Uses of black light for authentication and counterfeiting prevention, such as internal check codes.
For checking ink that cannot be easily seen! Illuminated and photographed with 'PW-UV343H-03L'.
Here are examples of the use of black lights in authentication and counterfeit prevention. Photographed by illuminating delivered mail with "PW-UV343H-03L." Ink barcodes that can be seen when exposed to ultraviolet light are printed. Since they cannot be seen under normal conditions, they can be printed in prominent positions. This technology is applied to sensing technologies that automatically recognize large quantities of products and packages. 【What is a Black Light】 - A general term for lights that emit wavelengths shorter than 400nm in the visible spectrum (ultraviolet light). - Fluorescent reactions that cannot be obtained with visible light, as well as various reactions depending on the subject, can be observed. - Used widely for purposes ranging from hobby applications like fluorescent verification and glow-in-the-dark lures to counterfeit detection of banknotes and industrial ultraviolet flaw detection lamps. *For more details, please refer to the related links or feel free to contact us.
