Overview of Batch OCR

The Optical Character Recognition (OCR) module recognizes and translates printed alphanumeric characters on a scanned image document and image-only PDFs into characters in a text document. OnBase OCR supports 18 languages, making it an ideal solution for international companies or businesses with document sets in multiple languages.

The following output formats are available.
• ASCII Text (Standard)
• ASCII Text (Formatted)
• PDF (several varieties)
• Microsoft Word
• HTML 3.2
• HTML 4.0
• Rich Text Format
• Unicode Text (Standard)
• Unicode Text (Formatted)


OCR is performed after an image has been scanned, Document Import Processed, or swept into OnBase. OCR settings can be created and saved for multiple Document Types.

Batch OCR at Carleton

OCR processing at Carleton occurs on a virtual server that runs the OnBase "Thick" client as a Windows service. This server requires no interaction from users of OnBase, as it's merely a way for images to be processed to include a text rendition of the scanned image. The OnBase Batch OCR server runs with the following parameters:

Products Registered: Batch OCR, Production Document Imaging (Kofax or TWAIN), Workstation Client

Server hostname: onbaseocr.ads.carleton.edu

User Windows service runs as: ADS\onbase_ocr_svc

Command line switches: -ODBC="OnBase-production" -SCHED -SCANAUTOOCR -SCANAUTOQUEUE:0
