SECURITY THREAD WITH A MAGNETIC ELEMENT

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.

PRINTED TINY TEXT

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".
