Fluorescing UV ink is only visible under UV lighting
Videojet has introduced new UV fluorescing ink for its 8610 Thermal Inkjet printer to print ‘invisible’ codes that can only be seen under black light to improve product traceability of high end cosmetics, pharmaceuticals and other consumer goods.
The American product identification firm’s new ink is colourless in normal light and fluoresces blue under a black light. With its MEK solvent base, the ink adheres to a variety of substrates including coated cartons or glossy labels, vial caps and closures, and dark substrates where a barcode is needed.
The ink is suitable for GS1-DataMatrix and other 2D codes, and is resistant to the autoclave process. It offers a 2-3 second dry time on non-porous materials such as ABS, HDPE, PET, PVC and nylon.
‘This ink was initially developed for the pharmaceutical market; however, it is also suited to a variety of other applications including retort processed food containers and cosmetic packaging,’ said Heidi Wright, business unit manager, TIJ & TTO, at Videojet.
