In the following documents, highlighted character strings cannot be set as a
keyword. The scanner may fail to correctly recognize the following kinds of
documents (characters) as text. However, by changing the color mode and/or
improving the image quality for scanning, such documents may be successfully
recognized.
Handwritten documents
Documents including smaller characters and scanned in low quality
Skewed documents
Documents including texts written in italic characters
Superscript/subscript letters and complex mathematical formulas
Characters are written against an unevenly-colored or patterned background
Example: Shaded characters
Documents containing a lot of characters to which effects are applied
Example: Characters to which effects such as Shadow and Outline are applied
The recognition time may be long for documents of complex layout as well as
documents including unreadable characters (due to print-through, smudges, or
skewed sheets) and containing text of uneven thickness or small black spots.
