Edit layer properties

You can combine the default state setting, the visibility setting, and the print setting to control when a layer is visible and when it prints. If a layer contains a watermark, for example, you may want the layer to not show on-screen but always to print and always to export to other applications. In this case you can set the default state to on, the initial visibility to never visible (the image doesn’t show on-screen), and the initial print and initial export states to always print and always export. The layer need not be listed in the Layers panel, since all the state changes are handled automatically.

Note: The settings in the Layer Properties dialog box take effect only if Allow Layer State To Be Set By User Information is selected in the Documents preferences. If it is not selected, Layer Properties dialog box settings, other than Layer Name and Default State, are ignored.
  1. Click the Layers button in the navigation pane.
  2. Select a layer, and choose Layer Properties from the Options menu.
  3. In the Layer Properties dialog box, edit the layer name or any of the following properties, and then click OK:
    Option


    Description
    Default State


    Defines the initial visibility state of the layer when a document is first opened or when the initial visibility is reset. The eye icons for layers are initially shown or hidden based on this value. For example, if this value is set to off, the eye icon for a layer is hidden when the document is first opened or when Reset To Initial Visibility is chosen from the Options menu.

    Intent


    Select View to allow the layer to be turned on or off, or select Reference to keep the layer on at all times and permit editing of the properties. When the Reference Intent option is selected, the layer appears in italics.

    Visibility


    Defines the on-screen visibility of the PDF layer. You can show a layer when the document is opened, you can hide a layer when the document is opened, or you can let the default state determine whether a layer is shown or hidden when the document is opened.

    Print


    Determines whether a layer will print.

    Export


    Determines whether the layer appears in the resulting document when the PDF file is exported to an application or file format that supports layers.

    Any additional properties that the creator of the layered PDF has associated with a specific layer are shown in the box at the bottom of the Layer Properties dialog box.

About PDF Layers

Acrobat 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.

You can rename and merge layers, change the properties of layers, and add actions to layers. You can also lock layers to prevent them from being hidden.

Acrobat does not allow you to author layers that change visibility according to the zoom level. However, you can highlight a portion of a layer that is especially important by creating a bookmark that magnifies or hides the layer using page actions. You can also add links that let users click a visible or invisible link to navigate to or zoom in on a layer.

To retain layers when you convert InDesign CS or later documents to PDF, make sure that Compatibility is set to Acrobat 6 (PDF 1.5) and that Create Acrobat Layers is selected in the Export PDF dialog box.

Edit document metadata

PDF documents created in Acrobat 5.0 or later contain document metadata in XML format. Metadata includes information about the document and its contents, such as the author’s name, keywords, and copyright information, that can be used by search utilities. The document metadata contains (but is not limited to) information that also appears in the Description tab of the Document Properties dialog box. Document metadata can be extended and modified using third-party products.

The Extensible Metadata Platform (XMP) provides Adobe applications with a common XML framework that standardizes the creation, processing, and interchange of document metadata across publishing workflows. You can save and import the document metadata XML source code in XMP format, making it easy to share metadata among different documents. You can also save document metadata to a Metadata template that you can reuse in Acrobat.

Create and view document properties

View document properties
When you view a PDF, you can get information about it, such as the title, the fonts used, and security settings. Some of this information is set by the person who created the document, and some is generated automatically.

You can change any information that can be set by the document creator, unless the file has been saved with security settings that prevent changes.

  1. Choose File > Properties.
  2. Click a tab in the Document Properties dialog box.
Create document properties
You can add custom document properties that store specific types of metadata, such as the version number or company name, in a PDF. Properties you create appear in the Document Properties dialog box. Properties you create must have unique names that do not appear on the other tabs in the Document Properties dialog box.
  1. Choose File > Properties, and then select Custom.
  2. To add a property, type the name and value, and then click Add.
  3. To change the properties, do any of the following, and then click OK:
    • To edit a property, select it, change the Value, and then click Change.

    • To delete a property, select it and click Delete.

    To change the name of a custom property, delete the property and create a new custom property with the name you want.
