Kodak introduces invisible security ink for its NEXPRESS digital presses

The Red Fluorescing Dry Ink operates in the fifth toner unit of the NEXPRESS and can be used to print static or variable content inline. The ink, which is clear but visible when viewed at an angle to the sheet, glows red when exposed to ultraviolet light. The applications that immediately come to mind are concert and other event tickets, airline and other travel tickets, Personal ID cards, VIP passes for events, VDP promotions (come on down to the Auto Kingdom and put your ticket under our special lamp to see if you're a winner...), Lottery and other games of chance, and more. 

The ink can print images, text or barcodes just like any of the other plates in the VDP stream, and will be available  in June of 2010.
