Adobe illustrator cs4- P17454 CHAPTER 14: SAVING AND EXPORTING FILES SAVING FILES FROM ILLUSTR ATOR When you save a document from Illustrator using any of the file formats found in the Save or Save As dialog box, you are able to reopen that file and edit it as needed. When you do, all native information, by default, is preserved in the file. For example, if you save a file as an EPS document, you can reopen the EPS file in Illustrator and make edits to the file with no loss of functionality or editability. Adobe calls this round-tripping, and working in this way has many benefits. NOTE The latest If you create a file in Illustrator but you need to place it into a version of QuarkXPress QuarkXPress document, you’ll learn that you can create an EPS file.available at the time of Because an Illustrator EPS file is round-trippable, you can place the EPSthe printing of this book, file into your QuarkXPress layout, yet you can edit that same EPS file inversion 8, features the abilityto place native Illustrator files Illustrator if you need to make changes.in addition to EPS files. See As you will find out, Illustrator accomplishes this by using what engineersthe section “Print Workflows” call dual-path files. This means a single file contains two parts in it: Onelater in this chapter for moreinformation. part contains the EPS data that QuarkXPress needs; the other contains the native Illustrator information that Illustrator needs. As we explore the dif- ferent formats and their settings, this dual-path concept will become clear. The Native Illustrator (.ai) Format By default, when you choose to save a new file, the file format setting is Adobe Illustrator Document. Whenever you create documents, it’s best to save them as native Illustrator files, because they will always contain rich and editable information. NOTE When creating Up until Illustrator 8, the native file format for Illustrator was PostScript documents that you (EPS), but for a variety of reasons, with the release of Illustrator 9, Adobeplan to use as a base for other changed the native file format to use the PDF language. In fact, Adobe isfiles, you may choose to save quick to tell you that a native Illustrator file can be opened and viewed inyour file as an IllustratorTemplate (.ait).

It“Creating and Managing makes sense when you think about it, because if the native file format forDocuments.” Illustrator is using the PDF language, then placing it in InDesign is similar to placing a PDF file in InDesign. In reality, though, the native file format is a special flavor of the PDF language—a flavor that only Illustrator can understand. Certain constructs SAVING FILES FROM ILLUSTRATOR 455exist in Illustrator that do not exist in the PDF language, such as live blends,Live Paint effects, and live effects (these effects are all expanded when printedor translated to regular PDF). You can think of the native file format forIllustrator as a superset of the PDF language. If this is the case, however,how is InDesign or Acrobat able to import and display native Illustratorfiles? That’s where the dual-path concept comes in.When you save a native file, Illustrator embeds two files—a native Illustratorfile (.ai) and a standard PDF file (Figure 14.1). When you place the nativeIllustrator file into InDesign, the application sees the PDF portion and usesthat for display and printing. When you reopen the file in Illustrator, theapplication sees the native Illustrator portion and uses that for editing. In theend, everyone is happy, and you get to work with a single file.
