  • Patent number: 11651114
    Abstract: A method for designing a magnetic plate allowing magnetic particles contained in magnetic ink distributed at different densities includes estimating a distribution of the magnetic particles allowing the magnetic ink to be spread, estimating forms of magnetic field applying the magnetic force to the magnetic particles in order for the magnetic ink to be spread in a desired magnetic printing pattern within the printing layer, obtaining adjustment factors of the magnetic plate corresponding to the estimated forms of the magnetic field by using a model for which deep learning or machine learning has been performed using design conditions including at least one of an upper surface structure of the magnetic plate and a magnetization property of the magnetic plate and obtaining a parameter for the magnetic plate configured to form the magnetic printing pattern based on the obtained adjustment factors.
    Type: Grant

  • Patent number: 11348725
    Abstract: Disclosed are a stereoscopic magnetic print film formed using magnetic particles and a method of manufacturing the stereoscopic magnetic print film. The method includes preparing magnetic ink including magnetic particles, forming a printing layer on a base layer using the prepared magnetic ink, and forming a stereoscopic pattern by applying a magnetic field to the printing layer.

  • Patent number: 11331932
    Abstract: A magnetic domain drawing apparatus includes a magnetic plate moving module including a magnetic plate seating part configured to hold a magnetic plate seated thereon and a magnetic plate moving part configured to move the magnetic plate seating part, and at least one of magnetic domain deforming modules disposed to be spaced apart from the magnetic plate seating part at a predetermined distance and configured to deform a magnetic domain of the magnetic plate when the magnetic plate is seated on the magnetic plate seating part. The at least one of magnetic domain deforming modules is configured to deform the magnetic domain of the magnetic plate by applying at least one of heat, a magnetic field and an external force to the magnetic plate.
