Exporting a document or book to Adobe PDF is as simple as using the default High Quality Print settings, or as customized as you need it to be to suit your task. The PDF export settings you specify are saved with the application, and will apply to every new InDesign document or book you export to PDF until you change them again. To quickly apply custom settings to PDF files, you can use presets.
You can export a document, a book, or selected documents in a book as a single PDF file. You can also copy content from your InDesign layout to the Clipboard, and automatically create an Adobe PDF file of that content. (This is useful for pasting a PDF file into another application, such as Adobe Illustrator.)
When you export an InDesign file to PDF, you can preserve navigation elements such as table of contents and index entries, and interactivity features such as hyperlinks, bookmarks, media clips, and buttons. You also have the option of exporting hidden layers, nonprinting layers, and nonprinting objects to PDF. If you’re exporting a book, you can merge identically named layers by using the Book panel.
When you export a book to PDF, you can show and hide InDesign layers in the PDF document. To avoid duplication of layer names in the PDF, you can merge the layers on export.
If the Merge Identically Named Layers On Export option is selected, layer names appear under the same book name in Acrobat or Reader. If this option is not selected, layer names appear separately under each document name.
To create a PDF of the entire book, click in a blank area of the Book panel to deselect any selected documents, and choose Export Book To PDF in the Book panel menu.
To create a PDF of documents within a book, select the document or documents in the Book panel, and choose Export Selected Documents To PDF in the Book panel menu.
