Applies to the Adobe InDesign plug-in version 31
The Export to EPUB workflow action exports an EPUB file from an Adobe InDesign file (.indd or .indb).
We improved and simplified Export to EPUB's user interface with the release of the Adobe InDesign plug-in version 31. To see what changed, see Introducing the updated Export to EPUB user interface.
The Export to EPUB workflow action is divided into five tabs: General, Text, Links, Metadata, and Advanced.
You can also use workflow variables to specify input fields. To insert a workflow variable, click the lightning bolt icon and choose a variable from the pop-up menu.
Use this tab to specify the input, output, InDesign Server, and page range.
|Input||The file path to the input InDesign document (.indd). Click the Choose File icon to choose the input InDesign document (.indd) or book (.indb). Alternatively, enter the file path—for example, Input/my-input.indd.|
|Output||The file path to the output e-book (.epub). Enter a name for the exported EPUB file (.epub). Alternatively, click Choose File to choose an output from the pop-up menu.
The default output is output-1.epub.
|InDesign Server||Choose the InDesign Server or Blinkenlights queue.|
|EPUB format||Choose the EPUB file format. Options include:
|Cover||Choose a cover image. Options include:
|Cover image||The file path to an external cover image. If you chose External image from the Cover pop-up menu, click Choose file to choose the cover image. Alternatively, enter the file path to the cover image—for example, Covers/images/my-image.png.|
|Content order||Choose the content order that page elements are exported. Options include:
In the majority of cases, Based on page layout is the best choice. The other two options require manual intervention using InDesign's user interface.
|Required Metadata||Metadata is data about data. That is, if an e-book is considered to be data, then the information describing the e-book, like the title and creator, would be metadata.
Use this section to enter the required metadata elements that an EPUB file needs to be successfully validated.
|Identifier||Enter the identifier element(<dc:identifier>). The identifier contains an identifier, such as an ISBN or DOI, associated with the e-book. For more information about adding an identifier, see the Dublin Core Metadata Initiative.
If you leave this field empty, then InDesign automatically generates an identifier for you.
|Title||Enter the title element (<dc:title>). The title is the title for the e-book. For more information about adding a title, see the Dublin Core Metadata Initiative.
If you leave this field empty, then the title will be the Output name. For example, the title for hello-world.epub is hello-world.
|Creator||Enter the creator element(<dc:creator>). The creator is the name of the person or organisation who created the e-book. For more information about adding a creator, see the Dublin Core Metadata Initiative.
Including a creator element is a best practice for creating searchable e-books.
|Date||Enter the date element (<dc:date>). The date defines the publication date of the e-book. Use the DateTime format (YYYY, YYYY-MM, or YYYY-MM-DD) to enter the date. For example, you could enter 2020, 2020-08, or 2020-08-04.
For more information about adding a date, see the Dublin Core Metadata Initiative.
If you leave this field empty, then Typefi Server automatically generates <dc:date> to the current date and time.
