1 results about "Low-intensity laser" patented technology

Method for manufacturing a valuable or secure product (100), comprising the steps: - Providing a core layer (102) of the value or security product (100), - Applying at least one laser-compatible foil layer (106) to the core layer (102) or to one or more polymer layers (104) applied to the core layer (102), - Incorporating person-specific and / or product-specific non-tactilely detectable information (108) into the laser-compatible foil layer (106) using a low-intensity laser beam, and - Forming person-specific and / or product-specific information in the form of at least one tactilely detectable Braille character (110) with a high-intensity laser beam which is higher than the low intensity, wherein a cover layer which is only partially opaque is applied to the laser-capable foil layer (106), and wherein the cover layer is opaque at least in one of the places where a blackening has been introduced into the underlying laser-capable foil layer (106) by the laser beam.
