Markem-Imaje: Code verification system

Markem-Imaje offers the Detect-Plus code verification system on its SmartDate® thermal transfer overprinter coders that can prevent product recalls and scrap by verifying the presence, position, and quality of printed codes directly on film packaging. Unit can check and confirm code quality at a rate up to 350 packs/min at 300 dpi.


Unlike other systems which infer code information by checking the TTO ribbon, Detect-Plus assesses prints on each pack ensuring codes do not jeopardize compliance through their absence, or package appeal by misplacement. Ribbon check systems, by contrast, can tell you the code has been printed but not that it was at the wrong angle or missed the pack entirely.

Compact and adjustable, the print and detect system is designed to fit easily into the majority of medium to high-volume packaging lines. Its IP65 rating (standard on camera, optional on SmartDate coders) makes it ideal for the most challenging production environments.

Cost-efficient and designed to be ‘plug and play’, it does not require the purchase of any external hardware or software during installation. Once installed, the SmartDate user interface immediately interacts with the camera to check and confirm conformity of the code on the pack. In case of a fault, the user interface will automatically emit a warning for corrective action.

Engineered with flexibility in mind, the Detect-Plus system is compatible with all SmartDate X-Series ribbons. When used with ribbon saving modes, Detect-Plus users can thus also enjoy up to 20% in ribbon savings. While competing market options also offer ribbon saving options, this mode does not tend to work as well with ribbon check systems. During this mode, the code is somewhat faded on the ribbon, making it harder to detect the code’s existence at the ribbon level. Because Detect-Plus checks the product, not the ribbon, its code validation process is not compromised when the ribbon saving mode is activated.

The system is a kit that can be purchased new with, or retrofitted to, SmartDate X40 or SmartDate X60 coders. The verification system is now available throughout Europe, Canada, and the United States. It will be gradually rolled out to other parts of the world over the course of the year.
