Videojet launches color-changing inks for retort applications

V476 is for the Videojet standard 1000 Line printers and V521 for the 1000 Line Ultra High Speed models.

Codes produced with the inks are designed to provide a color change from dark 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) allowing processors to determine whether an item has been properly exposed to the retort process.

Videojet claims they offer reduced bleeding of the code compared to thermochromic ink offerings.

Heidi Wright, business unit manager for supplies at Videojet, said it is continually looking for ways to deliver fluids formulations to meet customer needs.  

“These new inks are a result of our dedicated research and development initiatives. Working closely with our customers to determine their production needs, we collect application data that can be used in creating formulations for a specific set of production requirements.”​ 

Primary uses for V476 and V521 inks are processed food containers such as metal cans, glass jars, flexible pouches, plastic bowls, and trays.
