Prepare layers before exporting a book to PDF
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.
1 If you don’t want certain layers to be merged, give them unique names in each book document.
Layer names are case-sensitive, so “Art” and “art” layers are not merged.
2 In the Book panel menu, select Merge Identically Named Layers On Export.
Note: When you export the book to PDF, make sure that Create Acrobat Layers is selected. To select this option, you must
use Acrobat 6 (PDF 1.5) or later compatibility.
Export a book to PDF
1 Do one of the following:
• 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.
2 Specify a name and location for the PDF file, and then click Save.
3 Either choose a preset from the Adobe PDF Preset menu, or select a category from the list on the left of the Export
Adobe PDF dialog box, and then customize the options.
4 Click Export (Windows) or Save (Mac OS).
Reducing the size of PDFs
For PDF files that are intended to be distributed for viewing purposes only, you may want to reduce the size of PDF
files when you export from InDesign. Here are some of the size reduction techniques you can use in the Export
Adobe PDF dialog box:
• Choose [Smallest File Size] from the Adobe PDF Preset menu.
• In the Compression area, downsample images to 72 pixels per inch, select automatic compression, and select either
low- or medium-image quality for color and grayscale images. When you work with photographic images, use
Automatic (JPEG 2000) compression; when you work with images that are mostly solid color, such as charts and
graphs, use ZIP compression.
• In the Output area, use the Ink Manager to convert spot colors to process colors.
To reduce the size of PDFs, simply open the PDF in Acrobat 8.0 or later, choose Document > Reduce File Size, and
then specify the compatibility level. For greater control, choose Advanced > PDF Optimizer.
