To meet code requirements before, during, and after the retort process, Videojet releases ink innovations, V476 and V521, for use with its 1000 Line of continuous inkjet printers.
The V476 can be used 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 116-121°C.
This allows processors to determine whether or not a particular item has been properly exposed to the retort process.
“These new inks are an example of Videojet innovation in fluids for ink jet technology,” states Heidi Wright, business unit manager for supplies.
Methyl ethyl ketone (MEK) and methanol-free, the inks provide a clear color-change from dark red to light red and offer reduced bleeding of the code as compared to other thermochromic ink offerings.
Primary uses for V476 and V521 inks are for processed food containers such as metal cans, glass jars, flexible pouches, plastic bowls, and trays.
These inks may also be used in food or pharmaceutical applications where the goal is to reduce certain solvent plant emissions, including MEK.
