Overview

Desktop Version of CommonLook PDF Quick Start Guide:

This section of the Guide is specifically for users in the desktop plugin version of CommonLook PDF.  If you are using the Advanced editor, select this link to the CommonLook PDF Advanced Editor Quick Start Guide.

 To follow along, download the PDF document at the very bottom of this page. It is titled "Rock on DC Music Festival." 


Before We Begin:

This guide is designed to take the new CommonLook PDF user step by step through the process of remediating and validating the accompanying PDF document. Although the document is relatively simple, by taking the concepts and applying them to other documents, the intent is that you’re able to get a good start at remediating your own files.

A typical workflow for PDF remediation may include running OCR (Optical Character Recognition – for scanned documents), adding any interactive elements (links, forms, buttons, etc.), and then adding tags to the document before fixing it in CommonLook.  These steps aren’t needed in this sample document so we can move right into opening CommonLook and getting started.

The Quick Start steps below are specific to the accompanying "Rock on DC Music Festival" PDF.

Important Note:  To thoroughly explain all of the functionality in CommonLook would make this Quick Start Document unreasonably long.  The instructions below provide one way to fix the PDF.  Feel free to explore the software on your own or to inquire about formal training to receive more in-depth instruction. It's also worth noting that if any of the screenshots or images are appearing a bit small, you can select them to enlarge them.


Opening CommonLook (Desktop):

Please note: If you are unable to open CL PDF, if you get an error message about a "handling exception," or if Acrobat crashes, you likely have Protected Mode (in Acrobat) turned on.  Please refer to this article in our Knowledge Base about Opening CommonLook PDF and troubleshooting this issue. Some other common hiccups are described and managed in that article too.

  1. Open the PDF document in Adobe Acrobat (Standard, Professional, or DC).
  2. In the Acrobat toolbar, choose Plug-Ins, scroll to CommonLook, and select CommonLook PDF.

The Plug-ins menu in Adobe Acrobat expanded to show the option for CommonLook and CommonLook PDF.

Important note:  After opening CommonLook for the first time, follow these steps:

  1. Navigate to the Settings tab in the Ribbon,
  2. In the Business Group, select User Preferences,
  3. If not already done, check the box next to “Consider elements containing only empty spaces to be empty:”
  4. Choose “Ok.”

Screenshot highlighting the steps as described in the preceding list. Select Settings then User Preferences and then the checkbox to consider elements containing only spaces to be empty. The OK button is also highlighted.

Tip:  Also in the Business Group is a button to “Reset Panels Location.”  This button is very helpful to move panels back to their default location (including whether or not various panels are open and visible).  It might be worthwhile to get into the habit of opening CommonLook PDF and then immediately choosing this option.  This way, you’ll always know where the various panels are located in the user interface (at least until you get used to things and then decide to configure your panels differently, for example).

The CommonLook Workflow:

The recommended workflow when using CommonLook to remediate PDFs is to first navigate through the Tags making sure that the correct tags are being used for the content and that they’re in the correct reading order and then, second, to run a verification and see if there’s anything you missed.  This workflow, which we’ll follow in this Quick Start Guide, lends itself to a more accurate and efficient process as opposed to (what many people do when using Acrobat) running a full-check, fixing issues, running another check, fixing other issues, etc., until you get a “clean” report. For more info on the CommonLook Workflow, check out our Knowledge Base article titled, What is the recommended workflow when using CommonLook PDF?

Fixing the PDF

  1. Navigate to the Tags panel (on the left side of the screen – OR hold down the Control key and press Tab to open the Active Tools Window and then select Tags) and expand the Tags root by double-clicking it, clicking on the caret, or using the Right-arrow on your keyboard.
    The Tags root is highlighted in the Tags panel.

Fix the H1 (for the Title of the document)

  1. Select the first Paragraph tag in the Tags tree.  In the physical view, the first line of the title will be highlighted.  Tip:  Unless you really need to open tags it’s recommended that you don’t open them. In our teaching experiences, we find that the more open people’s tags are, the more confused they get. If you’re using the physical view for guidance on selecting tags, noticing what each tag contains, etc., then keep the tags themselves closed as much as possible. That said, screen reader users, when you select the first Paragraph tag, you’ll hear something along the lines of “P tag collapsed” – keep in mind that different screen readers may say slightly different things. Use the right arrow on your keyboard to open it and hear the tag’s contents.
    Screenshot showing the first Paragraph tag selected in the Tags tree and the text highlighted in the physical view.
  2.  Navigate to the second Paragraph tag in the Tags tree.  (Open it only if you need to!)  It contains the text of the second line of the title.  We need both lines of the title to be in one H1 (heading 1) tag.
    1. In the physical view, highlight (draw a box around) both lines of the title of the document.  When you do this it’ll select both text elements inside the Paragraph tags. OR navigate back up to the text inside the first P tag and then, with it selected, hold down the Control key and navigate down to the text element inside the second P tag.  While still holding the Control key press the Spacebar.  This’ll select both text elements inside both P tags.  (Important: If selecting the text inside the P tags from within the Tags tree, select the text in the first P tag first and then the text in the second P tag!)
      Screenshot showing the first two Paragraph tags selected in the Tags tree and both lines of the title highlighted in the physical view.
    2. Navigate to the Insert tag tab and use the button to put your selected text into an H1 (or use the keyboard shortcut Ctrl+1).
  3. The H1 that you just created will be open – perhaps even the text element will be open to the text run level.  Use the Right-arrow on the keyboard, or double-click, to close it.
  4. The H1 is nested inside one of the original P tags. We need to “push” the H1 out of the P tag.  To do that, right-click (or open the context menu) on the H1 and, in the context menu, navigate to, and choose, “Level up” (or use the keyboard shortcut Ctrl+P).
    Screenshot showing the new H1 tag nested in a Paragraph tag. The context menu is open and Level Up is highlighted.
  5. When you “Level up” your H1 it’ll get pushed out of the P tag and will become the first tag in the Tags tree.

Clean-up Empty Tags

Next, Clean up the empty P tag that was the second tag in the tree.  To do that:

  1. Right-click on the tag (open the context menu),
  2. Navigate to “Clean up,”
  3. Expand the sub-menu and navigate to “Skip empty cells.”  Or, use the keyboard shortcut Ctrl+E.
    The context menu is open on the empty P tag and Clean up and Skip empty cells are both highlighted.

Linearize an Improperly-Used Table:

Now that the Figure tag and the black lines have been artifacted, the next tag we encounter is a Table tag.  In this instance, a table was used in the authoring phase to format this section of the document but it’s not a data table and, therefore, it shouldn’t be tagged as a table.

  1. Select the Table tag in the Tags tree,
  2. Right-click on it (open the context menu),
  3. Navigate to Linearize Table,
  4. Choose Horizontally. The cells in the table are converted to one Figure tag containing the image and three P tags.
    The Table tag is selected and its context menu is open. Linearize Table and the option for Horizontally are highlighted.
  5. Verify the reading order for the Figure tag and the P tags by either clicking on them or using the down-arrow.

Alternative Text for Figure Tags that aren’t Decorative:

Because the Figure tag here contains an image that might be interpreted as “conveying information,” it needs to have Alternative text.

  1. Navigate to the Properties panel (using keyboard navigation, hold Control, press and release Tab, and then use the down-arrow to select Properties.  Then release the Control key.)
  2. Navigate to the Alt. text field,
  3. Type the Alt. text (in this example use something like “A band playing on the main stage at the music festival”),
  4. Press the Tab key.
    Screenshot showing the Figure tag selected, the image is highlighted, and Alternative text has been added in the Properties panel.

Verify Reading Order


After linearizing the Table and adding Alt Text to the Figure tag for the band playing on-stage, navigate through the new Paragraph tags, verifying the reading order.  They are likely in the correct order, but it's always a good idea to confirm that, especially after linearizing a table. 


Convert the P tag to the Proper Heading Tag


“Dates and Ticket Prices,” is incorrectly tagged as a Paragraph.

  1. With the P tag containing “Dates and Ticket Prices” selected, navigate to the Convert tag menu in the toolbar.
    Screenshot of the CommonLook toolbar with the Convert tag tab highlighted. 
  2. In the ribbon, choose the “H2” button to convert the Paragraph tag to an H2 (or use the keyboard shortcut Ctrl+Shift+2).
    Screenshot showing a P tag selected in the Tags tree and the convert to H2 button highlighted in the ribbon of the Convert tag tab.

Merging Tags

After the H2 for “Dates and Ticket Prices,” there are two sentences, each in their own Paragraph tag. One sentence is about when the music festival is and the other is about how much it costs (indicating that the actual prices are in the table below that sentence). Let’s combine the text in these two tags so that we only have one P tag. One way would be to select the text, put it all in a new P tag (like we did with the H1 at the beginning) and then “Level up” that new P tag so that it’s not nested inside one of the P tags that’s already there. However, there’s another (perhaps easier) technique.

  1. Select the first of the two P tags,
  2. Holding Shift (or Control), select the second P tag,
  3. Right-click (open the context menu) and choose “Merge tags” (or use the keyboard shortcut Ctr+M).
    Screenshot showing two Paragraph tags selected in the Tags tree, the context menu is open, and the option to Merge Tags is highlighted.You may notice that now you have one P tag with two text elements inside and you don’t have an empty P tag left behind. When merging tags, CommonLook will remove empty tags automatically. There’s also no need to “Level up!”

Tagging a Data Table

Next, there’s a data table in the physical view.

For a table to be tagged correctly, it needs to not only be “structurally sound” (a Table tag containing Table Rows (TR) which, in turn, contain Table Header (TH) and/or Table Data (TD) cells), but the header cells also need to be assigned the proper scope – column or row – so that the table information is correctly presented to individuals using assistive technology. To verify that the table has been built correctly, and that headers are tagged properly and assigned the correct scope, follow these steps:

  1. Right-click (open the context menu) on the Table Tag in the Tags tree,
  2. Choose (at the bottom of the context menu) “Show Table Editor” (you may need to scroll in the context menu).
    Screenshot showing the Table tag context menu open and the Show Table Editor option highlighted.
  3. Verify, in the Table Editor, that the layout matches the table in the physical view. (In this example, it does.  Concepts like fixing tables, including redrawing/ correcting complex data tables, and more, are covered in our in-depth training courses.)
  4. In the Table Editor, select the cell containing the text “Day” (the top left corner of the table),
  5. Hold down the Shift key and choose the cell for “Four-Pack.”  This selects the top row of cells.  (Alternately, with the “Day” cell selected, hold down the Shift key and use the Right-arrow to select the rest of the cells in the top row.)
  6. In the Table Editor, there are ten icons across the top. The fifth from the left is a button to change cells to TH (Table Header cells) and to assign the scope of column. Select this button. (Alternatively, with these cells selected in the Table Editor, use Ctrl+C.)
    Screenshot showing TD tags selected in the Tags tree and the button in the Table Editor to convert them to TH and assign the scope of Column is highlighted.
  7. In the Table Editor, choose the cell containing “Tuesday” and then hold down the Shift key and select the cell containing “3-Day Mega Pass” (again, multi-selecting these cells).  (Alternatively, after selecting “Tuesday,” hold down the Shift key and then use the Down-arrow on your keyboard to select the rest of the cells in that first column.)
  8. In the Table editor, the fourth button from the left is used to change cells to TH and assign them the scope of Row. Use this fourth button. (Alternatively, with these cells selected in the Table Editor, use Ctrl+R.)
    Screenshot showing TD tags selected in the Tags tree and the button in the Table Editor to convert them to TH and assign the scope of Row is highlighted.
  9. Close the Table editor by selecting the “x” in its top-right corner (not the “x” in the top right corner of the CommonLook window – that closes the software!). You can also close the Table Editor by selecting the Table tag in the Tags tree, opening its context menu, and “unchecking” the option “Show Table Editor.”
  10. As we worked in the Table Editor, various TR and TH/TD tags were opened in the Tags tree.  To close those tags, click the small arrow next to the Table tag in the Tags tree (or select the Table tag and use the Left-arrow key to close it).

Checking and merging more Tags


After the data table, the next tag in the Tags tree is an H2 tag that contains the text for the heading “Location.” This is the correct tag, as well as in the correct reading order, so it is accurate. The four Paragraphs immediately after the H2 each contain one line of the "Location" paragraph. These are unfortunately not connected under one Paragraph tag, so we must fix that. To fix this efficiently:

  1. Select the first of these P tags, which includes "On the Mall in..." and then, holding shift, select the fourth of these P tags, which includes "accessible." 
  2. With those four Paragraphs selected in that specific order, right-click on one of them in the Tags tree, or open the Context menu and select Merge Tags," or use Ctrl+M.
    Screenshot showing all four relevant Paragraphs selected and the Merge Tags command selected.
  3. Immediately after the newly merged Paragraph, we find another H2, which is tagged correctly. 

Generating a List Tag
The next four Paragraph tags are incorrect in that they should be tagged as a single List. List tags include very specific tag structures that include nested components within them. These nested components are List Items (LI), Labels (Lbl), and Body (LBody) tags. The structure is not hard to learn with practice, and the good news is that CommonLook PDF will create the List components automatically by following these steps:

  1. Highlight the list in the physical view of the document.  Make sure to select the bullets in the list as well as the text for the list items.  (Alternatively, select the text in the Tags tree.)
  2. Navigate to the far right side of the Insert tag tab to the “Generate tag from selection” group and choose the “List” button. (Keyboard shortcut: Ctrl+9) Screenshot of the ribbon on the Insert tag tab. The button the Generate a List from the Selection is highlighted.
  3. After tagging your List, move it in the Tags tree so that it’s a sibling to the H2 for “Participating Vendors.”  (You can do this with Cut and Paste, “Level up” and “Change tag order,” or by dragging it where you want it to go.)
  4. Clean up the empty tags that are left behind.  Note:  There may be tags left behind, after tagging the list, that contain the spaces after the bullets in the list.  Because those spaces aren’t important content, they don’t need to be tagged.  The “Clean up” function will automatically remove them, placing them in Artifact containers in the Untagged Content.
  5. Verify that the list was tagged correctly.  Open the list tag and find your four LI (List Item) tags.
  6. Screenshot of a List tag opened, showing the four List Item tags inside. The text for the list items is highlighted in the physical view.
  7. Open the List Item tags to reveal their nested (child) Lbl (Label) and LBody tags.  Selecting the Lbl tags will highlight the bullets in the physical view, selecting the LBody tags will highlight the text of the list items in the physical view.  OR, open the Lbl and LBody tags to verify their contents.
    Screenshot showing the first List Item tag opened in the Tags tree. It contains a Label and an LBody tag. The Label and LBody tag are selected and their contents are highlighted in the physical view.
  8. After you’ve verified that the list was tagged correctly, close the List tag so that the Tags tree is less confusing.
  9. After the List, in the Tags tree, there’s a Paragraph tag.  Selecting it highlights what should be the next paragraph to be read in the document.  This tag is correct and doesn’t need anything else done with it!

Correct Figure Issues

  1. In the set of three Figure tags near the bottom of the Tags tree, when you select the first one, you’ll notice that the logo on the right side of the page is highlighted (as opposed to the one on the left). Hold down the Control and Shift keys and then press the Down-arrow twice to reorder the Figure tags (that's the shortcut for "Change tag order").
    Screenshot showing the right-most Figure selceted with the Change Tag Order command highlighted.
  2. Next, select them in order, from top to bottom, to verify that the logos will be read from left to right as they appear on the page.  
    Note:  As addressed earlier in this guide, Figure tags like these, that contain actual “content,” require Alternative text.  However, we are going to skip that now and come back to it in the Verification phase – to learn another way to address Alt text for images.
  3. The last Paragraph in the Tags tree is tagged correctly, so, again, no further work is needed here, and you've reached the bottom of the document!

Adding the Document Tag

When you’ve finished checking and fixing the tags, navigate back up to the top of the Tags tree, right-click on the Tags root (open the context menu) and choose “Add Document tag.”  This wraps everything up in a Document tag and indicates that this is one full and complete document.

Screenshot showing the Tags root selected, its context menu open, and the option to Create Document tag is highlighted.

Congratulations – you’ve checked the tags and made some fixes!  It’s time to run a Verification and make sure we didn’t miss anything!


Verifying Document Compliance (and Fixing What You Missed)

After verifying (and fixing) the tags and the reading order, follow these steps to run a Validation:

  1. Navigate to the Standards panel (on the right side of the screen above the Properties panel).  (Remember the combination of Control, Tab, and then the Down-arrow in the Active Tools Window if needed.)
  2. Select “Standards” and then double-click or press the Right-arrow on your keyboard to open the menu.
  3. Similarly, navigate to and open the “Structural” and “Accessibility” menus.
  4. From the “Structural” menu, choose ISO 32000-1:2008.  (This is the standard on “how to make a PDF” and will test the structural integrity of the document.)
  5. Hold down the Control key and, in the Accessibility menu, choose WCAG 2.2 AA. (When holding the Control key either click on WCAG 2.2 or use the Down-arrow to navigate there and then select it by pressing the Spacebar.
    Note:  In this guide, we’ll validate against WCAG 2.2.  Choose an alternate standard if needed.
  6. Navigate to, and choose the “Full Validation” button.
    Screenshot of the Standards panel with the Structural and Accessibility menus open. ISO 32000-1:2008 and WCAG 2.1 are highlighted. The Full Validation button is also highlighted.
  7. Go to the Results panel when it opens, across the bottom of the middle panel.  (By keyboard, press and hold Control and then press the Tab key.  When the Active Tools Window opens, use the Down-arrow to navigate to Results.)  Note:  A lot of people get stressed when the Results panel opens because they think CommonLook is listing a whole lot of failures.  This is not the case.  CommonLook lists every checkpoint for the standards chosen and their status, whether it’s Passed, Failed, or requires manual verification, for example.  Don’t stress at this point!
  8. In the Results panel, navigate to the “Filter by:” drop-down menu and expand it.
  9. Uncheck the “All” checkbox.
  10. Check the boxes for Failed, User Verification, and Warning.  Now CommonLook is listing the issues, or the potential issues in the document.

Screenshot of the Results panel with the "Filter by" menu open and the checkboxes for Failed, User Verification, and Warning selected.

Fixing the Issues

Failures:

  1. Select the first Failure in the Results panel.  The second of the three logos, at the bottom of the page gets selected.  We’ll explore the issue and solution in the following steps:
    1. Right-click (open the context menu) on the error and choose “Fix.”  The Fix Wizard will open.
      Screenshot showing Step One in the Fix Wizard to correct the issue of a Figure tag not having Alternative text.In the Fix Wizard, along with a description of the failure, under “Fix Options,” there’s a drop-down menu with different ways to correct the problem.  Because this Figure tag needs to have Alternative text, we’ll use the first option shown – to “Provide Alt., Actual, or Expansion text.
    2. Choose “Next.”
    3. In Step 2, choose to “Provide Alt. text for the tag” and then “Next.”
      Step Two in the Fix Wizard for applying Alt text to Figures. The drop-down menu is open showing options to provide Alt, Actual, or Expansion text.
    4. Finally, in Step 3, enter the Alternative text needed for the image.  In this case, we’ll enter “Logo for Radio Station Q 99.4.”
      Screenshot showing the Alt text added in Step 3 of the Fix Wizard.
    5. Navigate to the “Finish” button and select it.
      Note:  The steps above have addressed the failures remaining in this document if you followed the remediation steps prior to the Verification section.  If you have other failures, use the Fix Wizard to address those issues as well.

Warnings:
There is one Warning result to address. You might need to scroll to the bottom of your results panel to find it.

  1. In the Results panel, select the Warning item. Open the context menu on the result and select "Edit Checkpoint Status." Check the "Description" field for more information and valuable context.
  2. It reads “Page 1 contains content but does not define header or footer pagination artifacts. Please confirm this is correct.”  In this document, there aren’t any headers at the top of the page and there aren’t any footers at the bottom so you can safely change the status to “Passed.”
    Screenshot showing the Status changed to Passed in the Status dialog box.

User Verifications:
After the Failures and Warnings have been fixed, there are a number of items that require User Verification.  Validating a document can’t be an entirely automated process because a machine can’t, for example, verify that the Alt. Text on an image is appropriate for that image.  We can automatically test whether or not Alt. text is present for the image, but verifying that something is truly correct sometimes requires human interaction.  Likewise, while a machine can check a document to see whether or not color has been used, it cannot test to see if color is the only way information is being conveyed.  This is why the “user verification” results are very important.  Follow the steps below to address the User Verification items.

  1. In the Results panel, select the first User Verification item.  It’ll highlight the first image in the document (the main stage at the music festival) and select the Figure tag in the Tags tree.
  2. Right-click on, or otherwise open the context menu, and choose “Edit Checkpoint Status.”
  3. Read the description – here it’s asking whether or not the Alt. text that was provided for the Figure is appropriate.
  4. Assuming that the Alt. text is appropriate (because we typed it in during the remediation phase), in the Status drop-down menu, choose Passed.  Optional: Enter a Comment in the “Comments” field. Your comments will appear in the Compliance Report that we’re going to generate later.
    Screenshot of the Status Dialog box with the Status set to Passed, the description of the checkpoint, and a comment in the Comments field.
  5. Choose Finish.
  6. Select the next three User Verification items. They are asking us to  verify are for the other images in the document. The first one is for the radio station Q 99.4, then the logo for the radio station A105.8, and the third is for the logo with the dog in it.  One of these we added using the Fix Wizard previously, and the others were added before you downloaded the original document, so in this case, you are simply verifying it's accuracy. All of these Alt Texts are correct, so you can select the results and change their status to Passed. To do so, select the first, hold down the Shift or Control key on your keyboard, and select the others. With all selected, open the context menu, select "Change Status to" and then choose "Passed" from the sub-menu.
    Screenshot showing both results selected, with Passed selected from the Change Status to menu.
  7. Next, verify that the Table Summary is appropriate for the Table. This was also added before you downloaded the original document, so you are simply verifying its accuracy. Change that item’s Status to "Passed” using the same "Change Status to" menu you used previously.
    Screenshot showing results selected, with Passed selected from the Change Status to menu.
  8. The next item is asking us to verify that color use, contrast, format, layout, etc., aren’t the only way that information is being conveyed.  Seeing as this isn’t an issue in this document, change the status to “Passed.”
  9. The next checkpoint is asking specifically about the contrast ratio between text and the background of the document.  It's asking us to make sure that there is enough contrast, visually, so that content is easily read.  Again, we can pass this item.
  10. The next four results are asking, for all four of the images in the document, whether or not they have a contrast ratio of at least 3:1 with their surrounding content.  They do, so we can select all of these (4) "Non-Text Contrast" items and pass them.
  11. Next, we’re asked whether or not the Title of the document is appropriate.  It is, so we can pass this item as well.
  12. Finally, verify that the language setting (in this case, English) is correct. This can be passed as well.

Congratulations!  At this point, all of the errors in the document have been corrected.

Reporting Compliance

Once you’ve finished fixing the document, including the items that come up in the Verification phase, you can generate a Compliance Report.  This report will show that the document has been tested against the standards that you chose and the issues have been addressed.  In addition, if you typed comments in the Status Dialog box, they’ll be in the report as well.

  1. Navigate to the “Filter by:” drop-down menu at the top of the Results panel and check the box next to “All.”
  2. Go to the “Report” button (next to the drop-down filter options) and select it to generate a report.
  3. In the “Save As” dialog that opens, choose the file name and location for your report.  By default, they’ll be the same as for the PDF itself.  Note:  The report is saved as an HTML file.
  4. Save.

The document is now remediated.


Save and Close.  At the very top left corner in CommonLook, there are two disc icons.  The second one is for “Save and Close.”  When you’re done remediating the document, choose this option (keyboard shortcut Alt+2).  This’ll compress the file back down (if it got a little bit “inflated” during remediation), save your work, and close both CommonLook and Acrobat.

Screenshot with the Save and Close icon highlighted.
