#95. Exporting Documents as PDF
At many publishing sites, publications in progress are exported as PDF documents for electronic markup and review, and finished publications are exported as PDF for final, high-resolution output. When it's time to export an InDesign layout as a PDF file, you have many options for controlling the size and many other characteristics of the file. The choices you make when you export a PDF file depend on how the PDF will be used. For example, if you want to distribute a PDF via email to colleagues or clients for electronic review and markup using Acrobat or Reader, you should save a compact, low-resolution PDF that's ideal for electronic distribution and review but not appropriate for high-resolution output. If you intend to send a PDF file to a print service provider for high-resolution output, you should save a high-resolution file.
If you've used InDesign's book feature to combine several layouts into a book, you can export all documents or selected documents as PDF. (For more about books, see #85.) To export all documents in a book as a single PDF file, open the book file, click a blank area in the Book palette. and then choose Export Book to PDF. To export some but not all documents, select the documents you want to export in the Book palette, and then choose Export Selected Documents to PDF. The rest of the process is the same as exporting a document as PDF.
To export a layout as PDF:
Choose File > Export.
In the Export dialog box, enter a name for the PDF file and choose the folder in which the file will be saved.
Choose Adobe PDF from the Format menu (Mac OS) or Save as Type menu (Windows), and then click Save.
At this point, you can simply choose a PDF preset in the Adobe PDF Preset menu, and then click Export, or you can choose a preset, customize the settings in the various panels of the Export Adobe PDF dialog box (Figure 95), and then click Export. (For more about using PDF presets, see #96.) If you change a setting, "(modified)" is displayed to the right of the preset selected in the Adobe PDF Preset menu.
Figure 95. When you export an InDesign document as PDF, the settings you make in the panels of the Export Adobe PDF dialog box determine the size and characteristics of the PDF document.
When you make changes in the Export Adobe PDF dialog box. they're saved with the application and used the next time you export a layout as PDF.
Exporting Interactive, Multimedia PDFs
When you export a PDF document that contains bookmarks. hyperlinks, buttons, and multimedia files (pictures and sounds), make sure you check Bookmarks, Hyperlinks, and Interactive Elements in the General panel of the Export Adobe PDF dialog box.
Copying Objects as PDF
You can also use PDF to copy objects from InDesign to PDF-aware programs like Illustrator and Photoshop. For example, if you've created a graphic in InDesign and you want to use it in a Photoshop image, you can copy the object in InDesign and then paste it into Photoshop. If you check Copy PDF to Clipboard in the File Handling panel of the InDesign Preferences dialog box. PDF data is copied to the clipboard when you choose Edit > Copy or Edit > Cut. To use copied objects in a PDF-aware program. switch to that program, and then choose Edit > Paste.
