Continuous inkjet (CIJ) printers are commonly used to print dates and codes on frozen goods because of their versatility on the packaging line. However, the low temperatures typical of these processing facilities can lead to printing issues, making it critical to carefully select specialized inks and CIJ printers that can provide reliable performance and achieve high print quality and proper code adhesion throughout a product’s lifecycle.
Cold Temperatures: CIJ inks are engineered to perform well over a specific range of temperatures. Among the coldest common operating environments, the temperatures in frozen foods production environments are often below the typical temperature specifications of many inks. Only certain inks are specifically formulated to achieve the best adhesion, durability and printer performance in colder environments down to 0°C.
