Coding & Marking process is not an easy operation. It is fairly common for plants to process their containers at high speed, which makes it difficult to mark a good marking.
This can lead to defected or lack of marking.
E2M COUTH® offers the VERIFITEXT which is an artificial vision inspector designed to inspect all kinds of marks, such as texts, dates, Datamatrix, EAN, etc.
When the defects are detected the product is removed from the line with a rejection system.
