Resumen de: WO2023247969A2
A method of making a magnetic security feature, particularly a security thread with a magnetic element, which is harder to counterfeit and so more secure. A layer of ink 3 comprising a first set of particles and a second set of particles in suspension within the liquid ink is printed onto a substrate 2. The particles are magnetically anisotropic and acicular. Then, a permanent magnet 7 is moved along the printed ink layer, followed by an electromagnet 8 which is turned on and off selectively as it is moved along the printed ink layer 3. The electromagnet 8 has a magnetic field strength which is higher than the coercivity of the particles of the second set but lower than the particle of the first set. The resulting magnetic security feature 1 has a magnetic pattern across it, which has subtle differences between areas over which the electromagnet 8 was turned off versus those over which it was turned on. These subtle differences are harder for counterfeiters to notice and/or copy, resulting in a more secure document to which the magnetic security feature 1 is applied.

Resumen de: EP4545307A1
Methods and systems for defining characters, can involve selectively removing pixels from one or more characters and rendering a character with a user space equivalent to a device space. Multiple abutting non-line pixels can be removed among the pixels from the character(s). Furthermore, the character(s) including the multiple abutting non-line pixels as expected for the character(s) can be created prior to prior to selectively removing the pixels from the character(s). This approach can avoid partially marked pixels by setting user space equal to device space and then selectively removing pixels when printing microtext. Selective pixel removal allows for more white space and better recognition of characters such as, for example, "8" and "E".

A luminescent printing ink for security printing includes a fluorescent substance and a phosphorescent substance which each luminesce in the visible spectral range when excited with non-visible excitation light. The printing ink contains one or more capsule luminescent pigment varieties, each of which has a core, a shell encapsulating the core and a luminescent substance present in the core. The fluorescent substance and the phosphorescent substance are each present as a luminescent substance in the core of one or more of the capsule luminescent pigment varieties so that the capsule luminescent pigments form fluorescent capsule luminescent pigments and/or phosphorescent capsule luminescent pigments. The luminescences of the fluorescent and the phosphorescent capsule luminescence pigments have the same light-fastness and the same chemical stability, and their luminescences visually produce a substantially matching colour impression.
