升级软件

Upgrade to the most recent version of Microsoft Word. 如果你有Word 2016或 later, you should have a "Check 可访问性" option under the "Review" tab. Use this 工具 to identify and correct common accessibility issues identified by MS Word. You'll still have a couple of things to check and possibly correct once you've saved your Word 文档 as a PDF but this can significantly reduce the amount of work you'll 一旦你到了那里就需要做的事. 

使用标题 正确

Use 文档 标题 for structure, not style. One of the most common accessibility mistakes is 对我们来说e Headings for style purposes (e.g. to make text look bigger and bolder or a particular color). 如果你愿意 your text to look a certain way, use the text formatting 工具s such as font size, 粗体、斜体等. 直接. Or you can create custom styles using the Styles pane. Just don't use Headings such as 标题1, 2, 3, etc. 为了美观.

Why You Shouldn't 使用标题 for Styling Purposes

Screen reader technology uses Headings to convey the structure and organization of 对其用户的文档. Headings, such as 标题1, 标题2, etc. 创建文档 structure in the same way that a table of contents is organized. 单词(以及 Google Docs) can auto-generate a table of contents for your 文档 based on its 标题. It will assume 标题1 blocks are like "chapters" and will nest Heading 2 blocks as sub-sections of any 标题1 preceding it (and so on for 标题3, etc.). The bottom line is that Headings need to be nested properly to be accessible.

正确嵌套标题

Think of Headings the Same Way You Think of an Outline:

• 标题1 is the first tier of bullets in an outline such as this.
  • 标题2 is like any second-level bullet. In an outline, you can't skip to a third-level bullet without a second-level before it. Likewise, you should never skip a heading level 在你们的文档中. Doing so will create an accessibility issue.
    • 标题3 can only exist after level 2 and so on.
  • 标题2: You can come back 从 level 3 to level 2…
  • 标题2: ...and have as many same-level 标题 next to each other as the content necessitates. Note that you could also return to a 标题1 从 a 标题3, just not the other way around, just like this outline.
• 回到 标题1 signifies a whole new "chapter" or section of your content. 

使用表格获取数据 Not 布局

Use tables for data only, not for layout. Another common mistake that makes accessibility a challenge in PDFs is when a table has been used to visually lay out content in a 特定的方式. Tables should only be used for their intended purpose – to display content within a grid of columns and rows identified by column headers. Every column must have a header labeling the content of that column.

Images Require Alternate Text

从Word保存为PDF

Note: If you jumped straight here but skipped the Microsoft Word提示 section above, please go back and review that section. Unless you have very few minor edits to an 现有的 508 -兼容的 PDF, you always want to start 从 scratch in a new Word 文档 and "Save as" PDF – you'll be thankful that you did. 

升级软件

Obtain, or upgrade to, the most recent version of Adobe 杂技演员 Pro. 内置的 accessibility checker and some of its automated tasks, which can aid you in making your PDF 508 compliant, have significantly improved in more recent versions and should save you considerable time and frustration compared with older versions.

Fixing Your PDF 可访问性 Issues

The number and difficulty level of issues you may encounter can vary greatly. 然而, if we're simply talking about text-only 文档s and you've followed all of the tips in this primer thus far, you're probably going to have minimal work to do. 本指南 will not attempt to address the numerous, and at times highly technical, fixes for 大多数PDF问题. Instead, we will cover a couple of common and simple quick fixes 对于一个典型的基本文档.

Adobe 杂技演员 Pro has extensive 文档ation covering each of the issues you may encounter and this information can be easily found by right-clicking on any issue and selecting "解释" 从 the context menu. This will open a new tab in a browser and should scroll to the specific issue in the 杂技演员 User Guide. 在…的时候 writing, that user guide can be found at http://helpx.adobe.com/acrobat/user-guide.html, and the relevant information is located in the section titled 可访问性, Tags, 和回流.

修复标题

Not only does the title tell your users what this 文档 is about but it also becomes the text for the link that a Google search finds. Often a converted Microsoft Word 文档 inserts the title with the .docx extension and whatever other random file-naming conventions we have come up with. So even if this one passes, it's a good idea to 进去把它清理干净.

To check and update your PDF title, open up the main application's File menu, and 选择属性. In the Properties dialog, the default view is Description, and right there at the top is the Title. Check that it reads just as a title should, removing any dates, file extensions, underscores, or any other unnecessary characters.

Tip: Even though you're posting this 文档 to your PCC web page, Google and other search engines will still find it outside of this context so it's good to include "PCC" or "PACCD" in the title somewhere, in addition to the title of your 文档. 

Once you've updated the Title (and optionally Author, Subject, and Keywords) click OK. Now go back to the 可访问性检查器 results and right-click the "Title - “失败”错误，然后选择修复. The check mark should turn green. 别忘了 save the PDF (Control+S on Windows, Command+S on Mac) so that fix gets saved if someone else checks your PDF for accessibility issues later. 

修复替代文本

If you didn't add alternate text via Microsoft Word 从 the tips in Part 1 of this primer, you'll still have an opportunity to do it here. 展开备用文本 category and right-click on the "Figures alternate text - Failed" issue. 选择修复 从 the context menu and you will be presented with a dialog that allows you to add alternate text for every figure (image) that is missing it. 只要加上简短的描述 text in the text box provided and then either advance to the next image using the arrow button or click "Save and Exit." If you used the Decorative Image checkbox during the previous step, you may have a new set of errors after exiting this dialog. We recommend always including alternate text for each issue to avoid this quirk. 再一次。 once you've corrected all issues here and you've got the green checkmark, save the PDF (Control+S on Windows, Command+S on Mac)
