What to do if you see a message prompting you to change the

resolution

Recognition quality depends on the resolution of the document image. Low image resolutions

(below 150 dpi) may have a negative impact on recognition quality, while images with excessively

high image resolutions (over 600 dpi) do not yield any significant i mprovements in recognition

quality and take a long time to process.

The message prompting you to change the image's resolution can appear if:

 The resolution of the image is less than 250 dpi or greater than 600 dpi.

 If the image has a non–standard resolution. For example, some faxes have a resolution of

204 by 96 dpi. For best recognition results, the vertical and horizontal resolutions of the

image must be the same.

Complete the following steps to change the resolution of an image:

1. Click the Scan button.

2. Select a different resolution in the scanning dialog box.

Note: We recommend using a resolution of 300dpi for documents that do not contain any

text smaller than 10 points. Use a resolution of 400вЂ“600 dpi for text that is 9 points or

smaller.

3. Scan the image.

Tip: You can also use the Image Editor to change an image's resolution. To open the Image Editor,

on the Page menu, click Edit Image…).

Scanning facing pages

When you scan facing pages of a book, both pages will appear on the same image.

To improve OCR quality, images with facing pages need to be split into two separate images. ABBYY

FineReader 12 features a special mode that automatically splits such images into separate pages

within the FineReader document.
