ptg Chapter 18 Managing Color from Monitor to Print 429 Working with Rendering Intents Work with Rendering Intents Open a document. Click the View menu, point to Proof Setup, and then click Custom. Click the Rendering Intent list arrow, and then select from the following options: ◆ Perceptual. Preserves the natural colors of an image, as viewed by the human eye, sometimes at the expense of the true color values. Good for photographic images. ◆ Saturation. Produces vivid colors in an image, without paying attention to the original color values of the image. Good for business graphics, and charts where you want the colors to pop. ◆ Relative Colorimetric. Shifts the color space of the document to that of the maximum highlight values of the destination. Useful for photographic images, and preserves more of the original color than Perceptual. ◆ Absolute Colorimetric. Clips any colors in the destination image that do not fall into the color gamut of the destination. Use to proof images sent to devices such as 4-color presses. Click OK. 4 3 2 1 Rendering Intents define how the selected color profile is converted from one color space into another. When you choose a rendering intent you are specifying how the colors should be displayed, even at the expense of the original gamut (range of colors) within the active docu- ment. The rendering intent you choose depends on which colors are critical in an image and on your preference of what the overall color appearance of an image should be. Many times the intent of the image's color gamut is different than how the original image was shot. 1 4 3 Image with a Web Coated profile. From the Library of Wow! eBook ptg 430 Chapter 18 In the language of the print world, a soft proof is viewed on a monitor, and a hard proof (sometimes referred to as a match print) is viewed on a piece of paper, typically printed on a device such as an inkjet or laser printer, that is less expensive than producing a hard proof from a print- ing press. In the last few years, many inkjet printers now have the reso- lution necessary to produce inexpensive prints that can be used as hard proofs, which previously had to be printed on high-end printing presses, or expensive high-resolution laser printers. A hard proof gives you something you can hold in your hands, and is not only useful for viewing colors, but even evaluating the layout. Since a monitor typically displays a document at a different size than your printed document dimensions, you now have an exact size to match to your final document and review before going ahead with the final printing. When you select a printer in the Preview Print dialog box, Photoshop automatically lists the profiles installed for that printer at the top of the profile list (New!). If a printer specific profile is available, Photoshop automatically selects it (New!) for the best results, however you can change it as desired.

They may also look very different when printed on your desktop printer or when printed on a professional printing press. If your work in Photoshop requires you to produce consistent color across different devices, managing color should be an essential part of your workflow. Photoshop gives you a group of predefined color man- agement systems, which are designed to help you produce consistent color. These management systems are recognized by other Adobe products, and by most professional printing services. In most cases, the predefined sets are all you will need to manage color workflow or, as you become more adept at managing color, they can be used as a basis for creating your own customized sets. The power of color manage- ment lies in its ability to produce consistent colors with a system that reconciles differences between the color spaces of each device. Working with Color Management Work with Color Management Open Photoshop (it is not necessary to open a document). Click the Edit menu, and then click Color Settings. Click the Settings list arrow, and then select from the available options: ◆ Custom. Create your own customized set (requires a good knowledge of color management and color theory). ◆ Monitor Color. For creating content for video and onscreen presentations. ◆ North America General Purpose 2 (default). For creating consistent workflow with Adobe applications used in North America. ◆ North America Prepress 2. The defaults for common prepress operations in the U.S. ◆ North America Web/Internet. Manages color-space content for documents published on the Web. ◆ More Settings.

Create your own customized color sets using the following options: ◆ Working Spaces: Defines the working color profiles for each color model. Working Spaces can be used for images that were not previously color- managed, or for newly created color-managed documents. ◆ Color Management Policies: Defines how the colors in a specific color model are managed. You can choose to embed or convert the selected profile, or to ignore it. ◆ Conversion Options: Defines exactly how you want the conversion process handled using a color-defined Engine, and color conversion Intent. You can adjust for black point when converting color spaces, dither color channel information when converting between color spaces and compensate for Scene-referred Profiles. ◆ Advanced Controls: Desaturate Monitor Colors gives you the ability to control the viewing of a color space on different monitors; however, if activated, images will print differently than viewed. You can also decide what Gamma level is used when blending RGB values. To save col or sett ings as a pre se t, click Save, and then save the file in the default location.

Click OK. 7 6 5 4 4 6 5 7 Synchronizing Color Settings Across CS5 When you set up color management using Adobe Bridge, color set- tings are automatically synchronized across all Adobe Creative Suite programs, which makes sure colors look consistent. It's a good idea to synchronize color settings before you work on new or existing documents, so the color settings match from the start. To work with color settings, click the Edit menu, click Creative Suite Color Settings, select a color setting from the list, and then click Apply. If the default settings don't suit your needs, select the Show Expanded List of Color Settings Files option to view additional settings. To install custom color settings, click Show Saved Color Settings Files. For Your Information From the Library of Wow! eBook ptg 434 Chapter 18 When you work on a color document, you're viewing the image using your own computer, with a specific version of Photoshop, and a unique monitor calibration. What you need is a way to preserve the visual set- tings of the document. In other words, you want someone else to see what you see. The ICC (International Color Consortium) color profiles provide a universal way of saving (called tagging or embedding) a mathematical definition of a particular color space, and gives you a reasonable certainty that the document will display correctly on other devices. Although there are several file modes that accept ICC profiles, the two most common are RGB and CMYK. Embedding ICC Color Profiles Embed ICC Color Profiles Open a document. Click the View menu, point to Proof Setup, and then click Custom. Click the Device To Simulate list arrow, and then select a color profile for the image. Click OK.
