| Adobe CS2 applications share core technologies an "understructure" that binds them together. Imagine that these are like the utilities under the streets of your city or town the water pipes, gas lines, electrical and network cabling, and so on on which we all depend. These technologies make the applications work together smoothly and seamlessly. They account for the interoperability, reliability, and high quality of the applications. Adobe Graphics Manager. One of the most notable features of working in the CS2 applications is the high quality of their previews and printing equally evident on a Macintosh or in Windows. The reason is that the Adobe Graphics Manager controls screen display and printing, without relying on the operating system. This also means that things appear exactly the same on either platform or between applications. This is a far cry from the days when a designer working on a Macintosh had no idea what her client was seeing on his Windows machine. The high-quality display is the default setting for all CS2 applications except InDesign. In InDesign CS2, choose View > Display Performance > High Quality Display. You can also select an object, like a graphic, and choose Object > Display Performance > High Quality Display, or use the context menu. This high-quality display also means that you can better trust what you see onscreen. Unlike in the past, where you had to print pages to see small details in placed images, the high-quality display works, even at huge magnifications. Figure 7-1.

The Adobe Color Engine provides ICC-based color-management services to all CS2 applications. If you purchased Adobe Creative Suite 2, you can control color-management settings for all applications from Adobe Bridge. Other new enhancements to the color interface for CS2 applications are discussed in Chapter 10, "Color and Color Management." We cover another color engine feature, Overprint Preview, in the "Overprinting Color and Overprint Preview" section of Chapter 16, "Preflight and Printing." Native File-Format Support. Another big benefit of Adobe Creative Suite 2 is that each application understands how to work with files created by the other applications. This isn't as simple as it sounds. In the past, working with a Photoshop file was as foreign to a page-layout program as running a submarine would be to Christopher Columbus. So it is not a small matter that InDesign places native Illustrator, Photoshop, and Adobe PDF files something that other page-layout applications can't do. Illustrator knows how to convert its files into the Photoshop format, preserving many layer, graphics, and type features. And Photoshop knows how to work with native Illustrator files. This native file-format support is one of the most important features of the CS2 applications and will be discussed throughout this book. CoolType. The CS2 applications are also known for their high-quality typography and type features because they use their own type engines and font handling, managed by a core technology called CoolType. This is what provides full support for OpenType fonts, building font menus, and the other features described in Chapter 6, "Type Magic." Transparency and the Transparency Flattener. The ability to create true transparency effects is built into Photoshop, Illustrator, and InDesign. To print transparent objects, transparency must first be flattened. Flattening can be done in Illustrator, InDesign, and Acrobat 7 Professional. Both transparency and transparency flattening are handled consistently in the CS2 applications because these processes rely on common core technologies, discussed in Chapter 11, "Transparency," and the "Controlling Transparency Flattening" section of Chapter 16, "Preflight and Printing." PDF Library and CS2 New Global PDF Settings. Adobe developed the Adobe Portable Document Format (PDF) and Adobe Acrobat. The PDF Library is the core technology built into all CS2 applications that manages the creation, rendering and display, editing, conversion, and printing capabilities of Adobe PDF. New in CS2 applications are global PDF settings that are shared between applications. See Chapter 14, "Creating and Using PDFs," for more information.
