■Advantages of Print Inspection
The print inspection offers fast evaluation through intelligent character library. The OCV/OCR camera system is fully format-free. The method used by scanware is feature-based. However, scanware does not use every single character read as a comparison, as this would either be at the expense of evaluation time or accuracy. Instead, SIGNUM Print calculates a virtual character from all characters read and recognised as correct, which represents the average of all variants read. Thus, only one comparison needs to be made for each character to inspect its correctness and readability.
