At first glance, diffraction black looks like it’s printed in paint, but tilt the Black Lidogram and look at the device at an acute angle to see the black change to a rich, pure color of red or green. This feature is also used as a distinctive feature of Black Lidogram when checking for authenticity.
As a result, we have created an optical diffraction device that has unique properties and is successfully used to protect brands, products and documents.
Black Lidogram devices combine extraordinary aesthetic and security features and are used in the design of tax stamps, ID documents, passports, and banknotes.
