Faced with increasingly diversified consumer needs, the food and beverage industries are developing new products almost on a daily basis, diversifying packaging materials and designs in the process.
Given such circumstances, manufacturers have been looking for a sensor capable of detecting colour marks printed on all sorts of materials to keep their plant running stably. Our new colour mark sensors E3S-DC photoelectric sensor and E3NX-CA fiber amplifier are ideally suited to these conditions because they incorporate our proprietary sensing technology and algorithm to detect subtle colour differences under various conditions. The sensors not only reliably detect colour marks on a variety of packaging materials including highly reflective materials, but also help optimize initially set parameters to adjust to changes in manufacturing lots thanks to our bank function.
We now offer three mark detection starter kits to get you up and running in no time. Scroll down the page for the kit's details. Variety in packaging increases the number of false detections Highly-reflective glossy packaging, such as aluminum vapor deposition material Low-reflection packaging, such as film with fine Colourful packaging with little difference in colour between the mark and background With designs becoming more colourful, there are times when there is little difference in colour between the colour mark and the design elements background.
There are cases when colours of packaging materials vary from lot to lot. In such a case, it can be difficult to determine the cause of the problem—resulting in time lost due to troubleshooting and a notable reduction in productivity.
Bank function Our sensors can store 8 or 9 different setups. This information can be managed in a database containing details of colour variations between different lots of packaging materials. The sensor can then be automatically adjusted to compensate for lot variations.
This eliminates the risk of detection errors and unnecessary plant shutdowns when changing lots.
