Readiris Pro is probably one of the most powerful OCR packages for PCs allowing you to turn documents into editable text in seconds.
In fact, Readiris Pro probably has more features than you'll ever need but the most important thing is that its very accurate. Readiris Pro also does an excellent job of preserving formatting.
The interface is slicker in this latest version with more helpful step-by-step scanning hints than before.
Readiris Pro is very accurate in faithfully recreating the original format of your documents and replaces columns of text, tables, and graphics in the output file.
There are also a decent choice of output formats and Readiris Pro makes it really easy to publish converted PDFs to the web thanks to a WYSIWYG web editor.
Readiris Pro isn't perfect though. While accuracy is well over 90%, the jury is out whether its more accurate than ABBYY FineReader. However, the accuracy of formatting is superb and probably the best you'll find on PC.
