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 highten the contrast and brighten the document for better legibility.
For editing instructions see our online Help.
Also, make sure the scan is cropped so that all the text is completely horizontal. Crooked text is not recognized by the OCR engine.
(Applies to PDFpen Scan+ 1.5 and later in iOS 8 and later).
