4.8.6 Searchable PDF
When the file format is PDF, the scanned data can be converted to a searchable PDF.
The scanner may fail to correctly recognize the following kinds of documents
(characters) as text. However, by changing color mode and/or improving image
quality for scanning, such a document may be successfully recognized.
• Handwritten documents
• Documents including smaller characters and scanned in low quality
• Skewed documents
• Documents written in languages other than English
• Documents including texts written in italic characters
• Superscript/subscript letters and complex mathematical formulas
• Characters are written against an unevenly-colored or patterned background
• Characters to which effects (Shadow, Outline, and the like) are applied
• Shaded characters
• Documents of complex layout as well as documents including unreadable
characters due to print-through and smudges
(For such documents, the recognition time may be long)
Creating a searchable PDF will take some additional time.
