This case study details the cable marking solution implemented by Cables RCT, a manufacturer of low-voltage flexible cables based in Zaragoza, Spain. The company produces a wide variety of cables and faces significant challenges in ensuring that each cable is marked correctly with essential information such as brand name, voltage, and compliance data. To address these challenges, Cables RCT utilizes a system of ten Markem-Imaje inkjet printers controlled by CoLOS® packaging intelligence software. This automated system allows operators to scan barcodes, ensuring accurate and efficient printing while minimizing the risk of coding errors. The case study outlines the specific requirements for cable marking, including the need for durability and readability under various conditions. It also highlights the flexibility of the printing system, which accommodates different cable types and colors, ultimately enhancing production efficiency and reliability. Cables RCT's long-term partnership with Markem-Imaje has proven beneficial in maintaining high-quality standards in their production processes.
