Videojet V474 and V519 thermochromic inks turn from black to blue after a retort process. Capable of penetrating waxy surface deposits, the inks produce legible codes with high optical character recognition read rates. Their MEK-free formula includes pentanone and ethanol for relatively fast dry times on a variety of food container substrates such as metal cans, plastic pouches, bowls and glass jars.
