What characteristics will an Accessible

Checking for Document Accessibility
Creating an Accessible Document in:
Word
PowerPoint
Adobe Acrobat
Additional Resources
Alternative Textbooks
The text in the document can be selected by character or word.
The selectable text is accurate and matches what is visible in the document
The text in the document can be enlarged without compromising the quality of the text
Graphical information can be interpreted with a text description
Text in some documents is embedded in images
Text embedded in images cannot be read by TTS or reformatted
Most frequently in PDF’s or Publisher Provided PPT
Check by attempting to Highlight a single Character or Word
This issue usually happens in PDF documents
Save the file as Plain Text and compare
Activate Read Outloud in Adobe’s View menu and read Current Page
Fix by running Find OCR Suspects
Check by using the program to Zoom in to the image or enlarge it to 200% and 400%
If grainy and distorted:
rescan the image from which it came at a higher resolution
render a new graphic from the original document using a higher resolution
recreate the graphic using scalable vector graphics.
BAD SCAN AT 400X GOOD SCAN AT 400X
To Check for Alt Tags:
Hold your mouse over the graphic’
Right-click on the image and look under

4.
Right Click on the image.
Click on Size.
Select the Alt Tag tab.
Type a description of the graphic in the Alt
Tag edit field.
If using symbols like μ, 98.6°, or € please use the Unicode character, in the Symbol Finder, instead of an image
For Math Expressions please use Equasion
Editor or MathType to create the expression
Good because it is scalable and does not degrade when magnifying
No simple way to creat an Alt Tag.
If necessary type a description of the graphic before or after the WordArt
Important for Screen Reader navigation
Headings should be nested
Especially important if the document is very long or if it will be converted into a PDF.
Slide templates built into PPT use elements properly
Include Headings, bulleted lists, image placeholders
Style schemes can be applied that make the text eisier to read
Used for descriptions too long for Alt Tags
Describe WordArt or SmartArt
Adding info not included on the slide
Describe purpose of data presented

Office Button and Save As PDF
If scanning a document to creat a PDF use
