Illustrator CS adds quite a few high-level features to its already extensive list of abilities.
Scribble Effect: One new feature is Scribble Effect, which is useful for making vector artwork that looks hand-drawn. The feature adds texture to your designs. You can control how far the scribble appears outside the lines of the original shape, and you can use these irregular shapes as image masks. Blending two scribbled shapes into a SWF file can also cause jumpy animation.
Type Enhancements: Illustrator CS borrows from InDesign and adds many improvements to its type capabilities, including a redesigned text engine. Illustrator now has character and paragraph styles, which help you retain consistent formatting and save time by applying a series of attributes to characters and words with a click of the mouse.
Illustrator CS now has advanced support for OpenType fonts and includes more than 100 such fonts. Styles can use OpenType font options such as ordinals, fractions, and discretionary ligatures, and the new Glyphs palette provides easy access to all of a font's glyphs.
Two new features help you reduce the time it takes to manually kern type. Optical Kerning analyzes words, lines, or paragraphs to determine the ideal spacing between characters of different fonts and sizes. Optical Margin Alignment shifts punctuation such as quotation marks and hyphens at the beginnings and endings of lines to make them look more even.
Better PDF Support: Illustrator CS supports Acrobat 6 and the Adobe PDF 1.5 format. It also supports layers, printer's marks, and bleeds, and it provides extensive security (such as password, printing, and copying protections) for PDF files. To save time and ensure consistency, you can now save your PDF export settings as presets, and Illustrator CS includes three: Illustrator PDF, Press PDF, and Acrobat 6 Layered PDF.
Tight Office Integration: Adobe has added a new Save For Microsoft Office command to Illustrator--useful when you want to use an Illustrator file in PowerPoint, Word, or Excel. --JONATHAN SEFF
