A common problem when scanning text from newspapers or magazines is that 'bleed' is picked up in the form of the scanner seeing the text on the obverse of the page being scanned. This can have the effect of reducing the effictiveness of your OCR software's capability.

You can improve the recognition of scanning articles on thinner material by placing a sheet of black paper or light card behind the page when scanning. (You may already note that some scanners have a black background to resolve this problem.)

This has proved to be a suitable solution for me when scanning from newsprint, magazine articles and reference books.
