Adjusting Image Resolution
Image resolution shows the fineness of detail that can be distinguished in an image and is measured in dots per inch (dpi).
The best resolution for OCR is 300 dpi.
Important! ABBYY FineReader shows best OCR performance when vertical and horizontal resolutions are the same.
Very high resolution settings (greater than 600 dpi) slow down the OCR process without greatly enhancing quality. Resolution values
lower than 150 dpi adversely affect OCR quality.
You may need to adjust the resolution of your images if:
The resolution of your image is less than 200 dpi or greater than 600 dpi
Your image has non–standard resolution.
Faxes, for example, may have a resolution of 204 x 96 dpi.
To adjust the resolution:
1. Click the Scan button.
2. In the dialog box, specify the desired resolution.
Depending on which scanning interface is being used, either the ABBYY FineReader scanning dialog box or the scanner driver
dialog box will open.
3. Scan the document.
Tip: You can also adjust the resolution of your images in the Edit Image dialog box (Page>Edit Page Image…).
Scanning Facing Pages
When scanning facing pages of a book, both pages will appear as a single image. See sample image.
To improve OCR quality, split the facing pages into two separate images. In ABBYY FineReader, images of facing pages can be split
automatically or manually.
To split facing pages automatically:
1. Select Tools>Options… and click the 1. Scan/Open tab.
2. Under Image processing, select Split dual pages.
3. Scan the facing pages.
To split facing pages manually:
1. Open the Edit Image dialog box (Page>Edit Page Image…).
2. Use the options and buttons in the Split menu to split your image.
Straightening Text Lines
When scanning very thick books, the text close to the binding may be distorted. Similarly, when photographing text with a digital
camera, the text close to the margin may be distorted.
To remedy line distortions:
1. Select Page>Edit Page Image…
2. Click Deskew & Straighten and then click Straighten Text Lines.
