Logical Read Order
Documents are more accessible if they have been authored with a logical structure in mind. Use FrameMaker to define and create document structure, such as titles, chapters, headings, and multicolumn text, in order to make it easier for assistive technologies, such as screen readers to understand the logical reading order of the content without any ambiguity.
For example, if a tagged Adobe PDF document has been correctly authored using two columns to create a two-column format, the screen reader will read all the way down the first column and then proceed to the second column. On the other hand, if the writer used tabs to imitate the look of two-column text, the screen reader would not recognize the layout as two-column. Instead, it would simply read horizontally, going from the first line in the first column and then tabbing over to the first line in the second column.
The order in which you create frames in the original FrameMaker document is the order that is represented in the logical structure tree of your tagged Adobe PDF file. Therefore, if you move frames in the FrameMaker layout, the structure of your tagged Adobe PDF file will still show frames in the order created. To correct reading order problems, you can use tools in Adobe Acrobat Professional.
Note: Screen readers may not be able to correctly read multicolumn text if it is viewed in FrameMaker. If you want your FrameMaker documents to be read by screen readers using FrameMaker, use single-column formatting. Otherwise, save the document as tagged PDF.
