Setting Up the Read Text Identification Tool

Once the tool has been added, you will need to select the type of region and then configure it in the image:

Position the region over the text and make sure that the boundaries of the region cover the text (see the Selecting Text to Read topic for more information). To help speed up the performance of the tool, try and create smaller regions; the larger the region, the longer it will take the tool to perform its inspection.
Press the OK button to confirm the region (press the Cancel button to not add the tool to the job).
After the region has been accepted, you will need to define the Mode of operation (Read, Verify or Read and Verify) choose the type of Font (OCR-A Black on White, OCR-A White on Black, OCR-B Black on White, OCR-B White on Black, or Custom), and specify the number of characters in the Field String or Match String parameter in the Settings tab, depending on the Mode.
- If you selected Read as the Mode of operation, and an OCR-A or OCR-B as the Font type, specify the number of characters in the Field String parameter and press the Tune button to set the proper scale.
- If you selected Verify or Read and Verify as the Mode of operation, and an OCR-A or OCR-B as the Font type, enter the characters in the Match String parameter and press the Tune button to set the proper scale.
  Note: If you are using any of the OCR-A or OCR-B Fonts, the characters in the image must be between 15 and 60 pixels high. Press the Tune button to properly scale your characters. If your characters are smaller than 15 pixels or larger than 60 pixels, you will need to create a Custom Font.
- If you selected Custom for the Font type, first press the Train Font button and create a Font library. Once you have created your Font library, select your Mode of operation, and specify the number of characters in the Field String parameter for Read Mode, or enter the number of characters in the Match String parameter for Verify or Read and Verify Mode.
- You can use up to four custom fonts (for example, "Custom_1," "Custom_2," "Custom_3" and "Custom_4") within a single job, and a trained font can be shared between Read Text Identification Tools when more than one custom font is added to the job.
With the tool initially configured, load several images and adjust the tool's parameters, as needed, to compensate for your expected ranges of variations.
Finally, if desired, use the tool's Input/Output properties to share tool data between other tools and/or other external devices.
