You’d never know there’s a code here… until you turn on the UV light
Here’s the thing about invisible anti-counterfeit solutions: they have to be truly invisible. This UV fluorescent red CIJ ink prints on black and white plastic caps with zero visibility under normal lighting. No smudges, no shadows, no hints. But for quality control or authenticity checks, a simple UV lamp reveals a bright red fluorescent code in seconds. Industries like cosmetics, personal care, beverages, and lubricants are using this for covert traceability and diversion control. Would this work for your product caps? Let us know in the comments.
