Multiple Laser Image (MLI)/ Changeable Laser Image (CLI)

A Multiple Laser Image (MLI) is similar to a Changeable Laser Image (CLI). These are easy to verify visible authenticity features, whereby different images become visible (generally 2), such as, for example, a portrait, a logo, a symbol and a number, depending on the viewing angle.

MLI is used when the ridges are horizontal and CLI when the ridges are vertical.
