specifications.
Inaccuracies in the OCR process can have many causes.
Analyze the types of paper, scanners, and resolution levels that
are used in the process to optimize the OCR results before
setting up the OCR processes.
The following are some tips for increasing OCR accuracy.
File-format issues: Color documents do not capture image
details accurately. When the process input is a color image,
lower-quality OCR documents result. Review any color
document requirements and consider using higher-resolution
scanning to increase accuracy.
Document-quality issues: Low-quality paper documents are
another major cause of lower OCR accuracy. Lower-quality
documents generally increase the error rate in the OCR
process. When working with such documents, consider the
following factors to increase the OCR accuracy:
• Try to obtain and use higher-quality paper documents.
• Consider using a scanner that has a different scanner-
bulb color, which might work better with the paper color of
the document.
• Test a higher-level scan resolution.
• Consider using the image process in advance of OCR to
clean up the image.
