An example of typewritten text. All letters are of equal width (compare,
for example, "w" and "t"). For texts of this type, select Typewriter.
An example of a text produced by a fax machine. As you can see from
the example, the letters are not clear in some places, in addition to
noise and distortion. For texts of this type, select Fax.
Tip: After recognizing typewritten texts or faxes, be sure to select Auto before processing regular
printed documents.
Print quality
Poor–quality documents with "noise" (i.e. random black dots or speckles), blurred and uneven
letters, or skewed lines and shifted table borders may require specific scanning settings.
Fax
Newspaper
Poor–quality documents are best scanned in grayscale. When scanning in grayscale, the program
will select the optimal brightness value automatically.
The grayscale scanning mode retains more information about the letters in the scanned text to
achieve better OCR results when recognizing documents of medium to poor quality. You can also
correct some of the defects manually using the image editing tools available in the Image Editor.
For details, see "Image Preprocessing."
Color mode
If you do not need to preserve the original colors of a full–color document, you can process the
document in black–and–white mode. This will greatly reduce the size of the resulting FineReader
document and speed up the OCR process. However, processing low –contrast images in black and
white may result in poor OCR quality. We also do not recommend black and white processing for
photos, magazine pages, and texts in Chinese, Japanese, and Korean.
Note: You can also speed up recognition of color and black–and–white documents by selecting the
Fast reading option on the Read tab of the Options dialog box. For more about the recognition
modes, see OCR Options.
