Photoshop, Illustrator, InDesign, and Acrobat 9 Pro will now be able to use the same color settings. Each application will render color the same way, so color across the applications will look consistent on screen and will print consistently. If you do not wish to implement color management, you may elect to use what is termed a safe CMYK workflow. A safe CMYK workflow ensures that CMYK color numbers are preserved all the way to the final output device, as opposed to being converted by the color management system. This workflow is beneficial if you want to incrementally adopt color management practices. For example, you can use CMYK profiles to soft-proof without risking unintended color conversions before final output. Illustrator and InDesign support a safe CMYK workflow by default; when you open or import a CMYK image with an embedded profile, the software ignores the profile and preserves the raw color numbers. If you want your Creative Suite application to adjust color numbers based on an embedded profile, change the CMYK color policy to Preserve Embedded Profiles in the Color Settings dialog box. You can easily restore the safe CMYK workflow by changing the CMYK color policy back to Preserve Numbers (Ignore Linked Profiles). You can override safe CMYK settings when you print a document or save it to PDF. However, doing so may cause colors to be rendered in different color values. For example, pure CMYK black objects may be re-separated as rich black. For more information on color management options for printing and saving PDFs, consult the Help files for each Creative Suite 4 component. For more information on color management in Adobe products, see the self-help guide, available here: http://www.adobe.com/studio/print/pdfs/CS3_color_workflows.pdf Color swatches Creative Suite 4 components can easily share color swatches by using the Adobe Swatch Exchange (ASE) format. This makes it easy to establish standard swatches for a project, regardless of the originating application. For example, to save swatches from an InDesign document, select a range of swatches in the Swatches panel, and then choose Save Swatches from the Swatches panel menu. You are prompted to name and save the swatch file, and InDesign creates a file with the file extension .ase, containing all the selected swatches. To import swatches from an Adobe Swatch Exchange file, choose Load Swatches from the Swatches panel in Photoshop, Illustrator, or InDesign, and navigate to the saved .ase file. All swatches-regardless of color mode-are imported. OpenType font format Photoshop, Illustrator, InDesign fully support the extended features of OpenType® fonts. The OpenType format offers exciting features for designers, while being compatible with a wide range of imaging devices and workflow systems. Among the features of OpenType fonts are: • Cross-platform compatibility. A file created on a PC using OpenType fonts can be opened on a Macintosh computer using the same OpenType fonts, without any text alteration or reflow. • Extended character sets, including ligatures for letter combinations other than fi, fl, ffl, and so on. These discretionary ligatures are correctly interpreted during spellcheck. (Not all OpenType fonts include discretionary ligatures.) • Special characters such as diacriticals for non-English text, swashes, and arbitrary fractions (again, not available in all OpenType fonts). In PostScript fonts, such features have traditionally required the use of separate fonts (called Expert Sets) containing the special characters. Since an OpenType font can have in excess of 65,000 characters, all of these special features can be incorporated within one font. • Unicode number identification of characters. Unicode numbering means that, if a character exists in more than one OpenType font, it exists at the same position in the font. Thus, changing the font used by text would not result in missing or incorrect characters. (Again, not all special characters exist in all OpenType fonts, and switching to an OpenType font that did not have the desired special character would result in something called a "notdef" (not defined) character, usually indicated by a rectangle, where the character should be.)

Color swatches
Creative Suite 4 components can easily share color swatches by using the Adobe Swatch
Exchange (ASE) format. °is makes it easy to establish standard swatches for a project, regard-
less of the originating application.

the Swatches panel, and then choose Save Swatches from the Swatches panel menu. You are
prompted to name and save the swatch file, and InDesign creates a file with the file extension
.ase, containing all the selected swatches.

swatches—regardless of color mode—are imported.
