Code detection system
Automatically checking for the presence of an ink jet-printed code on every product, the Videojet code detection system is used for flat packaging with a white or light marking window. Using presence/absence detection, the system verifies the amount of contrast in the marking area is sufficient and helps catch common printing issues such as missing, mispositioned and clipped codes. It allows setting a threshold for a code to be considered unacceptable, as well as a limit for the number of bad codes that can be detected before a fault is indicated. When the specified quantity of bad codes is detected, the system automatically sends an alert signal to eject product or stop the production line.
