Latest Patents
One of Harms' latest patents is a security element with a diffraction structure that includes subareas representing recognizable information. This innovative security element is designed for documents of value and features an area with a diffraction structure that reconstructs a diffractive image under specific viewing conditions. The subareas do not participate in the image reconstruction but represent recognizable information that is primarily visible under the same conditions that reveal the diffractive image.
Another significant patent is for antifalsification paper, which incorporates an embedded safeguarding thread. This thread is designed to be freely accessible in certain areas and has a width greater than 2 mm. The antifalsification paper consists of at least two layers produced on separate paper machines. The first layer contains openings that allow partial access to the safeguarding thread, while the second layer is firmly connected to the first and contributes to the overall thickness of the paper. The use of wide safeguarding threads enhances the resistance to forgery, making this paper a valuable asset in security applications.
