Accuracy of image is affected when the brightness settings are too high or too low. According to this guide 50% brightness is ideal. OCR quality is affected by straightness of initial scan. When pages are skewed, recognition will not be accurate. When documents to be scanned are old or discolored, they may be scanned in RGB mode to ensure capture of all image data.

Points to consider about the Text

Texts which were published prior to 1850 may not be compatible with the OCR software. But, if the pages that are to be scanned are found in a different language, there are many OCR tools that allow the user to select the language of the document. OCR quality will be poor if the documents are with lower contrast. Printed pages give better OCR results when compared to typed scripts. OCR accuracy is also affected because of inconsistent use of font faces and sizes.

On completion of the original recognition process, the user must check and correct the text to ensure 100% accuracy. The system will never carry out this check. When there are large amounts of text and also when original text is of poor quality, the editing process may require more amount of time. Anyone can use the OCR software since it requires no special skills. One can use the OCR tool as a scanning software in case he/she wants to scan the original document.
