript device described by the PPD.

On PostScript Level 1 devices, the screen angle and screen fre- quency you’d get would sometimes fail to match the frequency and angle you specied. is oen resulted in serious output problems and severe moiré patterns. PPDs list combinations of screen angles known to be safe for a given printer at a screen frequency and angle. While the need for these optimized screen angles has diminished somewhat with newer versions of PostScript, we strongly advise you to stick with them when you’re printing separations. To override the optimized screen settings for an ink, select the ink in the Inks list and then enter new values in the Frequency and Angle elds. Again, we don’t recommend this, but you might have a very good reason for doing so that we simply haven’t thought of yet (like perhaps you’ve lost your mind). e optimized screen angles only cover the process inks, however. When your publication includes spot inks, InDesign sets the screen angle of every spot ink to 45 degrees. For spot-color work—especially where you’re overlaying tints of two spot colors or using duotones from Photoshop based on two spot inks—you need to specify the screen angles appropriately. Here’s how to set them.  If the spot inks never interact, set the screen angle for the inks to 45 degrees (because a 45-degree halone screen is the least obvi- ous to the eye).  If you’re creating lots of two-ink tint builds, or using duotones, you have a few choices, and two (somewhat contradictory) goals. You want both colors to print as close as possible to 45 degrees (especially the dominant, or darker, color), and you want as much separation between the angles as possible (the greater the separation between angles—45 is the maximum possible—the less patterning will be visible where the screens interact). Table 11-2 lists some options.  If you’re printing with two spot inks and the spot colors don’t overprint any process inks, use the default screen angles for Magenta and Cyan from the optimized screen you’ve selected. Note that even if you set specic screen frequencies and angles for every color, you may not get what you ask for. Most imagesetters and platesetters these days strip out all screening settings and replace them with their own unless you (or your output provider) turns o this process. We’ve been caught by this several times, when we’ve Real_World_Adobe_InDesign_CS4b.pdf 663Real_World_Adobe_InDesign_CS4b.pdf 663 08/04/2009 05:56:00 p.m.08/04/2009 05:56:00 p.m.  .   chosen low-frequency screens in order to create a special eect, only to nd our instructions ignored and the normal 133 lpi halone appear. Very annoying. When you select the Separations option, InDesign activates the Inks list. In this list, you’ll see at least the four process inks (yes, they’ll appear even if you aren’t using process colors in your publication), plus any spot inks you’ve dened. When you select an ink in the Inks list, InDesign displays the halone screen properties for that ink in the Frequency and Angle elds (see “Screening,” above). To tell InDesign not to print an ink, click the printer icon to the le of the ink name in the Inks list. You can also turn on or o all the inks by Option/Alt-clicking. Don’t worry about inks that aren’t used in your publication—InDesign will not generate a blank separation for them. If, for example, your publication uses only black ink and a spot ink, InDesign will not create separations for Cyan, Magenta, and Yellow, even though those inks appear in the Inks list. As we discussed in Chapter 10, “Color,” you can set various objects to overprint using the Attributes panel. However, most composite printers (like laser printers and inkjets) don’t support overprinting. Fortunately, you can simulate overprinting on these output devices Inks Simulate Overprint Subordinate: Dominant: Notes: 15 45 Traditional. Only a 30-degree separation, but neither angle is very obvious on its own. 0 45 Avoids patterning.

We cover the Ink Manager in Chap- ter 10, “Color.” Graphics e options in the Graphics pane control the way that InDesign prints the fonts and graphics in your publication (see Figure 11-6). e Send Data pop-up menu aects what InDesign does with bitmaps in TIFF, JPEG, and other explicitly bitmapped le formats. It has no eect on images inside imported EPS or PDF graphics. Do you want to print that 30-megabyte color scan every time you proof a document on your laser printer? Probably not. e Send Data pop-up menu gives you four options to control what InDesign does with images when you print: All, Optimized Subsampling, Proxy, and None, each of which is described below. All. Use this option when you want InDesign to send all of the image data from the image le to the printer. We recommend that you always use this option when printing the nal copies of your pages. Optimized Subsampling. is option tells InDesign to only send as much information from the image as is necessary to produce the best quality on the given output device using the current settings. It reduces the amount of data that has to be passed over the network and imaged by the printer. It can speed up printing immensely. How InDesign pares down the data depends on whether the image is color/grayscale or black and white.  Color/Grayscale images. As we mentioned in Chapter 7, “Importing and Exporting,” there’s no reason for the resolution of grayscale and color images (in pixels per inch) to exceed two times the halone screen frequency (in lines per inch).

If you’ve set up a 75-line screen (for instance), InDesign won’t send more than 150 dots per inch of image resolution. Note that InDesign does not change the resolution of the images in your publication—it just reduces the amount of data that’s sent to the printer.  Black-and-white (bi-level) images. When you’re printing bi-level, black-and-white images, and have selected Optimized Subsampling from the Send Data pop-up menu, InDesign matches the images it sends to the resolution of the output device. So if you’ve got a 600-pixels-per-inch black-and-white TIFF, and you’re printing on a 300-dpi laser printer, InDesign reduces the resolution of the image to 300 pixels per inch before sending it to the printer. For those who really want to know, InDesign gets the printer’s resolution from the DefaultResolu- tion keyword in the PPD. e real value of the Optimized setting lies in printing laser proof copies of jobs that are destined for high-resolution (hence high half- tone screen frequency) output. If you’re producing a document that will be printed with a 133-lpi screen, for instance, you may be work- ing with images that have resolutions of 250 or even 300 ppi. But for proong on a 600-dpi laser printer (which has a 85-lpi default screen frequency), you only need 106 dpi—maximum. By subsampling to this lower resolution, InDesign is sending less than one h of the information over the wire. Obviously, this can save you a lot of time.  - e Graphics Panel of the Print Dialog Box Real_World_Adobe_InDesign_CS4b.pdf 666Real_World_Adobe_InDesign_CS4b.pdf 666 08/04/2009 05:56:00 p.m.08/04/2009 05:56:00 p.m.       With high-resolution line art, InDesign might send only a sixteenth of the data. Printing an image using the Optimized Subsampling option pro- duces a more detailed printed image than using the Low Resolution option, but doesn’t take as long to print or transmit as would the full- resolution version of the image. While Optimized Subsampling might sound like the universal cure for perfect (speedy, high quality) printing, it isn’t. Subsampling, by its nature, blurs and distorts images, especially in areas of high contrast. erefore, we think you should use this option for proof printing, but not for printing the nal copies of your pages. Proxy. Choose Proxy from the Send Data pop-up menu to have InDesign send only the low-resolution preview images it displays on your screen to the printer. Again, this is an option to use when you’re printing proof copies of your pages, not for nal output. None. When you choose this option, InDesign prints all of the imported graphics in your publication as boxes with Xs through them. As you’d expect, this makes it print faster. Proof printing is great when you’re copy-editing the text of a publication—why wait for the graphics to print? Note that you can speed things up a bit, without completely elimi- nating the graphics, by using the Proxy or Optimized Subsampling option on the Send Data pop-up menu. Also, note that you can turn o the printing of a particular type of imported graphic using the Omit EPS/PDF/Bitmap Images options in the Advanced pane of the Print dialog box. One of the best ways to speed up InDesign’s printing is to manage downloaded fonts sensibly. You can save many hours over the course of a day, week, month, or year by downloading fonts to your printer in advance, and by understanding the way that InDesign handles font downloading. e basic concept is pretty simple: Fonts can be either “resident” (which means that they’re stored in your printer’s memory or on a hard drive attached to the printer) or “downloadable” (which means they’re stored somewhere on your system or network). When you print, InDesign checks the printer PPD to see if the fonts are available on the selected printer. If the font is available, InDesign sends a reference to the font, but does not send the font itself, which means that the text will be printed in the font available on the printer. Font Downloading Real_World_Adobe_InDesign_CS4b.pdf 667Real_World_Adobe_InDesign_CS4b.pdf 667 08/04/2009 05:56:01 p.m.08/04/2009 05:56:01 p.m.  .   What happens when a font is not available in the printer’s memory or on its hard drive? at depends on the option you’ve selected in the Fonts section of the Graphics pane of the Print dialog box. When you choose the None option, you’re directing InDesign to refrain from including any fonts in the PostScript it’s sending to the printer (or to disk). If text in your publication has been format- ted using fonts that are not resident on the printer, that text will be printed using the printer’s default font (usually Courier). When you choose the Complete option, InDesign checks the state of the Download PPD Fonts option. If this option is on, InDesign sends all of the fonts used in the publication to the printer’s memory. If the option is turned o, InDesign downloads all of the fonts used in the publication that are not listed in the PPD (PPDs contain lists of fonts available on a given make and model printer, plus any you’ve added by editing the PPD). InDesign downloads the fonts once for each page that’s printed. As you’d expect, this increases the amount of time it takes to send the job to your printer. To decrease the amount of your printer’s memory that’s taken up by downloaded fonts, or to decrease the amount of time it takes InDesign to send the fonts to your printer, choose the Subset option. When you do this, InDesign sends only those characters required to print the publication. is can speed up printing tremendously. At the same time, subsetting fonts can cause problems with some printers. If you nd that you are losing characters, that the wrong characters print, or that your printer generates a PostScript error when you’re trying to print using the Subset option, use one of the other options. If you’re printing a le to disk as PostScript for deliv- ery to a service bureau or to create a PDF using Acrobat Distiller, do not use the Subset option. Adobe would love it if everyone had PostScript 3 or PDF print engine devices. Not only would they make money from licensing fees, but their soware could also take advantage of all the cool features in PostScript 3 RIPs. However, currently many people only have PostScript Level 2 devices. (Please don’t ask us why “PostScript 3” omits the “Level” moniker. We can only assume that Adobe’s mar- keting strategists have their reasons.) In most cases, InDesign reads the PostScript version from the PPD, so you don’t have to think about this. However, if you’re making a device-independent PostScript le you will need to choose Level 2 or Level 3. (Here Adobe does use “Level.”) Postscript Level Real_World_Adobe_InDesign_CS4b.pdf 668Real_World_Adobe_InDesign_CS4b.pdf 668 08/04/2009 05:56:01 p.m.08/04/2009 05:56:01 p.m.       e Data Format feature controls how bitmapped images (like TIFF and JPEG) are sent to the printer. While sending the information in ASCII format is more reliable over some older networks, binary is almost always ne and has the benet of creating a much smaller PostScript le (the images are half the size of ASCII). We usually use binary unless we’re sending les to an output provider that we know requires ASCII. Color Management e features in the Color Management pane of the Print dialog box are complex enough that we need to cover them in a separate section. We discuss color management, including all these Print dialog box settings, in Chapter 10, “Color.” Advanced We’re not sure what makes this pane more “advanced” than the others, but it’s where you specify how InDesign should print to non- PostScript printers, images in an OPI workow, and objects that have transparency settings (see Figure 11-7). If (and only if) you’re printing to a non-PostScript/PDF device, your pages need to be rasterized (converted to a bitmap). You can control who does the conversion: If you turn on Print as Bitmap, InDesign rasterizes at a particular image resolution that you specify. If you turn it o, InDesign writes vectors to disk and lets the operating system do the conversion. In general, it works pretty well either way. When you’re printing through an OPI server, you can direct the server to replace the low-resolution images you’ve used to lay out your document with the high-resolution images you’ve stored on the server. To do this, turn o the OPI Image Replacement option and turn on the appropriate Omit for OPI check boxes. is omits the images from the PostScript output, leaving only the OPI link infor- mation in their place. Note that you can specify which types of images you want to replace with OPI comments: EPS, PDF, or Bitmap Images. When you turn on the EPS option, you’re telling InDesign not to print any EPS graphics in the le, but if PDF and Bitmap Images are still turned o then the program will include that image data at print time.

We hate to give you the runaround, but if you’re reading this hoping to learn all about how the attener works, you’re out of luck.
