LOOK-numbering2_IMAGE_1COLSecurity from laser beams. With LOOK (Laser Originated Optical Key), banknote printing companies brings banknotes into the age of the laser. LOOK is a laser marking method that uses ultramodern laser technology to individually adapt established security features and thereby create new ones.
In this way, laser marking significantly expands the technical scope for banknote design. On the one hand, color-shifting effects can be integrated more easily, and even customized. On the other, see-through effects can be incorporated (or embedded) into existing features with greater ease. Finally, almost any design or position of banknote numbers is possible, and they can be printed on the front and back of the note in a single pass.
