The duplicate field checker must be enabled for every field in your label vision template that needs to be checked for duplication across any of your labels.

Follow these steps to ensure duplicates are checked accurately:

1. Enable the duplicate field checker feature for every field that must be unique.

2. Select a product reference. 

- A product reference could be your identity number, an internal part number, your customer’s part number etc.

- Whatever product reference is chosen, Perceptor will check for duplicates against that reference.

- Additional product references can be applied so for checking at multiple levels.

3. Save these settings to your label vision template.

With this feature enabled and a product reference applied for every field to be checked, Perceptor will be able to check for, identify and overstrike any duplicates.
