These are ways to increase processing speed in OmniPage Pro:
Increase Computing Power
This affects speed the most. A Pentium III computer is faster than a Pentium II, which is faster than a Pentium and so on. You should have a minimum of 16MB RAM, but as with most CPU-intensive programs, more memory improves processing speed in OmniPage Pro.
Select Faster Settings or Deselect Slower Settings
Choose Options All...
in the Tools menu and click the tab in the Options dialog box for the
settings you want to change:
Move the OCR Method slider to the Fastest end in the OCR tab. This will decrease processing time, but may cause text recognition to be less accurate.
Deselect Automatically correct page orientation in the Process tab. Make sure to select the proper Orientation option for your page in the Scanner tab.
Deselect Automatically straighten page image in the Process tab. Make sure to align your page with the proper edges of the scanner.
Deselect Look for tables when creating zones automatically in the Tables tab if your page does not contain tables.
Recognize Only the Text You Need
Draw zones around only the parts of a page you want to process. This saves OmniPage Pro the time of processing text you do not need.
You can also draw Ignore zones around areas of a page you do not want processed and have OmniPage Pro find zones and recognize text on the remainder of the document.
