Poor–quality documents are best scanned in grayscale. When scanning in grayscale, the program
will select the optimal brightness value automatically.
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.
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 ABBYY
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.
To select a color mode:
• Use the Color mode drop–down list in the New Task window or
• Use the options under Color mode on the Document tab of the Options dialog box
(Tools>Options…) or
• Click
or in the Pages window.
Important! Once the document is converted to black–and–white, you will not be able to restore
the colors. To get a color document, open the file with color images or scan the paper document in
color mode.
Document Languages
ABBYY FineReader recognizes both mono– and multi–lingual (e.g. written in two languages)
documents. For multi–lingual documents, you must select several recognition languages.
To specify an OCR language for your document, either in the Document Languages drop–down list
on the main toolbar (or in the New Task window if you are using quick tasks), select one of the
following:
