Food manufacturers have utilized the retort or autoclave process for years, typically to help preserve vegetables, beans, fruit, soup, sauces, baby food, meat/fish, ready-to-eat meals and pet food. To meet code requirements before, during, and after the retort process, Videojet (videojet.co.uk) is pleased to announce its latest ink innovations, V476 and V521, for use with its 1000 Line of Continuous Inkjet (CIJ) printers. V476 is qualified for use in Videojet standard 1000 Line printers and V521 for use in its 1000 Line Ultra High Speed models.

Codes produced with these new inks are designed to provide a noticeable color change from dark red to light red when exposed to heat and moisture during the retort process. The color change occurs after the material has been retorted for several minutes at 240-250°F (116-121°C). This allows processors to determine whether or not a particular item has been properly exposed to the retort process.
