Why does OCR not appear to work on parts of my document?

Answer:

Because OCR is a complex conversion that relies on consuming recognizable text, certain document characteristics may degrade the quality of optical character recognition output. For example, the following conditions may impair OCR quality:

• A dark colored background
• A source document with multiple languages
• A rotated source document
• Scanning under light conditions that are too bright or dark
• A network connection and an Adobe Document Cloud connection is required
