About PDF layers
Reader supports viewing, navigating, and printing layered content in PDFs created from applications such as
InDesign, AutoCAD, and Visio.
You can control the display of layers using the default and initial state settings. For example, if your document
contains a copyright notice, you can easily hide the layer containing that notice whenever the document is displayed
on-screen while ensuring that the layer always prints.
Show or hide layers
Information can be stored on different layers of a PDF. The layers that appear in the PDF are based on the layers
created in the original application. You cannot create layers in Reader; however, you can examine layers and show or
hide the content associated with each layer using the Layers panel in the navigation pane. Items on locked layers
cannot be hidden.
Note: A Lock icon in the Layers panel indicates that a layer is for information only. The locked layer’s visibility cannot
be changed.
1 Choose View > Navigation Panels > Layers, and then do one of the following:
• To hide a layer, click the eye icon. To show a hidden layer, click the empty box. (A layer is visible when the eye icon
is present, and hidden when the eye icon is absent. This setting temporarily overrides the settings in the Layer
Properties dialog box.)
• To show or hide multiple layers, choose an option from the Options menu in the Layers panel.
2 From the Options menu in the Layers panel, choose one of the following:
List Layers For All Pages Shows every layer across every page of the document.
List Layers For Visible Pages Shows layers only on the currently visible pages.
Reset To Initial Visibility Resets layers to their default state.
