Digital Ink Technologies has introduced an invisible, edible ink that can be used instead of stickers to authenticate fresh produce.
On hand to talk about the innovation at Auspack, Digital Ink Technologies managing director Michael Mahoney said the FDA-approved solvent-based ink, called Polytij, could be seen under ultraviolet light.
It gives producers, distributors and retailers a new way to tag individual products with pick or best-before dates, or as a way to differentiate premium produce from cheaper alternatives on the checkout.
"A visible version of the ink is also available instead of stickers for marking produce as, for example, organic," Mahoney said.
"This enables producers to print directly on produce lines and gives them a number of new capabilities."
