Introduction
This is a brief guide on the text recognition feature in Adobe Acrobat1. OCR, which stands for Optical Character Recognition – is a process which adds an invisible text layer to scanned paper documents or screenshots to help make them text searchable. While OCR can be very helpful in terms of search, it is not perfect. The computer is interpreting pictures of letters and characters in documents and attempting to turn them into text. Sometimes, those translations are incorrect (Figures 1 and 2).
