ptg 404 Chapter 25 In this next step in color management, you’ll create a custom proof setting for your specic inkjet printer and paper, and use it to view a soft proof, or onscreen simulation, of your print output. Although the soft proof won’t be perfectly accurate, it will give you a rough idea of how your colors will look (with- out costing you a penny). To proof a document as an inkjet print onscreen: 1. From the View > Proof Setup submenu, choose Custom. e Customize Proof Condition dialog opens. In the next steps, you will choose custom proong settings for your output device. A 2. Check Preview, then from the Device to Simulate menu, choose the correct color prole for your inkjet printer and paper (the prole you either downloaded from a manufacturer’s website or installed with your printer driver le). 3. Uncheck Preserve RGB Numbers, if available. Photoshop will simulate how the colors will look when converted to the output prole. is option is available only if the color mode of the output prole that you chose from the Device to Simulate menu matches that of the current le (e.g., if your image is in RGB Color mode and you chose an RGB device as the Device to Simulate). 4. Choose a Rendering Intent to control how colors will change as the image is shifted from one pro- le to another (see the sidebar on the next page). We recommend choosing either Perceptual or Relative Colorimetric. You can evaluate a couple of options via the preview and by making some test prints. Check Black Point Compensation to allow adjustments to be made for dierences in black points among dierent color spaces. With this option chosen, the full dynamic range of the image color space is mapped to the full dynamic range of the color space for the output device (the printer). With this option o, black areas in the image may display or print as grays. We recommend checking this option for inkjet printing. 5. Optional: For Display Options (On-Screen), check Simulate Paper Color to preview the white of the printing paper as dened in the printer prole; or if you’re going to print the le on uncoated paper, check Simulate Black Ink to preview the full range of black values that the printer can produce. 6. To save your custom proof setup, click Save, enter a name, keep the .psf extension, keep the location as the default Proong folder, then click Save. 7. Click OK. Saved proof setups are available on the Custom Proof Condition menu in this dialog and at the bottom of the View > Proof Setup submenu. View > Proof Colors will be checked automatically, so you can see the soft proof. And for the moment, the Device to Simulate prole is listed in the tab of the current document. Remember, the Proof Setup options control only how Photoshop simulates colors onscreen. Colors in the actual le won’t be converted to the chosen prole until you convert the docu- ment to a dierent color mode (such as from RGB to CMYK) or send it to an inkjet printer. Proofing colors onscreen A To generate a soft proof of our document, in the Customize Proof Condition dialog, we’ve chosen the prole for our Canon Pixma inkjet printer as the Device to Simulate. ptg Print 405 Choosing a Proof Setup preset will cause Photoshop to soft-proof (simulate) the colors in your RGB le onscreen as if it were printed using CMYK inks or displayed online on a Windows or older Macintosh display. To proof colors onscreen for commercial printing or online output: 1. From the View > Proof Setup submenu, choose the preset for the output display type that you want Photoshop to simulate: Working CMYK to simulate colors for the commercial press that is currently chosen on the CMYK menu under Working Spaces in the Edit > Color Settings dialog in Photoshop. Legacy Macintosh RGB (Gamma 1.8) or Internet Standard RGB (sRGB) ★ to simulate colors for online output using the legacy Mac gamma (1.8) or Windows gamma (2.2) as the proong space. Monitor RGB to simulate colors using the custom display prole for your monitor. 2. View > Proof Colors will be checked automati- cally. To turn o soft proong at any time, simply uncheck it (Ctrl-Y/ Cmd-Y). Printing a file on an inkjet printer In this section, we will show you how to output your le to an inkjet printer and obtain a quality color print that closely matches the document you have been viewing onscreen. You will complete the color management setup that you started in Chapter 1 by choosing settings in the Print dialog. We have divided the steps for using this dialog into three parts: choosing settings for the printer driver, choosing settings in the Print dialog for Photoshop, and nally, turning o color man- agement for the printer and printing the le in Windows or the Mac OS. CHOOSING A RENDERING INTENT ➤ Perceptual changes colors in a way that seems natural to the human eye, while attempting to pre- serve the appearance of the overall image. It’s a good choice for continuous-tone images. ➤ Saturation changes colors with the intent of preserving vivid colors, but in so doing compromises color fi delity. Nevertheless, it is a good choice for charts and graphics, which normally contain fewer colors than continuous-tone images. ➤ Absolute Colorimetric maintains the color accuracy only of colors that fall within the destination color gamut (i.e., the color range of your printer) but in so doing sacrifi ces the accuracy of colors that aren’t within that gamut. ➤ Relative Colorimetric, the default intent for all the Adobe predefi ned settings in the Color Settings dialog, compares the white, or highlight, of your document’s color space to the white of the destina- tion color space (the white of the paper, in the case of print output), shifting colors where needed. This is the best rendering intent choice for documents in which most of the colors fall within the color range of the destination gamut, because it preserves most of the original colors. Note: Consult your printer manual when choosing a rendering intent. For example, some inkjet printers favor Perceptual over Relative Colorimetric. Continued on the following page ptg 406 Chapter 25 4. e menu names vary with the chosen printer model, so we will refer to them generically: In Windows, in the Main (or other) tab, choose the best-quality option for photo printing. For the paper options, choose the source for your paper, the specic type of paper to be used, and the paper size ( A , next page). In the Mac OS, the inkjet printer you chose in step 2 will be listed on the Printer menu. Choose the desired paper size for the print (for a borderless print, pick a size that includes the word “borderless”). From the fourth menu down, choose the print quality and paper options category (e.g., Quality & Media or Print Settings). From the media or paper type menu, choose the type of paper you will be using ( B , next page), and from another menu, choose a print quality option ( C , next page). 5. Click Save to close the [Printer Name] Properties/OS-level Print dialog and return to the Print dialog for Photoshop. Now you’re ready to choose print settings for Photoshop (see page 408). In Photoshop CS5, all the necessary printing options are in the Print dialog. And unlike in pre- vious versions of Photoshop, clicking the Print button sends your le directly to the printer. Upon opening the Print dialog, the rst step is to tell Photoshop what type of printer you will be using. You will also click the Print Settings button to gain access to the print dialog for your operating system, in order to specify the paper size, paper type, and other printer-specic options. To choose settings in the Print dialog for inkjet printing: ★ Part 1: Choose settings for your printer driver 1. Open the le to be printed, then choose File > Print (Ctrl-P/Cmd-P). e Print dialog opens, complete with a preview. A 2. From the Printer menu, choose the inkjet printer you’re planning to use. 3.

If you don’t see your custom installed prole there, scroll downward on the list. 6. From the Rendering Intent menu, choose the same intent that you used when you created the soft-proof setting for your inkjet printer, which most likely was either Perceptual or Relative Colorimetric (see the sidebar on page 405). ➤ You could run one test print for the Perceptual intent and one for the Relative Colorimetric intent, and see which one produces better results. 7. Check Black Point Compensation. is option preserves the darkest blacks and shadow details by mapping the full color range of the docu- ment prole to the full range of the printer prole, and is recommended when printing an RGB image. 8. Below the preview, do the following: Check Match Print Colors to display a color- managed soft proof of the image in the pre- view, based on the chosen printer and printer prole settings. Uncheck Gamut Warning. This option previews out-of-gamut colors as gray. It is necessary only when printing to a commercial CMYK printer. Check Show Paper White to have the paper color be simulated in any white areas in the preview, based on the current printer profile. 9. Before printing the image, you need to turn o color management for your printer. To do this, carefully follow the steps on page 411 for Windows or on page 412 for the Mac OS. ➤ Click Done in the Print dialog if you want to save all of your settings for the current docu- ment and close the dialog. After choosing print settings by following the steps on page 406, the next step is to choose position, scale, color management, and output options in the Print dialog for Photoshop. Part 2: Choose settings in the Print dialog ★ 1. In the Print dialog for Photoshop ( A , next page), click the portrait or landscape ori- entation button. Check Center Image to posi- tion the image in the center of the paper. Or to reposition the image on the paper, uncheck Center Image and enter new Top and Left values (note the preview); you can also check Bounding Box, if desired, then drag the bound- ing box in the preview. 2. Optional: To scale the print output slightly (not the actual image), do one of the following: Check Scale to Fit Media to t the image auto- matically on the paper size you chose in step 4 on page 406. Uncheck Scale to Fit Media, then change the Scale percentage or enter specic Height and Width values (choose a unit from the Units menu). e three values are interdependent; changing one causes the other two to change. Note: Use these features to scale the print by only a small amount (i.e., fractions of an inch or a few percentage points). If a larger scale change is needed, cancel out of the dialog, use Image > Image Size to scale the image (see pages 122–124), then resharpen it. 3. From the menu in the upper right, choose Color Management, then click Document to use the color prole that’s embedded in the image, which will be Adobe RGB (1998) if you’re continuing with the color management workow that you began in Chapter 1. 4. From the Color Handling menu, choose Photoshop Manages Colors to let Photoshop handle the color conversion. is option will ensure optimal color management. (See the sidebar on the next page.) 5. From the Printer Profile menu, choose the printer, ink, and paper prole that you have ptg Print 409 A Choose settings in the Print dialog in Photoshop. WHY WE LET PHOTOSHOP MANAGE COLORS From the Color Handling menu of the Print dialog, you can choose to let Photoshop or your printing device manage the colors. What’s the difference? ➤ If you choose Photoshop Manages Colors (the option we recommend), you will be able to select a profi le that matches the paper choice you made in the Print Settings dialog. Choose either the printer and paper profi le that you downloaded from a paper or print manufacturer’s website or a profi le that was installed with your printing device. Photoshop will adjust colors to fi t that profi le, then send the data to the printer. By using the profi le, your color-managed workfl ow is preserved, and you enable Photoshop to use its expertise to produce good color. ➤ If you choose Printer Manages Colors, the printer driver will handle the color conversion instead of Photoshop. This may limit the print quality, for two reasons. First, the printer won’t be aware of your custom paper choice and custom printer profi le. And second, color conversion will be subject to the printer’s ability to convert colors rather than the color management settings you have been using up to this point. Note that with this option chosen you can adjust the amount of each ink color the printer uses (and thereby override the default printer settings), but we don’t recommend doing so. ptg 410 Chapter 25 CHOOSING OUTPUT OPTIONS To access options for commercial printing, from the menu in the upper right corner of the File > Print dialog for Photoshop, choose Output. Some key Printing Marks options that we think you should be aware of are listed below. For other options, refer to Photoshop Help. Some of the Output options that can be produced from the Print dialog in Photoshop are shown on this printout. Label Crop marks Registration mark Description Under Printing Marks, check any of the following options: ➤ Calibration Bars prints a grayscale and/or color calibration strip outside the image area. ➤ Registration Marks prints marks that a print shop uses to align color separations. ➤ Corner Crop Marks and Center Crop Marks print short little lines that a print shop uses as guide lines when trimming the fi nal print. ➤ Description prints, outside the image area, whatever information is listed in the File > File Info dialog (in the Description fi eld in the Description tab). ➤ Labels prints the fi le name, document color mode, and current channel name on each page (outside the image area). A few of the options available in the Functions area are as follows: ➤ Include Vector Data causes the edges of any vector objects (such as type or shapes) to print at the printer resolution, not at the document reso- lution.
