\uD83D\uDCD8 Instructions
Overview: When creating an accessible PDF, the easiest way to start is with an optimized source file. When you use the accessibility features in the software of origin, the PDF is mostly done. Only light touch-ups would have to be done for the tags and reading order. Follow these instructions before you send your document, spreadsheet, or presentation to Adobe Acrobat.
Section 1.1: What Elements should my Document, Spreadsheet or Presentation have for a Successful PDF?
Headings should be real headings (no big or bold text)
Go to the Home Tab.
Click a Heading Style in the Styles Group.
Lists should be real lists (not just items with an asterisk).
Click the Home Tab.
Click Paragraph Group and select a List Style.

Click the References Tab.
Click the Table of Contents button, then click the style of the table.

...
Tab key.
Click the Layout Tab.
Go to the Page Setup Section, and click Columns.
Tables should be real tables.
Go to the Insert Tab
Click the Table Button, and select the number of rows and columns needed. Do not use the Draw Table option.
Section 1.2: Semantic Headings
...
Have Semantic Headings (No big or bold text).
Start at Heading Level 1. (The biggest heading type).
Not skip levels. (Level 1 comes first, then 2, then 3).
Have a good outline of a documents hierarchy.
Be accurate.
Headings provide readers with an outline of a document. Users can jump from heading to heading between headings and can see what is going to be in the document without having to read it all. Headings are have six levels of tags. <H1> through <H6>. These tags are important because they establish part of the hierarchy. An <H1> tag should always be above the rest of the heading tags. An <H6> tag is always the lowest heading tag. Heading 1 level tags are always labeled with a name for a section or sometimes a title. The lower heading tags are for sections within a section. Hence the importance of the hierarchy.
...
Keep all text fonts readable (use fonts like Verdana and Times New Roman).
Line spacing should be at least 1.5 within paragraphs.
Paragraph spacing is at least 1.5 times larger than the line spacing.
Text is never fully justified.
Warning |
---|
Fully justified text causes unneeded spacing between words. |
...
Section 1.4: Alternative Text
...
Alt text provides a description of images, graphs and charts, and other non-text content. Screen readers by default, cannot read these objects to a reader. If a screen reader scanned an image, without an alt text, the image would be skipped over. Alt text gives the screen reader the ability to read a description of the object to the reader. This is especially helpful to users who are blind or have low vision.
Go to the Insert Tab, find the Illustrations Panel and select Pictures.
Insert your photo. Then, in less than 150 characters, explain what the photo is.
Section 1.5: Color Contrast
Open your document, spreadsheet, or presentation
When typing in text, you want to consider the color contrast between the text and the background. For small text, (under size 18), a good contrast ratio is 7:1 or higher. For bigger text, (over size 18) a good contrast ratio is 3:1 or higher. Black text on a white background or 21:1 is considered to be the most accessible contrast ratio.
To color your text, highlight your text and go to the Font Panel Section in the Home Tab.
Select the Font Color Tab and choose a color.
Section 1.6: Links
Links are correctly designated (this occurs automatically in MS Word. This occurs when you type a URL and hit Enter ; the or Space. The link becomes clickable and a blue color and underline appear).
An example of a non-designated link would be a non-clickable, black, plain-text URL.
You can create a URL that is not a link, but only if it is being used as an example.
Links need to be visible from the surrounding text.
MS Word default works well (color change plus underline).
Link text is meaningful and not vague or generic.
