OCR doesn't work very well in PDFpen Scan+, why?
Poor OCR results from poor scan quality. If your scan is dull and the text is blurry and hard to read, OCR will have trouble. Please use the edit screens of PDFpen Scan+ to lighten the contrast and brighten the document for better legibility.
Also, make sure the scan is cropped so that all the text is completely horizontal. Crooked text is not recognized by the OCR engine.
PDFpen Scan+ has been discontinued in September 2019.
