Color-managing documents for online viewing

Color management for online viewing is very different from color management for printed media. With printed media, you have far more control over the appearance of the final document. With online media, your document will appear on a wide range of possibly uncalibrated monitors and video display systems, significantly limiting your control over color consistency.

When you color-manage documents that will be viewed exclusively on the web, Adobe recommends that you use the sRGB color space. sRGB is the default working space for most Adobe color settings, but you can verify that sRGB is selected in the Color Settings dialog box (Photoshop, Illustrator, InDesign) or the Color Management preferences (Acrobat). With the working space set to sRGB, any RGB graphics you create will use sRGB as the color space.

When working with images that have an embedded color profile other than sRGB, you should convert the image’s colors to sRGB before you save the image for use on the web. If you want the application to automatically convert the colors to sRGB when you open the image, select Convert To Working Space as the RGB color management policy. (Make sure that your RGB working space is set to sRGB.) In Photoshop and InDesign, you can also manually convert the colors to sRGB using the Edit > Convert To Profile command.

Note: In InDesign, the Convert To Profile command only converts colors for native, not placed, objects in the document.

View or change profiles for imported bitmap images (InDesign)

InDesign allows you to view, override, or disable profiles for imported bitmap images. This may be necessary when you are importing an image containing no profile or an incorrectly embedded profile. For example, if the scanner manufacturer’s default profile was embedded but you have since generated a custom profile, you can assign the newer profile.

1. Do one of the following:

   • If the graphic is already in layout, select it and choose Object > Image Color Settings.

   • If you’re about to import the graphic, choose File > Place, select Show Import Options, select and open the file, and then select the Color tab.

2. For Profile, choose the source profile to apply to the graphic in your document. If a profile is currently embedded, the profile name appears at the top of the Profile menu.
3. (Optional) Choose a rendering intent, and then click OK. In most cases, it’s best to use the default rendering intent.

Note: You can also view or change profiles for objects in Acrobat.

Preparing imported graphics for color management (Illustrator, InDesign, Photoshop)

Use the following general guidelines to prepare graphics for being color-managed in Adobe applications:

• Embed an ICC-compliant profile when you save the file. The file formats that support embedded profiles are JPEG, PDF, PSD (Photoshop), AI (Illustrator), INDD (InDesign), and TIFF.

• If you plan to reuse a color graphic for multiple final output devices or media, such as for print, video, and the web, prepare the graphic using RGB or Lab colors whenever possible. If you must save in a color model other than RGB or Lab, keep a copy of the original graphic. RGB and Lab color models represent larger color gamuts than most output devices can reproduce, retaining as much color information as possible before being translated to a smaller output color gamut.

Using a safe CMYK workflow

A safe CMYK workflow ensures that CMYK color numbers are preserved all the way to the final output device, as opposed to being converted by your color management system. This workflow is beneficial if you want to incrementally adopt color management practices. For example, you can use CMYK profiles to soft-proof and hard-proof documents without the possibility of unintended color conversions occurring during final output.

Illustrator and InDesign support a safe CMYK workflow by default. As a result, when you open or import a CMYK image with an embedded profile, the application ignores the profile and preserves the raw color numbers. If you want your application to adjust color numbers based on an embedded profile, change the CMYK color policy to Preserve Embedded Profiles in the Color Settings dialog box. You can easily restore the safe CMYK workflow by changing the CMYK color policy back to Preserve Numbers (Ignore Linked Profiles).

You can override safe CMYK settings when you print a document or save it to PDF. However, doing so may cause colors to be reseparated. For example, pure CMYK black objects may be reseparated as rich black. For more information on color management options for printing and saving PDFs, search in Help.

Color-managing imported images (Illustrator, InDesign)

How imported images are integrated into a document’s color space depends on whether or not the image has an embedded profile:

• When you import an image that contains no profile, the Adobe application uses the current document profile to define the colors in the image.

• When you import an image that contains an embedded profile, color policies in the Color Settings dialog box determine how the Adobe application handles the profile.

Managing process and spot colors

When color management is on, any color you apply or create within a color-managed Adobe application automatically uses a color profile that corresponds to the document. If you switch color modes, the color management system uses the appropriate profiles to translate the color to the new color model you choose.

Keep in mind the following guidelines for working with process and spot colors:

• Choose a CMYK working space that matches your CMYK output conditions to ensure that you can accurately define and view process colors.

• Select colors from a color library. Adobe applications come with several standard color libraries, which you can load using the Swatches palette menu.

• (Acrobat, Illustrator, and InDesign) Turn on Overprint Preview to get an accurate and consistent preview of spot colors.

• (Acrobat, Illustrator, and InDesign) Use Lab values (the default) to display predefined spot colors (such as colors from the TOYO, PANTONE, DIC, and HKS libraries) and convert these colors to process colors. Using Lab values provides the greatest accuracy and guarantees the consistent display of colors across Creative Suite applications. If you want the display and output of these colors to match earlier versions of Illustrator or InDesign, use CMYK equivalent values instead. For instructions on switching between Lab values and CMYK values for spot colors, search Illustrator or InDesign Help.

Note: Color-managing spot colors provides a close approximation of a spot color on your proofing device and monitor. However, it is difficult to exactly reproduce a spot color on a monitor or proofing device because many spot color inks exist outside the gamuts of many of those devices.

Change the appearance of CMYK black (Illustrator, InDesign)

Pure CMYK black (K=100) appears jet black (or rich black) when viewed on-screen, printed to a non-PostScript desktop printer, or exported to an RGB file format. If you prefer to see the difference between pure black and rich black as it will appear when printed on a commercial press, you can change the Appearance Of Black preferences. These preferences do not change the color values in a document.

1. Choose Edit > Preferences > Appearance Of Black (Windows) or application name > Preferences > Appearance Of Black (Mac OS).
2. Choose an option for On Screen:

   Option	Description
   Display All Blacks Accurately	Displays pure CMYK black as dark gray. This setting allows you to see the difference between pure black and rich black.
   Display All Blacks As Rich Black	Displays pure CMYK black as jet black (RGB=000). This setting makes pure black and rich black appear the same on-screen.

3. Choose an option for Printing/Exporting:

   Option	Description
   Output All Blacks Accurately	When printing to a non-PostScript desktop printer or exporting to an RGB file format, outputs pure CMYK black as using the color numbers in the document. This setting allows you to see the difference between pure black and rich black.
   Output All Blacks As Rich Black	When printing to a non-PostScript desktop printer or exporting to an RGB file format, outputs pure CMYK black as jet black (RGB=000). This setting makes pure black and rich black appear the same.

Set up color management

1. Do one of the following:
   • (Illustrator, InDesign, Photoshop) Choose Edit > Color Settings.
   • (Acrobat) Select the Color Management panel of the Preferences dialog box.
   
   
2. Select a color setting from the Settings menu, and click OK.

   The setting you select determines which color working spaces are used by the application, what happens when you open and import files with embedded profiles, and how the color management system converts colors. To view a description of a setting, select the setting and then position the pointer over the setting name. The description appears at the bottom of the dialog box.

   Note: Acrobat color settings are a subset of those used in InDesign, Illustrator, and Photoshop.

   In certain situations, such as if your service provider supplies you with a custom output profile, you may need to customize specific options in the Color Settings dialog box. However, customizing is recommended for advanced users only.

   Note: If you work with more than one Adobe application, it is highly recommended that you synchronize your color settings across applications.

Source: Adobe

Synchronize color settings across Adobe applications

If you use Adobe Creative Suite, you can use Adobe Bridge to automatically synchronize color settings across applications. This synchronization ensures that colors look the same in all color-managed Adobe applications.

If color settings are not synchronized, a warning message appears at the top of the Color Settings dialog box in each application. Adobe recommends that you synchronize color settings before you work with new or existing documents.

1. Open Bridge.

   To open Bridge from Creative Suite, choose File > Browse from an application. To open Bridge directly, either choose Adobe Bridge from the Start menu (Windows) or double-click the Adobe Bridge icon (Mac OS).

2. Choose Edit > Creative Suite Color Settings.
3. Select a color setting from the list, and click Apply.

   If none of the default settings meet your requirements, select Show Expanded List Of Color Setting Files to view additional settings. To install a custom settings file, such as a file you received from a print service provider, click Show Saved Color Settings Files.

How to create a Digital Signature in 9.0 Pro

Basic steps for producing consistent color

Consult with your production partners (if you have any) to ensure that all aspects of your color management workflow integrate seamlessly with theirs.

Discuss how the color workflow will be integrated with your workgroups and service providers, how software and hardware will be configured for integration into the color management system, and at what level color management will be implemented.

Calibrate and profile your monitor.
A monitor profile is the first profile you should create. Seeing accurate color is essential if you are making creative decisions involving the color you specify in your document.

Add color profiles to your system for any input and output devices you plan to use, such as scanners and printers.

The color management system uses profiles to know how a device produces color and what the actual colors in a document are. Device profiles are often installed when a device is added to your system. You can also use third-party software and hardware to create more accurate profiles for specific devices and conditions. If your document will be commercially printed, contact your service provider to determine the profile for the printing device or press condition.


Set up color management in Adobe applications.
The default color settings are sufficient for most users. However, you can change the color settings by doing one of the following:

• If you use multiple Adobe applications, use Bridge to choose a standard color management configuration and synchronize color settings across applications before working with documents.
• If you use only one Adobe application, or if you want to customize advanced color management options, you can change color settings for a specific application.

After you create a document, you can use a soft proof to preview how colors will look when printed or viewed on a specific device.

Note: A soft proof alone doesn’t let you preview how overprinting will look when printed on an offset press. If you work with documents that contain overprinting, turn on Overprint Preview to accurately preview overprints in a soft proof.
Use color management when printing and saving files.

Keeping the appearance of colors consistent across all of the devices in your workflow is the goal of color management. Leave color management options enabled when printing documents, saving files, and preparing files for online viewing.

About color management in Adobe applications

Adobe color management helps you maintain the appearance of colors as you bring images in from external sources, edit documents and transfer them between Adobe applications, and output your finished compositions. This system is based on conventions developed by the International Color Consortium, a group responsible for standardizing profile formats and procedures so that consistent and accurate color can be achieved throughout a workflow.

By default, color management is turned on in color-managed Adobe applications. If you purchased the Adobe Creative Suite, color settings are synchronized across applications to provide consistent display for RGB and CMYK colors. This means that colors look the same no matter which application you view them in.

Color settings for Adobe Creative Suite are synchronized in a central location through Adobe Bridge

If you decide to change the default settings, easy-to-use presets let you configure Adobe color management to match common output conditions. You can also customize color settings to meet the demands of your particular color workflow.

Keep in mind that the kinds of images you work with and your output requirements influence how you use color management. For example, there are different color-consistency issues for an RGB photo printing workflow, a CMYK commercial printing workflow, a mixed RGB/CMYK digital printing workflow, and an internet publishing workflow.

Creating a viewing environment for color management

Your work environment influences how you see color on your monitor and on printed output. For best results, control the colors and light in your work environment by doing the following:

• View your documents in an environment that provides a consistent light level and color temperature. For example, the color characteristics of sunlight change throughout the day and alter the way colors appear on your screen, so keep shades closed or work in a windowless room. To eliminate the blue-green cast from fluorescent lighting, you can install D50 (5000° Kelvin) lighting. You can also view printed documents using a D50 lightbox.

• View your document in a room with neutral-colored walls and ceiling. A room’s color can affect the perception of both monitor color and printed color. The best color for a viewing room is neutral gray. Also, the color of your clothing reflecting off the glass of your monitor may affect the appearance of colors on-screen.

• Remove colorful background patterns on your monitor desktop. Busy or bright patterns surrounding a document interfere with accurate color perception. Set your desktop to display neutral grays only.

• View document proofs in the real-world conditions under which your audience will see the final piece. For example, you might want to see how a housewares catalog looks under the incandescent light bulbs used in homes, or view an office furniture catalog under the fluorescent lighting used in offices. However, always make final color judgements under the lighting conditions specified by the legal requirements for contract proofs in your country.

Do you need color management?

Without a color management system, your color specifications are device-dependent. You might not need color management if your production process is tightly controlled for one medium only. For example, you or your print service provider can tailor CMYK images and specify color values for a known, specific set of printing conditions.

The value of color management increases when you have more variables in your production process. Color management is recommended if you anticipate reusing color graphics for print and online media, using various kinds of devices within a single medium (such as different printing presses), or if you manage multiple workstations.

You will benefit from a color management system if you need to accomplish any of the following:

• Get predictable and consistent color output on multiple output devices including color separations, your desktop printer, and your monitor. Color management is especially useful for adjusting color for devices with a relatively limited gamut, such as a four-color process printing press.

• Accurately soft-proof (preview) a color document on your monitor by making it simulate a specific output device. (Soft-proofing is subject to the limitations of monitor display, and other factors such as room lighting conditions.)

• Accurately evaluate and consistently incorporate color graphics from many different sources if they also use color management, and even in some cases if they don’t.

• Send color documents to different output devices and media without having to manually adjust colors in documents or original graphics. This is valuable when creating images that will eventually be used both in print and online.

• Print color correctly to an unknown color output device; for example, you could store a document online for consistently reproducible on-demand color printing anywhere in the world.

What is a color management system?

Color-matching problems result from various devices and software using different color spaces. One solution is to have a system that interprets and translates color accurately between devices. A color management system (CMS) compares the color space in which a color was created to the color space in which the same color will be output, and makes the necessary adjustments to represent the color as consistently as possible among different devices.

A color management system translates colors with the help of color profiles. A profile is a mathematical description of a device’s color space. For example, a scanner profile tells a color management system how your scanner “sees” colors. Adobe color management uses ICC profiles, a format defined by the International Color Consortium (ICC) as a cross-platform standard.

Because no single color-translation method is ideal for all types of graphics, a color management system provides a choice of rendering intents, or translation methods, so that you can apply a method appropriate to a particular graphics element. For example, a color translation method that preserves correct relationships among colors in a wildlife photograph may alter the colors in a logo containing flat tints of color.

Note: Don’t confuse color management with color correction. A color management system won’t correct an image that was saved with tonal or color balance problems. It provides an environment where you can evaluate images reliably in the context of your final output.

Movies and sounds (Part 4)

Add movies or sounds to PDFs

You can add movies and sounds to PDFs in Windows if the media is playable in Windows Media Player, Flash Player, RealPlayer, or QuickTime. In Mac OS, you can add QuickTime compatible movies and sounds to PDFs.

Before you add a movie or sound clip to a PDF, you must decide if your clip will be compatible—that is, playable—in Acrobat 6 and later, or in earlier versions as well. If you choose the Acrobat 6 Compatible Media option, you have many more choices, such as the option to embed the movie and add multiple renditions. However, users with earlier versions of Acrobat will have to download Adobe Reader to play your clip.

You can provide different renditions of the movie that play if the users’ settings vary. For example, you may want to include a low-resolution rendition for users with slow Internet connections.

Note: If an alert message tells you that no media handler is available, you must install the appropriate player before you can add clips to the PDF. For example, you must install QuickTime if you want to embed an MOV file in a PDF.

Multimedia Trust preferences

In the Multimedia Trust preferences, you can specify whether to play embedded multimedia files in trusted or nontrusted PDF documents. A trusted document is a document that you approved or that was produced by an author you approved. By setting your permissions to play multimedia only in trusted documents, you can prevent programs, macros, and viruses from playing on, and potentially damaging, your computer.

The list of trusted documents and authors is stored internally and can’t be viewed. If you add a certified document to the list, both the document and the author’s certificate are added to the list of trusted documents. All documents that are certified by this author are trusted. (Trusted documents also include PDFs that were created by authors in your list of trusted identities.)

To access these preferences, choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and then select Multimedia Trust from the left side of the dialog box.

Display Permissions For

Choose whether you want to display security permissions for trusted documents or other (nontrusted) documents.

Movies and sounds (Part 1)

Play Movies and Sounds

PDFs can include many types of movie and sound files, including (but not limited to) Flash, QuickTime, MP3, MPEG, and Windows Media files. These files may be accessed on a page or within a link, bookmark, form field, or page action. Each movie and sound file includes a play area from which the media can be activated. The play area typically appears on the PDF page as an image or a rectangle, but can also be invisible.

Note: You must have the necessary hardware and software installed to play the media files.

To help protect your computer from viruses, Acrobat solicits your approval before playing multimedia files from unverified sources. You can change this default behavior in the Multimedia Trust preferences.

Using the Hand tool or the Select tool, click the play area of the movie or sound file. When the pointer is positioned over the play area, it changes to the play mode icon.

About batch sequences

When you apply one or more routine sets of commands to your files, you can save time and keystrokes by using an automated batch sequence—a defined series of commands with specific settings and in a specific order that you apply in a single step. You can apply a sequence to a single document, to several documents, or to an entire collection of documents.

You can use the batch sequences provided or define your own. Batch sequences that you define appear (in alphabetical order) in the list of predefined sequences so that you can reuse them in later work sessions.

Developers can further enhance batch processing and other robust capabilities in Acrobat by using the Acrobat Software Developers Kit (SDK) to create scripts and plug-ins for their particular needs. For more information, visit the Adobe Solutions Network (ASN) (English only).

Editing layered content

You can select or copy content in a layered PDF document using the Select tool or the Snapshot tool. You can edit content using a touch-up tool. These tools recognize and select any content that is visible, regardless of whether the content is on a selected layer.

If the content that you edit or delete is associated with one layer, the content of the layer reflects the change. If the content that you edit or delete is associated with more than one layer, the content in all the layers reflects the change. For example, if you want to change a title and byline that appear on the same line on the first page of a document, and the title and byline are on two different visible layers, editing the content on one layer changes the content on both layers.

You can add content, such as review comments, stamps, or form fields, to layered documents just as you would to any other PDF document. However, the content is not added to a specific layer, even if that layer is selected when the content is added. Rather, the content is added to the entire document.

You can use the Create PDF From Multiple Files command to combine Adobe PDF documents that contain layers. The layers for each document are grouped under a separate heading in the Layers panel of the navigation pane. You expand and collapse the group by clicking the icon in the title bar for the group.

How To Split and Merge

Merge or flatten layers

Merged layers acquire the properties of the layer into which they are merged (the target layer). Flattening PDF layers hides any content that is not visible when the flattening operation is executed and consolidates all layers.

Important: You cannot undo either a merging or a flattening operation.

Merge layers

1. Click the Layers button, and select Merge Layers from the Options menu.
2. In the left pane (Layers To Be Merged), select one or more layers to be merged. Ctrl/Command-click to select multiple layers, and click Add. Click Add All to merge all layers.
3. To remove a layer from the center panel, select the layer or layers. Ctrl/Command-click to select multiple layers. When your selection is complete, click Remove.
4. In the right pane (Layer To Be Merged Into), select the layer into which to merge the selected layers, and click OK.

Flatten layers

Click the Layers button, and select Flatten Layers from the Options menu.

You can add links and destinations to layers, allowing you to change the view of a document when the user clicks a bookmark or link.

Note: In general, changes to layer visibility made using the eye icon in the Layers panel are not recorded in the Navigation toolbar.

Associate layer visibility with bookmarks

1. Set the required layer properties, visibility, and magnification level for the target PDF layer in the document pane.
2. Click the Bookmarks button, and choose New Bookmark from the Options menu.
3. Select the new bookmark, and choose Properties from the Options menu.
4. In the Bookmark Properties dialog box, click the Actions tab.
5. For Select Action, choose Set Layer Visibility, click Add, and then click OK.
6. Select the bookmark label in the Bookmarks panel, and name the bookmark.

Associate layer visibility with a link destination

1. Set the required layer properties for the destination in the document pane.
2. Choose View > Navigation Panels > Destinations.

   The Destination panel appears in a floating panel. You can add it to the other panels by dragging it to the navigation pane. If the panel is collapsed, click the Destinations button to expand it.

3. Click the Create New Destination button or select New Destination from the Options menu, and name the destination.
4. Select the Link tool , and drag in the document pane to create a link. (Because content is added to all layers, it doesn’t matter that you are apparently creating the link on the target layer. The link works from any layer.)
5. In the Create Link dialog box, select Custom Link and click Next.
6. Click the Appearance tab in the Link Properties dialog box, and set the appearance of the link.
7. Click the Actions tab in the Link Properties dialog box, choose Set Layer Visibility, and click Add.
8. Close the dialog boxes.
   
   You can test the link by changing the layer settings, selecting the Hand tool, and clicking the link.

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.

Add page transitions

You can create an interesting effect that occurs each time a page advances by using page transitions.

You can also set page transitions for a group of documents using the Batch Processing command.

1. Do one of the following:

   • Choose Advanced > Document Processing > Page Transitions.

   • In the Pages panel, select the page thumbnails you want to apply transitions to, and choose Page Transitions from the Options menu.

2. In the Set Transitions dialog box, choose a transition effect from the Transition menu. These transition effects are the same as those set in the Full Screen preferences.
3. Choose the direction in which the transition effect occurs. Available options depend on the transition.
4. Choose the speed of the transition effect.
5. Select Auto Flip, and enter the number of seconds between automatic page turning. If you do not select this option, the user turns pages using keyboard commands or the mouse.
6. Select the Page Range you want to apply transitions to.
   Note: If users select Ignore All Transitions in the Full Screen preferences, they do not see the page transitions.

Defining initial view as Full Screen mode for Presentation

Full Screen mode is a property you can set for PDFs used for presentations. In Full Screen mode, PDF pages fill the entire screen, and the Acrobat menu bar, toolbar, and window controls are hidden. You can also set other opening views, so that your documents or collections of documents open to a consistent view. In either case, you can add page transitions to enhance the visual effect as the viewer pages through the document.

To control how you navigate a PDF (for example, advancing pages automatically), use the options in the Full Screen preferences. These preferences are specific to a system—not a PDF document—and affect all PDFs that you open on that system. Therefore, if you set up your presentation on a system you control, you can control these preferences. To set the Full Screen preferences, choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS) and select Full Screen on the left.

Start an image editor using the TouchUp Object tool

By default, the TouchUp Object tool starts Adobe Photoshop (if installed) to edit images and objects. To use a different editing application, specify the application in the TouchUp preferences. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and select TouchUp on the left side of the Preferences dialog box. Click Image Editor (for bitmap images) or Page/Object Editor, (for vector images) and select the application on your hard drive.

1. Using the TouchUp Object tool, select the image or object or Shift-click to select multiple images or objects. If you change the object selection, the editing session terminates.
   To edit all the images and objects on the page, right-click/Control-click the page, and choose Edit Page.
2. Right-click/Control-click the selection, and choose Edit Image or Edit Object. (The available command depends on what is selected.)
   Note: If the image can’t open in Adobe Photoshop, verify that Photoshop is configured correctly. If a message asks whether to convert to ICC profiles, choose Don’t Convert. If the image window displays a checkerboard pattern when it opens, the image data could not be read.
3. Make the desired changes in the external editing application.
4. If you are working in Photoshop, flatten the image.

   If you change the dimensions of the image in Photoshop, the image may not align correctly in the PDF. Also, transparency information is preserved only for masks that are specified as index values in an indexed color space. Image masks are not supported. If you change image modes while editing the image, you may lose valuable information that can be applied only in the original mode.

5. In the editing application, choose File > Save. The object is automatically updated and displayed in the PDF when you bring Acrobat to the foreground.
   
   Important: For Photoshop, if the image is in a format supported by Photoshop 6.0 or later, your edited image is saved back into the PDF. However, if the image is in an unsupported format, Photoshop handles the image as a generic PDF image, and the edited image is saved to disk instead of back into the PDF.

Edit an object using the TouchUp Object tool

1. Choose Tools > Advanced Editing > TouchUp Object tool.
2. Select the object, right-click/Control-click the selection, and choose one of the following:

   Option	Description
   Place Image	Embeds an image file in the PDF.
   Set Clip	Sets a clipping region for the object, if one exists.
   Delete Clip	Delete Clip deletes objects that are clipping the selected object. For example, if you scale text and the resulting characters are clipped, selecting this option shows you the complete characters. This option appears only if you chose Set Clip.
   Flip Horizontal, Flip Vertical	Flip Horizontal flips the image horizontally, on the vertical axis. Flipping text blocks horizontally creates a mirror effect. Flip Vertical flips the image vertically, on the horizontal axis.
   Create Artifact	Removes the object from the reading order so it isn’t read by a screen reader or the Read Out Loud command.
   Edit Image, Edit Object	Starts the image editor or object editor you specify in the TouchUp preferences. Edit Image is available when a vector image is selected; Edit Object is available when a bitmap image is selected. Selecting these options removes tags from the PDF which may change how the PDF reflows and affect accessibility. For example, changing the location of an object affects the order in which that object (or its alternate text) is read by a screen reader.
   Rotate Clockwise, Rotate Counterclockwise, Rotate Selection	Rotate Clockwise and Rotate Counterclockwise rotate the selected object ninety degrees in the indicated direction. Rotate Selection lets you rotate the selection incrementally by dragging a selection handle in the direction you choose. You must click inside the selection to exit the rotate mode.
   TouchUp Properties	Lets you edit properties for the content, tag, and text, such as adding alternate text to an image to make it accessible.

Clip an object

1. Select the TouchUp Object tool .
2. Right-click/Control-click the object, and choose Set Clip. When you hold the pointer over the selection, the clipping icon appears.
3. Drag a selection handle in the direction you want until the clip rectangle displays the results you want.
4. Click inside the selection to exit the clipping mode.

Select an object

1. Select one or more objects:

   • Click the object with the TouchUp Object tool (Tools > Advanced Editing).

   • Click the object with the Select Object tool, or with the tool you used to create the object.

   • Right-click/Control-click the object and choose Select All from the context menu. If the Select Object tool is active and the document uses single page layout, all objects on the current page are selected. If the document is in any other page layout, all objects in the document are selected. If a tool on the Advanced Editing toolbar is active, all objects of that type in the document are selected.

   • Drag to create a rectangle around the desired objects. If the Select Object tool is active, all objects within the rectangle are selected. If an Advanced Editing tool is active, press Ctrl as you drag; all objects of the tool type within the rectangle are selected.

2. (Optional) Add one or more objects to the current selection:

   • Ctrl/Option-click an object.

   • Shift-click to add a range of objects. (The Select Object tool includes all objects when you Shift-click.) Using Shift selects all items that lie within the rectangular bounding box formed by all items in the selection (including the item that was just added).

Move or edit an object

A selected object usually shows a bounding box. Selection handles appear when the pointer is over the object. When the pointer is over a locked object, no selection handles appear. When you select multiple objects, the last object you select becomes the anchor and appears red; the others appear blue. The anchor object remains stationary during alignment operations.

To make another object in the selection the anchor object, Ctrl/Option-click the new target object twice, once to remove the object from the selection, and once to add it back to the selection. As the last object added to the selection, it becomes the anchor object.

When objects of the same type are selected and the selection covers multiple pages, you can change the appearance of the objects but not move them.

When you edit a text box, the entire text box is selected; however, the TouchUp Object tool cannot select individual characters that are part of larger text blocks. You must use the TouchUp Text tool to edit individual characters and words.

Use the Select Object tool to select and move objects such as form fields and links.

Use the TouchUp Object tool to select and move placed images, text blocks, and embedded objects.
