CLP installs QuadTech Inspection System

The QuadTech Inspection System was chosen for its ability to inspect translucent and transparent flexible packaging materials, without the need for white ink, so simplifying production and enabling cost savings. Prior to this, CLP had been printing white to provide a target to help other inspection systems function on such substrates. However, as white ink wasn't requested by customers, it was a cost that CLP had to absorb. This not only included ink costs, but also extended to pre-press time, flexo plates and gravure cylinders too.

To eliminate the practice of printing white to facilitate inspection, the QuadTech Inspection System uses a combination of three LED lights, one of which is a reflected light illuminating the back of the web. The resulting image on the control screen can then be adjusted to show a black, white or gray background to create the necessary contrast to enable accurate fault detection and eliminate the additional ink.

Part of the Tadbik Group, CLP serves customers in the food, medical and healthcare markets. It is widely known as a producer of high-quality flexible packaging for brands, but also as a developer of innovative applications including retort laminates and pouches, taste-free water packaging and others.

Israel Moran, supply chain manager at CLP, said: ‘While quality control is a top priority for us, it was an expensive process to undertake on translucent and transparent substrates. So, when we decided to install a new W&H press, we took the opportunity to see if there was a solution on the market that could inspect without the need to print white for inspection.

‘Fortunately, following a visit to the QuadTech stand at drupa 2012, we quickly established that there was. This resulted in the installation of our QuadTech Inspection System.’

Caroline Zimmer, QuadTech regional sales leader, added: ‘We were very pleased to help solve this technical challenge for CLP. With brands demanding ever more exacting print quality standards, it is increasingly important for businesses such as CLP to find technologies to meet their needs, but also, do this while reducing overall costs and increasing profitability.’
