Advanced Text Recognition Options
Next to the document language you can also configure Advanced Text Recognition Options in
Readiris. You can modify the document characteristics Font type and Character pitch, which play an
important role in the recognition process, favor recognition accuracy over speed or vice versa and
use User Lexicons to assist the recognition.
To access the Advanced Text Recognition Options, click Settings > Advanced Text Recognition
Options.
Font type
Readiris distinguishes between "regular" and dot matrix printed documents. Dot matrix symbols (of
the type 9 pin) are made up of isolated, separate dots.
Special segmentation and recognition techniques are required to recognize dot matrix documents
and need to be activated.
 The font type is set to Automatic by default.
That way, Readiris recognizes "25 pin" or "NLQ" (Near Letter Quality) dot matrix, or other
"normal" printing.
 To recognize only dot matrix printed documents, click Dot matrix.
Readiris will recognize so-called "draft" or "9 pin" dot matrix printed documents.
Character Pitch
The character pitch is the number of characters per inch in a typeface. The character pitch can either
be fixed, in which case all characters have the same width, or proportional, in which case the
characters have a different width.
 The character pitch is set to Automatic by default.
 Click Fixed if all characters of the typeface have the same width. This is often the case in old
typewriter documents.
 Click Proportional if the characters of the typeface have a different width. Virtually all fonts
in newspapers, magazines and books are proportional.
