Understanding and optimizing Reflow
You can reflow a PDF document to read it on handheld devices, smaller displays, or standard
monitors at large magnifications, without having to scroll horizontally to read each line. The Reflow
command facilitates the reading of documents; reflowed documents can't be printed or saved.
When you reflow an Adobe PDF document, some content carries into the reflowed document and
some doesn't. In most cases, only readable text reflows into the reflowed document. Readable text
includes articles, paragraphs, tables, images, and formatted lists. Text that doesn't reflow includes
forms, comments, digital signature fields, and page artifacts, such as page numbers, headers, and
footers. Pages that contain both readable text and form or digital signature fields don't reflow. Vertical
text reflows horizontally.
As an author, you can optimize your PDF documents for reflow by tagging them. Tagging ensures
that text blocks reflow and that content follows the appropriate sequences, so readers can follow a
story that spans different pages and columns without other stories interrupting the flow. (See Tagging
Adobe PDF documents for accessibility.)
If the tagged PDF document doesn't reflow the way you want, the content order of the PDF file may
contain inconsistencies, or the tagging process itself may be the cause. If the problem is simply that
words don't hyphenate the way you expect them to, you can insert special characters. Otherwise, use
the Content tab to resolve reflow problems. (See Using the Content tab.)
