ADOBE ACROBAT 7.0 64 Section 11: Repairing reading order and basic tagging problems TouchUp Reading Order preferences The Preferences dialog box (Edit > Preferences) has a TouchUp category that lets you select how Acrobat Professional analyzes the content on a page in order to generate the reading order that Acrobat displays when you use the TouchUp Reading Order tool. English-language text, for example, typically follows a left-to-right, top-to-bottom order. The default setting is Left To Right, Top To Bottom. You can change this setting to accommodate certain types of documents or languages. The touchup workflow-an orderly approach to repairing reading order and tags The power of the TouchUp Reading Order tool is easy to manage if you approach the touchup process systematically. Start by opening the TouchUp Reading Order dialog box, selecting all the options to show content on a page, and opening the Order tab. Close the TouchUp Reading Order dialog box, and then go page by page through the document, looking at all the highlighted regions for each page. Get a quick feel for the overall reading order of the numbered regions. Note any reading order and accessibility problems, such as figures that have been inappropriately combined with text, tables that aren't marked as tables, and figures that are missing alternate text. You may also want to have the results of the most recent accessibility Full Check open to guide your inspection and repairs. Note: The task of repairing tables is discussed later in this section, so you may want to turn off Show Table Cells for now, to keep them from interfering with your basic repair work. Once you're ready to start repairs, follow these general steps: Step 1. Fix highlighted regions. Remove nonessential elements (for example, running heads, background graphics, and text-as-graphics) from the reading order. Repair improperly grouped text runs, such as captions that are separated from their figures and columns that are incorrectly combined. If the document is a form, make sure that each form field and its label are combined into their own highlighted region. Be aware that highlighted regions, because they are always rectangular, may not precisely cover the content that you want (as in text runs that are Lshaped, columns that have inset text blocks, or text that runs diagonally). Overlapping highlighted regions do not necessarily indicate a reading order problem. Step 2. Check the reading order of the remaining highlighted regions. Follow the sequence of numbering to verify that the content makes sense when you read the text in the order in which the regions are numbered. Use the Order tab to change the reading order as needed. Step 3. Add alternate text. Add alternate text to figures. If the document is a form, also add descriptive text to the form fields. Step 4. Fix basic table problems. Tasks here include tagging tables that are not identified as tables and tagging cells that have been improperly merged or split. Step 5. Test as you go. Use Reflow view to check the reading order of more complex pages. Repeat steps 1 through 4 until the content reads in the proper order. (Fixing some reading order problems may require that you rearrange elements in the tag tree by using the techniques in "Section 13: Fixing advanced accessibility problems" on page 92.) Step 6. Run an accessibility Full Check. Full Check can highlight figures and form fields that still lack alternate text, and it may uncover other accessibility problems that you can repair by using the techniques in "Section 12: Adding other accessibility features" on page 85. The rest of this section describes the four basic techniques that you need to know when you use the TouchUp Reading Order tool, and shows how to fix common problems that you may encounter in this phase of the Adobe PDF accessibility workflow.

Section 11: Repairing reading order and basic tagging problems
TouchUp Reading Order preferences
The Preferences dialog box (Edit > Preferences) has a TouchUp category that lets you select how Acrobat Professional
analyzes the content on a page in order to generate the reading order that Acrobat displays when you use the
TouchUp Reading Order tool. English-language text, for example, typically follows a left-to-right, top-to-bottom
order. The default setting is Left To Right, Top To Bottom. You can change this setting to accommodate certain types
of documents or languages.
The touchup workflow—an orderly approach to repairing reading order
and tags
The power of the TouchUp Reading Order tool is easy to manage if you approach the touchup process systematically.
Start by opening the TouchUp Reading Order dialog box, selecting all the options to show content on a page, and
opening the Order tab. Close the TouchUp Reading Order dialog box, and then go page by page through the
document, looking at all the highlighted regions for each page. Get a quick feel for the overall reading order of the
numbered regions. Note any reading order and accessibility problems, such as figures that have been inappropriately
combined with text, tables that aren’t marked as tables, and figures that are missing alternate text. You may also want
to have the results of the most recent accessibility Full Check open to guide your inspection and repairs.
Note:
The task of repairing tables is discussed later in this section, so you may want to turn off Show Table Cells for now,
to keep them from interfering with your basic repair work.
Once you’re ready to start repairs, follow these general steps:
Step 1. Fix highlighted regions.
Remove nonessential elements (for example, running heads, background graphics,
and text-as-graphics) from the reading order. Repair improperly grouped text runs, such as captions that are
separated from their figures and columns that are incorrectly combined. If the document is a form, make sure that
each form field and its label are combined into their own highlighted region. Be aware that highlighted regions,
because they are always rectangular, may not precisely cover the content that you want (as in text runs that are L-
shaped, columns that have inset text blocks, or text that runs diagonally). Overlapping highlighted regions do not
necessarily indicate a reading order problem.
Step 2. Check the reading order of the remaining highlighted regions.
Follow the sequence of numbering to
verify that the content makes sense when you read the text in the order in which the regions are numbered. Use the
Order tab to change the reading order as needed.
Step 3. Add alternate text.
Add alternate text to figures. If the document is a form, also add descriptive text to the
form fields.
Step 4. Fix basic table problems.
Tasks here include tagging tables that are not identified as tables and tagging cells
that have been improperly merged or split.
Step 5. Test as you go.
Use Reflow view to check the reading order of more complex pages. Repeat steps 1 through
4 until the content reads in the proper order. (Fixing some reading order problems may require that you rearrange
elements in the tag tree by using the techniques in “Section 13: Fixing advanced accessibility problems” on page 92.)
Step 6. Run an accessibility Full Check.
Full Check can highlight figures and form fields that still lack alternate text,
and it may uncover other accessibility problems that you can repair by using the techniques in “Section 12: Adding
other accessibility features” on page 85.
The rest of this section describes the four basic techniques that you need to know when you use the TouchUp Reading
Order tool, and shows how to fix common problems that you may encounter in this phase of the Adobe PDF acces-
sibility workflow.
